Authors:J. H. Field First page: 103001 Abstract: The indirect estimation of the Higgs Boson mass from electroweak radiative corrections within the
Standard Model is compared with the directly measured value obtained by the ATLAS and CMS
Collaborations at the CERN LHC collider. Treating the direct measurement of m H as input, the
Standard Model indirect estimation of the top-quark mass is also obtained and compared with its
directly measured value. A model-independent analysis finds an indirect value of m H of ≃70 GeV,
below the directly measured value of 125.7±0.4 GeV and an indirect value: m t =177.3±1.0 GeV, above
the directly measured value: 173.21±0.87 GeV. A goodness-of-fit test to the Standard Model using all
Z-pole observables and m W has a χ 2 probability of ≃2%. The reason why probability values about a
factor of ten larger than this, and indirect estimates of m H about 30 GeV higher, have been
obtained in recent... Citation: Chinese Physics C PubDate: 2017-09-27T23:00:00Z DOI: 10.1088/1674-1137/41/10/103001 Issue No:Vol. 41, No. 10 (2017)

Authors:A-Meng Zhao; Yuan-Mei Shi, Jian-Feng Li Hong-Shi Zong First page: 103101 Abstract: In this work, we calculate the equation of state (EoS) of quark gluon-plasma (QGP) using the
Cornwall-Jackiw-Tomboulis (CJT) effective action. We get the quark propagator by using the rank-1
separable model within the framework of the Dyson-Schwinger equations (DSEs). The results from CJT
effective action are compared with lattice QCD data. We find that, when μ is small, our results
generally fit the lattice QCD data when T> T c , but show deviations at and below T c . It can be
concluded that the EoS of CJT is reliable when T> T c . Then, by adopting the hydrodynamic code
UVH2+1, we compare the CJT results of the multiplicity and elliptic flow ν 2 with the PHENIX data
and the results from the original EoS in UVH2+1. While the CJT results of multiplicities generally
match the original UVH2+1 results and fit the experimental data, the CJT results of ν 2 are

Authors:Chong-Xing Yue; Lu Ma, Yu-Chen Guo Ya-Bing Zuo First page: 103102 Abstract: The Elementary Goldstone Higgs (EGH) model is a perturbative extension of the standard model (SM),
which identifies the EGH boson as the observed Higgs boson. In this paper, we study pair production
of the EGH boson via gluon fusion at the LHC and find that the resonant contribution of the heavy
scalar is very small and the SM-like triangle diagram contribution is strongly suppressed. The total
production cross section mainly comes from the box diagram contribution and its value can be
significantly enhanced with respect to the SM prediction. Citation: Chinese Physics C PubDate: 2017-09-28T23:00:00Z DOI: 10.1088/1674-1137/41/10/103102 Issue No:Vol. 41, No. 10 (2017)

approximation using overlap fermions in quenched SU (3) gauge theory. Then we investigate the
topological structure of the quenched QCD vacuum, and compare it with results from the all-scale
topological density. The results are consistent. Random permuted topological charge density is used
to check whether these structures represent underlying ordered properties. The pseudoscalar glueball
mass is extracted from the two-point correlation function of the topological charge density. We
study 3 ensembles of different lattice spacing a with the same lattice volume 16 3 ×32. The results
are compatible with the results of all-scale topological charge density, and the topological
structures revealed by multi-probing are much closer to all-scale topological charge density than
those from eigenmode expansion. Citation: Chinese Physics C PubDate: 2017-09-28T23:00:00Z DOI: 10.1088/1674-1137/41/10/103104 Issue No:Vol. 41, No. 10 (2017)

Authors:Yue-Liang Wu First page: 103106 Abstract: The relativistic Dirac equation in four-dimensional spacetime reveals a coherent relation between
the dimensions of spacetime and the degrees of freedom of fermionic spinors. A massless Dirac
fermion generates new symmetries corresponding to chirality spin and charge spin as well as
conformal scaling transformations. With the introduction of intrinsic W-parity, a massless Dirac
fermion can be treated as a Majorana-type or Weyl-type spinor in a six-dimensional spacetime that
reflects the intrinsic quantum numbers of chirality spin. A generalized Dirac equation is obtained
in the six-dimensional spacetime with a maximal symmetry. Based on the framework of gravitational
quantum field theory proposed in Ref. [1] with the postulate of gauge invariance and coordinate
independence, we arrive at a maximally symmetric gravitational gauge field theory for the massless
Dirac fermion in six-dimensional spacetime. Such a theory is governed by the local spin gauge
symmetry SP (1,5) and ... Citation: Chinese Physics C PubDate: 2017-09-28T23:00:00Z DOI: 10.1088/1674-1137/41/10/103106 Issue No:Vol. 41, No. 10 (2017)

have been investigated at energies below and near the Coulomb barrier. The angular distributions of
α-particle production differential cross sections have been obtained at several projectile energies

scattering angular distributions have been compared with the predictions of continuum-discretized
coupled channels (CDCC) calculations. The influence of breakup coupling has also been investigated
by extracting dynamic polarization potentials (DPP) from the CDCC calculations. From the predictions
of CDCC calculations the relative importance of the nuclear, Coulomb, and total breakup
contributions have also been investigated. The nuclear breakup couplings are observed to play an

Authors:B. S. Hu; Q. Wu F. R. Xu First page: 104101 Abstract: In many-body perturbation theory (MBPT) we always introduce a parameter N shell to measure the
maximal allowed major harmonic-oscillator (HO) shells for the single-particle basis, while the
no-core shell model (NCSM) uses N max ℏ Ω HO excitation truncation above the lowest HO configuration
for the many-body basis. It is worth comparing the two different methods. Starting from “bare” and
Okubo-Lee-Suzuki renormalized modern nucleon-nucleon interactions, NNLO opt and JISP16, we show that
MBPT within Hartree-Fock bases is in reasonable agreement with NCSM within harmonic oscillator bases
for 4 He and 16 O in “close” model space. In addition, we compare the results using “bare” force
with the Okubo-Lee-Suzuki renormalized force. Citation: Chinese Physics C PubDate: 2017-09-27T23:00:00Z DOI: 10.1088/1674-1137/41/10/104101 Issue No:Vol. 41, No. 10 (2017)

Authors:Cen-Xi Yuan First page: 104102 Abstract: A shell-model investigation is performed to show the impact on the structure of 14 C from the
off-diagonal cross-shell interaction, 〈 pp V sdsd 〉, which represents the mixing between the 0
and 2 ħω configurations in the psd model space. The observed levels of the positive states in 14 C
can be nicely described in 0–4 ħω or a larger model space through the well defined Hamiltonians,
YSOX and WBP, with a reduction of the strength of the 〈 pp V sdsd 〉 interaction in the latter.
The observed B (GT) values for 14 C can be generally described by YSOX, while WBP and their
modifications of the 〈 pp V sdsd 〉 interaction fail for some values. Further investigation shows
the effect of such interactions on the configuration mixing and occupancy. The present work shows
examples of how the off-diagonal cross-shell interaction strongly drives the nuclear structure. Citation: Chinese Physics C PubDate: 2017-09-27T23:00:00Z DOI: 10.1088/1674-1137/41/10/104102 Issue No:Vol. 41, No. 10 (2017)

Authors:Chen Li-Zhu; Zhao Ye-Yin, Pan Xue, Li Zhi-Ming Wu Yuan-Fang First page: 104103 Abstract: We study the influence of measured high cumulants of conserved charges on their associated
statistical uncertainties in relativistic heavy-ion collisions. With a given number of events, the
measured cumulants randomly fluctuate with an approximately normal distribution, while the estimated
statistical uncertainties are found to be correlated with corresponding values of the obtained
cumulants. Generally, with a given number of events, the larger the cumulants we measure, the larger
the statistical uncertainties that are estimated. The error-weighted averaged cumulants are
dependent on statistics. Despite this effect, however, it is found that the three sigma rule of
thumb is still applicable when the statistics are above one million. Citation: Chinese Physics C PubDate: 2017-09-27T23:00:00Z DOI: 10.1088/1674-1137/41/10/104103 Issue No:Vol. 41, No. 10 (2017)

by the ARGO-YBJ experiments. In this paper, we demonstrate that the observed H + He spectrum can be
reproduced well with a model of cosmic rays escaping from the supernova remnants (SNRs) in our
Galaxy. In this model, particles are accelerated in a SNR through a non-linear diffusive shock
acceleration mechanism. Three components of high energy light nuclei escaped from the SNR are
considered. It should be noted that the proton spectrum observed by KASCADE can be also explained by
this model given a higher acceleration efficiency. Citation: Chinese Physics C PubDate: 2017-09-27T23:00:00Z DOI: 10.1088/1674-1137/41/10/105101 Issue No:Vol. 41, No. 10 (2017)

to −1.60%/°C statistically for each detector element. During 2016, DAMPE’s temperature changed by
∼8°C due to solar elevation angle, and the corresponding energy scale bias is about 9%. By frequent

accelerators, and needs to be carefully investigated. The core problem in the analysis is to obtain
the time evolution of effective cavity voltage under transient beam loading. To simplify the
problem, the second order ordinary differential equation describing the behavior of the effective
cavity voltage is intuitively simplified to a first order one, with the aid of two critical
approximations which lack proof of their validity. In this paper, the validity is examined
mathematically in some specific cases, resulting in a criterion for the simplification. It is
popular to solve the approximate equation for the effective cavity voltage numerically, while this
paper shows that it can also be solved analytically under the step function approximation for the
driven term. With the analytical solution to the effective cavity voltage, the transient reflected

consists of two oscillators generating middle-infrared and far-infrared laser covering the spectral
range of 2.5–200 μm. In this paper, we numerically study the output characteristics of the
middle-infrared oscillator with accurate cavity length detuning. Emphasis is put on the temporal
structure of the micropulse and the corresponding spectral bandwidth. Taking the radiation
wavelengths of 50 μm and 5 μm as examples, we show that the output pulse duration can be tuned in
the range of 1–6 ps with corresponding bandwidth of 13%–0.2% by adjusting the cavity length
detuning. In addition, a special discussion on the comb structure is presented, and it is indicated
that the comb structure may arise in the output optical pulse when the normalized slippage length is
much smaller than unity. This work has reference value for the operation of FELiChEM and other FEL
oscillators. Citation: Chinese Physics C PubDate: 2017-09-27T23:00:00Z DOI: 10.1088/1674-1137/41/10/108101 Issue No:Vol. 41, No. 10 (2017)
