Adiabatic Gravitational Perturbation During Reheating
W. B. Lin, X. H. Meng, X. M. Zhang
We study the possibilities of parametric amplification of the gravitational perturbation during reheating in single-field inflation models. Our result shows that there is no additi…
Mass formulas and thermodynamic treatment in the mass-density-dependent model of strange quark matter
G. X. Peng, H. C. Chiang, J. J. Yang +2
The previous treatments for strange quark matter in the quark mass-density-dependent model have unreasonable vacuum limits. We provide a method to obtain the quark mass parametriza…
Spectra of Baryons Containing Two Heavy Quarks in Potential Model
Sheng-Ping Tong, Yi-Bing Ding, Xin-Heng Guo +4
In this work, we employ the effective vertices for interaction between diquarks (scalar or axial-vector) and gluon where the form factors are derived in terms of the B-S equation,…
CP violation in neutrino mixing matrix and leptogenesis
Yong Liu, Utpal Sarkar
The CP violation required in leptogenesis may have different origin, but in an effective theory they all are related to the rephasing invariant CP violating measure in the mixing m…
Further Study On U(1) Gauge Invariance Restoration
Chao-Hsi Chang, Yi-Bing Ding, Xue-Qian Li +4
To further investigate the applicability of the projection scheme for eliminating the unphysical divergence due to U(1) gauge invariance violation, we study the process $…
Charge and critical density of strange quark matter
G. X. Peng, H. C. Chiang, P. Z. Ning +1
The electric charge of strange quark matter is of vital importance to experiments. A recent investigation shows that strangelets are most likely highly negatively charged, rather t…
