Study of Decays in PQCD Approach
Zhi-Tian Zou, Ying Li, Xin Liu
Within the framework of perturbative QCD approach based on factorization, we studied 40 decay modes in the leading order and leading power, where "S" stands for…
Numerical approximations of the Cahn-Hilliard and Allen-Cahn Equations with general nonlinear potential using the Invariant Energy Quadratization approach
Xiaofeng Yang, Guodong Zhang
In this paper, we carry out stability and error analyses for two first-order, semi-discrete time stepping schemes, which are based on the newly developed Invariant Energy Quadratiz…
Confronting the DAMPE Excess with the Scotogenic Type-II Seesaw Model
Ran Ding, Zhi-Long Han, Lei Feng +1
The DArk Matter Particle Explorer (DAMPE) has observed a tentative peak at $E\sim1.4~\TeV$ in the cosmic-ray electron spectrum. In this paper, we interpret this excess in the scoto…
Bayesian analysis of the break in DAMPE lepton spectra
Jia-Shu Niu, Tianjun Li, Ran Ding +3
Recently, DAMPE has released its first results on the high-energy cosmic-ray electrons and positrons (CREs) from about GeV to TeV, which directly detect a break at $\sim…
Stability and convergence analysis of A linear, fully decoupled and unconditionally energy stable scheme for magneto-hydrodynamic equations
Guodong Zhang, Xiaoming He, Xiaofeng Yang
In this paper, we consider numerical approximations for solving the nonlinear magneto-hydrodynamical system, that couples the Navier-Stokes equations and Maxwell equations together…
Global Analysis of Charmless Decays into Two Vector Mesons in Soft-Collinear Effective Theory
Chao Wang, Si-Hong Zhou, Ying Li +1
Under the framework of soft-collinear effective theory, we analyze the charmless decays in a global way at leading power in and leading order in with de…
