It is shown that the proton "spin crisis'' or "spin puzzle" can be understood by the relativistic effect of quark transversal motions due to the Melosh-Wigner rotation. The quark helicity $\Delta q$Expand
Lorentz violation from cosmological objects with very high energy photon emissions
Abstract Lorentz violation (LV) is predicted by some quantum gravity theories, where photon dispersion relation is modified, and the speed of light becomes energy-dependent. Consequently, it resultsExpand
Light speed variation from gamma-ray bursts
Abstract The effect of quantum gravity can bring a tiny light speed variation which is detectable through energetic photons propagating from gamma ray bursts (GRBs) to an observer such as the spaceExpand
Lorentz violation from gamma-ray bursts
The constancy of light speed is a basic assumption in Einstein’s special relativity, and consequently the Lorentz invariance is a fundamental symmetry of space–time in modern physics. However, it isExpand
Empirical mantissa distributions of pulsars
Abstract The occurrence of digits one through nine as the leftmost nonzero digit of numbers from real world sources is often not uniformly distributed, but instead, is distributed according to aExpand
Quark Wigner distributions in a light-cone spectator model
We investigate the quark Wigner distributions in a light-cone spectator model. The Wigner distribution, as a quasi-distribution function, provides the most general one-parton information in a hadron.Expand
Light flavor asymmetry of nucleon sea
The light flavor antiquark distributions of the nucleon sea are calculated in the effective chiral quark model and compared with experimental results. The contributions of the flavor-symmetricExpand
Reduced-order surrogate models for scalar-tensor gravity in the strong field regime and applications to binary pulsars and GW170817
We investigate the scalar-tensor gravity of Damour and Esposito-Far\`ese (DEF), which predicts nontrivial phenomena in the nonperturbative strong-field regime for neutron stars (NSs). Instead ofExpand
Quantization of Black Holes
We show that black holes can be quantized in an intuitive and elegant way with results in agreement with conventional knowledge of black holes by using Bohr's idea of quantizing the motion of anExpand
A prediction of neutrino mixing matrix with CP violating phase
Abstract The latest experimental progress has established three kinds of neutrino oscillations with three mixing angles measured to rather high precision. There is still one parameter, i.e., the CPExpand
