Origin of fermion generations from extended noncommutative geometry
Hefu Yu, Bo-Qiang Ma
We propose a way to understand the 3 fermion generations by the algebraic structures of noncommutative geometry, which is a promising framework to unify the standard model and gene…
Light speed variation from gamma ray bursts: criteria for low energy photons
Yue Liu, Bo-Qiang Ma
We examine a method to detect the light speed variation from gamma ray burst data observed by the Fermi Gamma-ray Space Telescope (FGST). We suggest new criteria to determine the c…
Lorentz violation from gamma-ray burst neutrinos
Yanqi Huang, Bo-Qiang Ma
The Lorentz violation~(LV) effect of ultra-relativistic particles can be tested by gamma-ray burst~(GRB) neutrinos and photons. The IceCube Collaboration has observed plenty of ult…
Testing Lorentz invariance and CPT symmetry using gamma-ray burst neutrinos
Xinyi Zhang, Bo-Qiang Ma
A recent work [Y. Huang and B.-Q. Ma, Commun. Phys. {\bf 1}, 62 (2018)] associated all four PeV neutrinos observed by IceCube to gamma-ray bursts (GRBs), and revealed a regularity…
Nonperturbative strange-quark sea from lattice QCD, light-front holography, and meson-baryon fluctuation models
Raza Sabbir Sufian, Tianbo Liu, Guy F. de Téramond +5
We demonstrate that a nonzero strangeness contribution to the spacelike electromagnetic form factor of the nucleon is evidence for a strange-antistrange asymmetry in the nucleon's…
Quark-antiquark asymmetry of helicity distributions in the nucleon sea
Mengyun Liu, Bo-Qiang Ma
We study the helicity distributions of light flavor quark-antiquark () pairs in the nucleon sea. The valence quarks are handled by adopting the light-cone SU(6) quark-sp…
