Two knees and the Evasion of Greisen-Zatsepin-Kuz'min Cutoff in Cosmic Ray Spectrum -- Are Neutrinos the Tachyons?
Guang-Jiong Ni, Zhi-Qiang Shi
The whole spectrum of high-energy cosmic ray (HECR) is, very likely, influenced by tachyonic neutrinos. Especially, the appearance of two knees can be fitted by the tachyon mass $m…
The Lifetime Asymmetry of Polarized Muons in Flight
Zhi-Qiang Shi, Guang-Jiong Ni
Based on the parity violation in Standard Model, we study the dependence of the lifetime on the polarization of an initial-state fermion in weak interactions. The fermion lifetime…
Calculation on the Lifetime of Polarized Muons in Flight
Zhi-Qiang Shi, Ni Guang-Jiong
The fermion lifetime was usually calculated in terms of spin states. However, after comparing spin states with helicity states and chirality states, it is pointed out that a spin s…
Studies on the Weak Charges of Particles
Zhi-qiang Shi
In order to include massive neutrino theoretically, a new concept of the weak charges of the particles, fundamental fermions, intermediate bosons and hadrons, is introduced. A new…
