Analytical Study of the Spin Projection Operator
Zhi-Qiang Shi
We present an analytical study of the spin projection operator of the spin state and the helicity state. It is pointed out emphatically that the former is Lorentz covariant, while…
Left-Right Asymmetry of Weak Interaction Mass of Polarized Fermions in Flight
Zhi-Qiang Shi
The left-right polarization-dependent asymmetry of the weak interaction mass is investigated. Based on the Standard Model, the calculation shows that the weak interaction mass of l…
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…
Experimental tests on the lifetime Asymmetry
Zhi-Qiang Shi, Guang-Jiong Ni
The experimental test problem of the left-right polarization-dependent lifetime asymmetry is discussed. It shows that the existing experiments cannot demonstrate the lifetime asymm…
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…
