Left-Right Asymmetry of Weak Interaction Mass of Polarized Fermions in Flight

TL;DR

This paper investigates the polarization-dependent asymmetry in weak interaction mass of fermions, revealing that left-handed polarized fermions have greater weak interaction mass than right-handed ones, which impacts neutrino mass studies and parity violation understanding.

Contribution

It provides a theoretical calculation within the Standard Model showing polarization-dependent mass asymmetry in fermions in flight.

Findings

Left-handed fermions have greater weak interaction mass than right-handed ones.

The mass asymmetry is invariant across inertial frames.

Implications for neutrino mass and parity nonconservation are discussed.

Abstract

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 left-handed polarized fermions is always greater than that of right-handed polarized fermions in flight with the same velocity in any inertial frame. The asymmetry of the weak interaction mass might be very important to the investigation of neutrino mass and would have an important significance for understanding the parity nonconservation in weak interactions.
