Tritium beta-decay endpoint for a Tachyonic Neutrino that travels Faster than Light
Ngee-Pong Chang
In this paper, we study the tritium decay in the field theory of the superluminal (faster-than-light) neutrino. We show how the unstable transient modes with $\vec{q} \cdot \ve…

Chirality in the Early Universe
Ngee Pong Chang
The early big bang is an alphabet soup of quarks, W bosons, gluons, and other exotic particles and flavors. In the usual scenario, there is no place for the pion. It dissociates in…

Braaten-Pisarski Action, Disoriented Chiral Condensate, and Chiral Symmetry Non-Restoration
Ngee-Pong Chang
The QCD effective action at high T shows a manifest global chiral symmetry. And calculations show that the order parameter \psibarpsi vanishes above T_c. It has been popular to ref…
