Spectroscopy for the Bound States of a Top Squark (t) and a Heavy Quark

  • Based on the possibility that the life time of the lightest top squark 1(1) may be long enough and it may form a bound state with another quark before its decay has not been ruled out yet, we focus on the bound states of the lightest top squark 1(1) and a heavy quark Q(), and establish the Bethe Salpeter equation for the binding systems (c1) and (b1) (or their antiparticles) etc with QCD inspired kernel. We then investigate these systems and give their spectroscopy by means of instantaneous approximation.

Abstract: Based on the possibility that the life time of the lightest top squark 1(1) may be long enough and it may form a bound state with another quark before its decay has not been ruled out yet, we focus on the bound states of the lightest top squark 1(1) and a heavy quark Q(), and establish the Bethe Salpeter equation for the binding systems (c1) and (b1) (or their antiparticles) etc with QCD inspired kernel. We then investigate these systems and give their spectroscopy by means of instantaneous approximation.
