Exploring CPT violation in $B\to J/\psi K$ decays using kaon regeneration

Abstract

We present an analysis of CPT violation in $B\to J/\psi K$ decays. A method of kaon regeneration is proposed to increase the $K_{S(L)}$ interference effects. With the time evolution of both neutral B and K mesons, we show that it is possible to determine the CPT violating parameter in $B^0-\overline{B^0}$ mixing or constrain it.
