Test of T violation in neutral B decays

Abstract

T violation should be tested independently of CP violation. Besides K system, B meson decays provide another good place to study T violation. In the Standard Model, T violation in $B^0\rightleftharpoons \overline{B^0}$ oscillation is expected to be small. The angular distribution of $B\to VV$ decay permits one to extract the T-odd correlation. In the absence of final state interaction, T violation in $B\to J/\psi (l^{+}{l}^{-})K^{\ast }(K_S{\pi }^0)$ decay can reach $4-7$ via $B^0-\overline{B^0}$ mixing.
