T-Violation in B Decays
(Alakabha Datta, David London)

We study T-violation in B decays to two vector mesons, B-> VV.If CPT is 
conserved then violation of T implies the violation of CP and vice versa.  
However, T- violation is proportional to the cosine of the strong phase while 
direct CP violation is proportional to the sine of the strong phase.  Hence 
T-violation and CP- violation are complementary to each other and the 
simultaneous measurement of both asymmetries is very useful to test the 
standard model or to look for new physics.  We find several B->VV decays 
which have no T-violation in the standard model.  Hence a measurement of 
non-zero T-violation in these decays would be a clear signal of new physics.  
We discuss models of new physics that can lead to large T-violation in these 
modes.
