چکیده
Triple product correlations (TPC’s) involving strange quark spin are elucidated in b → uūs process within the standard model. They arise when light quark masses are nonzero. As the momenta and spins of constituent quarks are related to that of the parent hadron, the quark masses are, however small, important and relevant in TPC studies. At this level the TPC’s of interest are of the form ~ss · (~ pu × ~pū) and ~ss · (~ ps × ~ pu). As an application, we look at T -violating effects in B0 → Λ̄pπ through the TPC ~sΛ̄ · (~ pΛ̄ × ~pp) for which triple product asymmetry is found to be 2–3% in the vanshing limit of strong phase.
