P and CP violation in B Decays

While the Kobayashi--Maskawa model of CP violation passed its first crucial precision test in $B\to J/\psi K_S$, other CP asymmetries in $B$ and $B_s$ decays will have to be measured in order to critically test and overconstrain the model in an unambiguous way. On another front, the chirality of weak $b$-quark couplings has not yet been carefully tested. We discuss recent proposals for studying both the chiral and CP-violating phase structures of these couplings in $B\to D^*\rho$ and $B\to D^*a_1$.
