Query: Clean Signals of CP-violating and CP-conserving New Physics in B->P V
  gamma Decays at B Factories and Hadron Colliders   In radiative B decays to final states containing one spin zero meson, one
spin one meson and a photon, the photon polarization can be measured from the
angular distribution of the final state. The P-odd, C-even components of this
distribution lead to triple correlation asymmetries that are very sensitive to
new physics as they are likely to receive only tiny contributions from the
Standard Model. There are also (CP-conserving) forward-backward asymmetries to
which there may be SM contributions of a few percent; nevertheless there is a
data driven means to overcome the SM ``pollution''. These latter observables
can be used to search for a class of New Physics which does not necessarily
possess a new CP-odd phase, and wherein the current structure is different from
the left-handed electroweak theory of the Standard Model. The mode $B^\pm \to
K^\pm \phi \gamma$ is particularly useful due to the relatively large branching
ratio and its distinctive final state but there are dozens of such final states
in the decays of $B_u$, $B_d$ and $B_s$ mesons where the analysis is
applicable. In many cases, after the decay of the spin one resonance, several
of these channels lead to only charged mesons and a photon in the final state,
so they may well be accessible in a hadronic environment in addition, of
course, to $e^+ e^-$ (Super) $B$ Factories. In passing we also briefly explain
why the CP-conserving forward-backward asymmetries in $B \to P V \gamma$ decays
is a more reliable signal of new physics compared to the (CP-conserving)
transverse polarization in $B \to V_1 V_2$ modes even though, of course, the
latter may be somewhat more abundant.
