Rare Vector-Vector B Decays:
a Laboratory for Strong and Weak Dynamics
Andrei Gritsan

Rare B meson decays are of interest because they provide an opportunity to
measure the weak-interaction parameters of the unitarity triangle and to
search for elementary particles and interactions beyond the Standard Model.
Understanding the origin of CP and Time symmetry violation in the weak
interactions and search for physics outside the Standard Model became the
focus of the modern high energy physics experiments such as BABAR. Rare
vector-vector B decays are of special interest because their angular
distributions reflect strong and weak interaction dynamics. Particular
vector-vector decays have special features. The `penguin' decays
B-> Φ K* and B-> ρ K* are good places to look for new physics
participating in the penguin loops. The B-> ρ ρ decays have
advantages over π π for measuring unitarity triangle angle α as a
consequence of smaller penguin contributions. We will present the first
experimental study of these on BABAR.
