Exclusive Radiative B Meson Decays

We have investigated exclusive, radiative B meson decays to charmless mesons (ρ, ω, φ, K(892), K 2 (1430)) in 9.7× 106 BB̄ decays accumulated with the CLEO detector. The B → K(892)γ branching fractions are determined to be B(B0 → K∗0(892)γ) = (4.55 +0.72 −0.68 ± 0.34)×10−5 and B(B+ → K∗+(892)γ) = (3.76 +0.89 −0.83 ± 0.28)×10−5. We have searched for CP asymmetry in B → K(892)γ decays and measure ...

Exclusive Semileptonic Decays of Heavy Mesons

Exclusive semileptonic decays of heavy mesons provide interesting information on systems consisting of quarks of unequal mass. We express the formfactors of the hadronic current in terms of relativistic bound state wave functions for which we take the solutions of a relativistic harmonic oscillator potential. The wave function overlap is determined by the quark mass dependent longitudinal momen...

Scalar Mesons from Heavy Flavor Decays

In the past few years the B-factories became unexpected players in the scalar mesons business: in order to access the CP violation effects, it is necessary to handle the dynamics of the strong interaction between the final state hadrons. A number of large statistics studies heavy flavor decays involving a scalar component have been performed recently by Belle and BaBar, who have joined CLEOc, B...
