This paper is concerned with the physics of meson decays to J/psi and phi.These decays have been observed at the Tevatron [7] and, in particular, should be copiously observed at the LHCb detector. This paper gives a concise presentation of…

Within the standard model (SM), the time dependent CP asymmetries in B -> psi K_S, B -> eta' K_S and B -> phi K_S are expected to give the same result i.e. sin (2 beta). However recent measurements of the mixing induced CP asymmetries in B…

I present some of the most recent BaBar measurements for rare B decays. These include rate asymmetries in the B decays to K(*) l+ l- and K+ pi- and branching fractions in the B decays to l+ nu_l, K_1(1270)+ pi- and K_1(1400)+ pi-. I also…
