| Popis: | We use a sample of 384 million BBbar decays collected with the Babar detector at the PEP-II asymmetric e+e- storage ring to study the flavor-changing neutral current decays B->K(*)l+l-, where l+l- is either e+e- or mu+mu-. We present measurements in two dilepton mass bins, one below the J/psi resonance and the other above, of the lepton forward-backward asymmetry AFB and the longitudinal K* polarization FL in B->K*l+l-, along with isospin rate asymmetries in B->K*l+l- and B->Kl+l- final states. Comment: 6 pages, 3 eps figures, Parallel talk at ICHEP08, Philadelphia, USA, July 2008; revised fig 1(a), added fig 2, updated citations |
