Angular analyses of b -> sll transitions at CMS

The flavour changing neutral current decays are interesting probes for searching for new physics. Angular distributions of b -> sl(+)l(-) transition processes of both B -> K*0 mu/+.0 and B+ -> K+mu(+)/mu/(-) are studied using a sample of proton-proton collisions at root 7s = 8 TeV collected with the CMS detector at the LHC, corresponding to an integrated luminosity of 20.5 fb-1. Angular analyses are performed to determine P1 and P5 angular parameters for B -> K* /mu(+)mu(-) and AFB and FH parameters for B+ -> K+mu(+)mu(-), all as functions of the dimuon invariant mass squared. All of the measurements are consistent with the standard model predictions.
