Phenomena beyond the standard model (SM) can manifest themself indirectly, by affecting the production and decay of SM particles. The decay B0->K* mu mu is a flavor-changing neutral current (FCNC) process particularly sensitive, since it is heavily suppressed in the SM. Recent results from LHCb collaboration show a tension with respect SM prediction of more than 3 sigmas. We will present results of an angular analysis done by the CMS experiment at the LHC, using p-p data collected at sqrt(s)=8 TeV, corresponding to an integrated luminosity of L=20 fb^-1. The analysis is focused to measure the angular parameter P5', as well as P1, as a function of the di-muons invariant mass.
