The analysis is based on data collected with the CMS detector at the LHC, corresponding to an integrated luminosity of 20.5 fb(-1). The forward-backward asymmetry A(FB) of the dimuon system and the contribution F-H from the pseudoscalar, scalar, and tensor amplitudes to the decay width are measured as a function of the dimuon mass squared. The measurements are consistent with the standard model expectations.eninfo:eu-repo/semantics/openAccessPARTICLEB-0Article2-s2.0-8505947718310.1103/PhysRevD.98.112011Q1WOS:000454168500003
