Measurement of cross section for beauty and charm events with dijets and a muon in the photoproduction regime at HERA are presented. The data were collected with the H1 detector and correspond to an integrated luminosity of 179 pb-1. The fractions of beauty and charm events are determined using the impact parameters of the muon tracks and their transverse momentum. The measurements are in agreement with QCD predictions at leading and next-to-leading order.
