Measurement of charm and beauty production in deep inelastic ep scattering from decays into muons at HERA

The production of charm and beauty quarks in ep interactions has been measured with the ZEUS detector at HERA for squared four-momentum exchange Q 2 >20 GeV 2 , using an integrated luminosity of 126 pb −1 . Charm and beauty quarks were identified through their decays into muons. Differential cros...

Description
Summary:The production of charm and beauty quarks in ep interactions has been measured with the ZEUS detector at HERA for squared four-momentum exchange Q 2 >20 GeV 2 , using an integrated luminosity of 126 pb −1 . Charm and beauty quarks were identified through their decays into muons. Differential cross sections were measured for muon transverse momenta and pseudorapidities −1.6< η μ
