Abstract

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 p(T)(mu) > 1.5 GeV and pseudorapidities - 1.6 < eta(mu) < 2.3, as a function of p(T)(mu), eta(mu), Q(2) and Bjorken x. The charm and beauty contributions to the proton structure function F(2) were also extracted. The results agree with previous measurements based on independent techniques and are well described by QCD predictions.

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) &gt; 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 p(T)(mu) &gt; 1.5 GeV and pseudorapidities - 1.6 &lt; eta(mu) &lt; 2.3, as a function of p(T)(mu), eta(mu), Q(2) and Bjorken x. The charm and beauty contributions to the proton structure function F(2) were also extracted.
