Please give a brief summary of your poster
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.
