Abstract

Abstract: The production of beauty and charm quarks in ep interactions has been studied with the ZEUS detector at HERA for exchanged four-momentum squared 5 < Q²< 1000 GeV²using an integrated luminosity of 354 pb⁻¹. The beauty and charm content in events with at least one jet have been extracted using the invariant mass of charged tracks associated with secondary vertices and the decay-length significance of these vertices. Differential cross sections as a function of Q², Bjorken x, jet trans- verse energy and pseudorapidity were measured and compared with next-to-leading-order QCD calculations. The beauty and charm contributions to the proton structure functions were extracted from the double-differential cross section as a function of x and Q². The running beauty-quark mass, m_bat the scale m_b, was determined from a QCD fit at next-to-leading order to HERA data for the first time and found to be m_b(m_b) = 4.07 ± 0.14 (fit)_{− 0.07} ^{+ 0.01}(mod.)_{− 0.00} ^{+ 0.05}(param.)_{− 0.05} ^{+ 0.08}(theo.)

The beauty and charm content in events with at least one jet have been extracted using the invariant mass of charged tracks associated with secondary vertices and the decay-length significance of these vertices. Differential cross sections as a function of Q2, Bjorken x, jet trans- verse energy and pseudorapidity were measured and compared with next-to-leading-order QCD calculations.
