Measurement of Open Charm and Double Open Charm Production Cross Sections and Ratios in pp Collisions at √s = 2.76 TeV with the LHCb Experiment

Enzio Crivelli

In proton-proton collisions, mechanisms other than gluon-gluon fusion can contribute to double charm production. One possible additional source is double parton scattering (DPS). The theory of Quantum Chromodynamics can not precisely predict DPS production cross sections, since simplifications have to be used. Double open charm production cross sections in proton-proton collisions at LHCb have been measured so far at a centre of mass energy of √s = 7 TeV. These provide valuable input for the theoretical understanding of DPS. In this work such double open charm production cross sections are measured at LHCb at √s = 2.76 TeV using D⁰ and D⁺ mesons in the final state.
