Heavy-Flavor Production At Accelerators, Nikolaos Kidonakis
Heavy-Flavor Production At Accelerators, Nikolaos Kidonakis
Faculty and Research Publications
I discuss heavy flavor production at hadronic facilities. I present total cross sections and differential distributions for top quark, bottom quark, and charm quark production at the rrevatron and LHC colliders, and at fixed-target experiments such as HERA-B. The calculations include complete next-to-leading order corrections as well as higher-order soft-gluon corrections which are important near kinematical threshold.

We report measurements of the beam spin asymmetry in deeply virtual Compton scattering (DVCS) at an electron beam energy of 4.8 GeV using the CLAS detector at the Thomas Jefferson National Accelerator Facility. The DVCS beam spin asymmetry has been measured in a wide range of kinematics, 1.02<2.8 (GeV/c)2, 0.12<xB<0.48, and 0.1<−t<0.8 (GeV/c)2, using the reaction →ep→e′pX. The number of H(e,e′γp) and H(e,e′π0p) events are separated in each (Q2,xB,t) bin by a fit to the line shape of the H(e,e′p)X M2x distribution. The validity of the method was studied in detail …
