Precision measurements with jets and particles at HERA
arXiv:1009.0989 · doi:10.1016/j.nuclphysbps.2010.10.004
Abstract
Inclusive jet and multijet cross sections measured in ep collisions in different kinematic regions by the H1 and ZEUS experiments are shown. The measurements are used to extract the strong coupling alpha_s as a function of the scale and at the mass of the Z-boson. Results from prompt photon production in comparison with pQCD calculations are shown in photoproduction and deep-inelastic scattering. Other topics address scaled momentum distributions of charged particles, a measurement of the transverse momenta of charged particles and the first measurement of the charge asymmetry at HERA.
