Complete description of polarization effects in emission of a photon by an electron in the field of a strong laser wave

We consider emission of a photon by an electron in the field of a strong laser wave. Polarization effects in this process are important for a number of physical problems. A probability of this process for circularly or linearly polarized laser photons and for arbitrary polarization of all other particles is calculated. We obtain the complete set of functions which describe such a probability in a compact invariant form. Besides, we discuss in some detail the polarization effects in the kinematics relevant to the problem of electron to photon conversion at photon-photon and photon-electron colliders.Comment: 18 pages, minor changes, published versio

Electroweak corrections to W\gamma and Z\gamma production at the LHC

We have calculated the electroweak O(\alpha) corrections to the processes p p -> Z \gamma + X -> \nu_l \bar{\nu}_l \gamma + X, p p -> Z \gamma + X -> l \bar{l} \gamma + X, and p p -> W \gamma + X -> \nu_l \bar{l} \gamma + X at the LHC, with l=e,\mu and \nu_l=\nu_e,\nu_\mu,\nu_\tau. The virtual corrections are evaluated in leading-pole approximation, whereas the real corrections are taken into account exactly. These corrections are implemented into a Monte Carlo generator which includes both phase-space slicing and subtraction to deal with soft and collinear singularities. We present numerical results for total cross sections as well as for experimentally interesting distributions. Applying typical LHC cuts, the electroweak corrections are of the order of -5% for the total cross sections and exceed -20% for observables dominated by high centre-of-mass energies of the partonic processes.Comment: 39 pages, LaTeX, 7 eps figure
