Isolated Photons at Hadron Colliders at O ( αα 2 s ) ( II ) : Spin Dependent Case
نویسنده
چکیده
The cross section for inclusive prompt photon production with polarized hadron beams is calculated at order αα 2 s using the phase space slicing or analytic/Monte Carlo method. Isolation cuts are placed on the photon and the results are compared to a previous fully analytic calculation. Numerical results for the isolated cross section are presented for for p p → γ + X at RHIC center-of-mass energies with plausible isolation parameters using the most modern polarized parton densities evolved in next-to-leading order QCD. The perturbative stability of the asymmetries and scale dependence of the results are briefly discussed.

We discuss the spin properties of top quark pairs produced at hadron colliders at next-to-leading order in the coupling constant αs of the strong interaction. Specifically we present, for some decay channels, results for differential angular distributions that are sensitive to tt̄ spin correlations. PACS number(s): 12.38.Bx, 13.88.+e, 14.65.Ha
متن کاملOrigin of the k T smearing in direct photon production
We show that the Sudakov factor from the resummation of double logarithms ln(s/k T ) contained in the distribution functions is responsible for the kT smearing mechanism employed in the next-to-leading-order QCD (αα 2 s) calculations of direct photon production. s is the center-of-mass energy, and kT the transverse momentum carried by a parton in a colliding hadron. This factor exhibits the app...
