Splitting Functions
We extract the small x asymptotic behaviour of the Altarelli-Parisi splitting functions from their expansion in leading logarithms of 1/x. We show in particular that the nominally next-to-leading correction extracted from the Fadin-Lipatov kernel is enhanced asymptotically by an extra ln 1 x over the leading order. We discuss the origin of this problem, its dependence on the choice of factoriza...
متن کاملResummed heavy quark production cross sections to next-to-leading logarithm
We study how next-to-leading logarithms modify predictions from leading logarithmic soft-gluon resummation in the heavy quark production cross section near threshold. Numerical results are presented for top quark production at the Fermilab Tevatron and bottom quark production at fixed-target energies.
متن کاملPolarized Antenna Splitting Functions
We consider parton showers based on radiation from QCD dipoles or ‘antennae’. These showers are built from 2→ 3 parton splitting processes. The question then arises of what functions replace the Altarelli-Parisi splitting functions in this approach. We give a detailed answer to this question, applicable to antenna showers in which partons carry definite helicity, and to both initialand final-st...
متن کاملTimelike duality.
Several stationary solutions of the low energy string equations are dualized with respect to their timelike symmetry. Many of the duals have simple physical interpretations. Those of the nonextremal three dimensional black hole and black string are negative mass black strings. The extremal cases of these, and extremal higher dimensional black strings also, give negative energy plane fronted wav...
متن کاملAnomalous Dimensions and Splitting Functions
I explicitly calculate the anomalous dimensions and splitting functions governing the Q evolution of the parton densities and structure functions which result from the running coupling BFKL equation at LO, i.e. I perform a resummation in powers of ln(1/x) and in powers of β0 simultaneously. This is extended as far as possible to NLO. These are expressed in an exact, perturbatively calculable an...
