Soft Hadronic Interactions
Quantum Chromodynamics is the generally accepted field theoretical prescription of strong interactions and is successfully applied to processes where a hard scale is present, given by either a highly virtual particle, a large transverse momentum or a large mass of the exchanged particles. In such processes the strong coupling constant is small enough to allow for perturbative calculations and Q...
متن کاملALPGEN, a generator for hard multiparton processes in hadronic collisions
This paper presents a new event generator, ALPGEN, dedicated to the study of multiparton hard processes in hadronic collisions. The code performs, at the leading order in QCD and EW interactions, the calculation of the exact matrix elements for a large set of parton-level processes of interest in the study of the Tevatron and LHC data. The current version of the code describes the following fin...
متن کاملConsistency of data on soft photon production in hadronic interactions.
The glob model of Lichard and Van Hove and the modified soft annihilation model (MSAM) of Lichard and Thompson are used as a phenomenological tool for relating results from various experiments on soft photon production in high energy collisions. The total phenomenological expectation is composed of contributions from classical bremsstrahlung, the soft annihilation model and the glob model. The ...
متن کاملPhoton Pair Production With Soft Gluon Resummation In Hadronic Interactions
The production rate and kinematic distributions of isolated photon pairs produced in hadron interactions are studied. The effects of the initial–state multiple soft–gluon emission to the scattering subprocesses qq̄, qg, and gg → γγX are resummed with the Collins–Soper–Sterman soft gluon resummation formalism. The effects of fragmentation photons from qg → γq, followed by q → γX, are also studied...
