Pair Production of Neutral Higgs Particles in Gluon – Gluon Collisions
Pair production processes of neutral Higgs particles will allow us to study the trilinear Higgs couplings at future high–energy colliders. Several mechanisms give rise to multi–Higgs final states in hadron interactions. In the present paper we investigate Higgs pair production in gluon–gluon collisions. After recapitulating pair production in the Standard Model, the analysis of the cross sectio...
متن کاملSoft-gluon resummation for heavy quark production in hadronic collisions
We discuss the heavy quark production cross section near partonic threshold in hadronic collisions, including the resummation of leading and next-to-leading logarithms arising from soft gluon emission. We show how to handle the complications due to the non-universal nonleading logarithms. We give analytical results for the qq̄ partonic subprocess and numerical results in the DIS scheme for top q...
متن کاملGluon and charm distributions in the photon.
We study systematically the sensitivity of the photon structure function data on the gluon contents of the photon, by using the leading order Altarelli–Parisi (AP) equations. Charm quark contribution is studied in the quark parton model and by using the massive quark AP equations of Glück, Hoffmann and Reya. The present photon structure function data are found to allow wide range of gluon distr...
متن کاملFrom Unintegrated Gluon Distributions to Particle Production in Hadronic Collisions at High Energies
The inclusive distributions of gluons and pions for high-energy NN collisions are calculated. The results for several unintegrated gluon distributions (UGD’s) from the literature are compared. We find huge differences in both rapidity and pt of gluons and π’s in NN collisions for different models of UGD’s. The Karzeev-Levin UGD gives good description of momentum distribution of charged hadrons ...
متن کاملProduction of η′ from Thermal Gluon Fusion
We study the production of η′ from hadronizing thermal gluons using recently proposed η′ − g − g effective vertex. The η′ yield is found to be sensitive to the initial condition. At RHIC and LHC, the enhancement is large enough to be easily detected.
