Meson B fragmentation function with consideration of mass corrections
Study of B meson (meson with the bottom quark flavor) in Large Hadron Collider (LHC) is of special importance so that the detector LHCb is devoted to investigate these types of mesons. For this reason, in this paper we will study the production process of this meson in a phenomenological approach using the experimental data from electron-positron annihilation. In this regards, we shall calculat...
متن کاملLepton Pair Production at the LHC and the Gluon Density in the Proton
The production of lepton pairs in hadron collisions h1h2 → γX ; γ → ll̄ proceeds through an intermediate virtual photon via qq̄ → γ, and the subsequent leptonic decay of the virtual photon. Interest in this Drell-Yan process is usually focussed on lepton pairs with large mass Q which justifies the application of perturbative QCD and allows for the extraction of the antiquark density in hadrons [ ...
متن کاملHiggs production in hadron collisions: soft and virtual QCD corrections at NNLO
We consider QCD corrections to Higgs boson production through gluon–gluon fusion in hadron collisions. Using the recently evaluated [14]two-loop amplitude for this process and the corresponding factorization formulae [15, 16, 17, 18] describing soft-gluon bremsstrahlung at O(α2 S), we compute the soft and virtual contributions to the next-to-next-to-leading order cross section. We also discuss ...
متن کاملNLO QCD corrections to ZZ+jet production at hadron colliders
A fully differential calculation of the next-to-leading order QCD corrections to the production of Z-boson pairs in association with a hard jet at the Tevatron and LHC is presented. This process is an important background for Higgs particle and new physics searches at hadron colliders. We find sizable corrections for cross sections and differential distributions, particularly at the LHC. Residu...
متن کاملNNLO QCD corrections to the Higgs-strahlung processes at hadron colliders
We implement, at next-to-next-to-leading order, the QCD corrections to Standard Model Higgs boson production in association with vector bosons at hadron colliders, qq̄ → HV with V = W,Z. They consist of the two–loop corrections to the Drell–Yan process for the production of off-shell vector bosons, qq̄ → V , and in the case of Z final states, of the additional contribution from heavy-quark loop m...
