Higgs boson production at the LHC in the framework of Regge limit of quantum chromodynamics

Abstract

In the framework of the L. N. Lipatov Reggeized Partons Theory we consider production of scalar Higgs boson H of the Standard Model and pseudoscalar Higgs boson A of the Minimal Supersymmetric Standard Model in the Reggeized gluon fusion at the energy range of the Large Hadron Collider. Working in the leading order approximation in the strong coupling constant αs we take into account contributions from t- and b-quark in the loop integrals. We have calculated transverse momentum boson spectra and total cross sections as a function of boson mass. The obtained results agree with predictions which have been obtained earlier in the collinear Parton Model with the next to leading order in αs corrections and all-order resummation of large logarithmical corrections.
