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 $\alpha_s$ 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 $\alpha_s$ corrections and all-order resummation of large logarithmical corrections.
