Mass Reconstruction

The problems of the Standard Model, as well as questions related to Higgs boson properties led to the need to model the ttH associated production and the Higgs boson decay to a top quark pair within the MSSM model. With the help of computer programs MadGraph, Pythia, and Delphes and using the latest kinematic cuts taken from experimental data obtained at the LHC, we have predicted the masses of MSSM Higgs bosons, A and H.

We use the kT–factorization approach to calculate total and differential cross sections of associated production of prompt photons and hadronic jets at the LHC energies. Our consideration relies on the pegasus Monte-Carlo generator with implemented ℴ(αα2s) off-shell gluon–gluon fusion subprocess g*g* → γqq− and several subleading quark-initiated contributions from ℴ(ααs) and ℴ(αα2s) subprocesses, taken into account in the collinear limit. Using Monte-Carlo generators CASCADE and PYTHIA, we investigate parton showering effects and compare our predictions with the data, taken by CMS and ATLAS collaborations at the LHC. We demostrate reasonabledescription of the data and the importance of parton shower effects in the kT–factorization.

Associated Production

We study the detection of the Higgs bosons predicted in the minimal SUSY standard model (h0, H0, A0 and H±). We find that after radiative corrections are considered, there is a region of parameter space where h0 will be out of the LEP reach. Some portion of this region can be covered at hadron colliders using the mechanism of associated production [Formula: see text], with h0→γγ. Other decays that may help to detect the neutral Higgses (produced either inclusively or in association with [Formula: see text]) are H→ZZ*, W+W−/ZZ, A0→Z+H0. We find that H± may be detected also through the decays H±→W±h0 and the associated production of H± with [Formula: see text].
