Contribution

It provides a detailed calculation of $t\bar{t}h(H)$ production cross sections and decay distributions within the MSSM framework using optimized parameters.

Findings

Calculated cross sections at 13 and 14 TeV energies.

Identified optimal MSSM parameters consistent with ATLAS data.

Analyzed decay channels and kinematic distributions of Higgs bosons.

Abstract

We studied the properties of the MSSM Higgs bosons, h and H through the decay into b-quarks in associated production with a top-quark pair. There was used the tree-level Higgs sector described by two parameters M$_A$ and tan$\beta$ and found their optimal values according to experimental data of ATLAS detector. Using the restricted parameter space we calculated cross sections of associated $t\bar{t}h(H)$ production at 13 and 14 TeV, the corresponding kinematical cuts, mass distributions and Branching Ratios of h and H decays into $b\bar{b}$ quark pair.
