Contribution

It presents new analytic results for Higgs-Z production in MSSM, incorporating both quark-antiquark and gluon-gluon fusion mechanisms with quantitative LHC predictions.

Findings

Cross sections computed for various MSSM scenarios.

Gluon fusion contributions are significant.

Provides compact analytic formulas for production processes.

Abstract

We study the hadroproduction of a CP-even or CP-odd neutral Higgs boson in association with a Z boson in the minimal supersymmetric extension of the standard model (MSSM) We include the contributions from quark-antiquark annihilation at the tree level and those from gluon-gluon fusion, which proceeds via quark and squark loops, and list compact analytic results. We quantitatively analyze the hadronic cross sections at the CERN Large Hadron Collider assuming a favorable supergravity-inspired MSSM scenario.
