Production of Z boson pairs via gluon fusion in the minimal supersymmetricmodel - art. no. 075004

We present the full one-loop calculation for gg-->ZZ in the minimal supersy mmetric standard model (MSSM) including nonresonant contributions from the squark loop diagrams and provide analytical expressions for the helicity am plitudes. The one-loop process gg-->ZZ via quark loops has been calculated in the standard model. In supersymmetric models, additional contributions a rise from squark loops. In some regions of the MSSM parameter space, the to p and bottom squark loops can make important contributions to the diagrams involving Higgs bosons. The heavy Higgs scalar (H) might be detected at the CERN Large Hadron Collider via gg-->H-->ZZ for tan beta less than or equal to 5. [S0556-2821(99)00707-9].
