Pseudoscalar Higgs Production in Association with Stop and Sbottom Pairs at the211 LHC in the MSSM

摘要

The authors study the processes within the theoretical framework of the211u001eSupergravity (SUGRA) inspired Mininal Supersymmetric Standard Model (MSSM) at the 211u001eleading order (LO) in perturbative Quantum Chromo-Dynamics (QCD). Other than 211u001econsituting a novel production mechanism of the neutral, CP-odd Higgs particle, 211u001ethey also allow one to relate the size of the corresponding production rates to 211u001ethe ratio of the vacuum expectation values of the two Higgs fields tan beta, to 211u001ethe trilinear couplings A(sub O) and to the sign if the Higgsino mass term sign 211u001e(micro). This interplay is made easier by the absence of any mixing of the 211u001evertices, contrary to the case of all other Higgs bosons of the theory.
