Determining β at the NLC with SUSY Higgs Bosons
Abstract
We examine the prospects for determining β from heavy Higgs scalar production in the minimal supersymmetric standard model at a future e+e- collider. Our analysis is independent of assumptions of parameter unification, and we consider general radiative corrections in the Higgs sector. Bounds are presented for s = 500 GeV and 1 TeV, several Higgs masses, and a variety of integrated luminosities. For all cases considered, it is possible to distinguish low, moderate, and high β. In addition, we find stringent constraints for 3β 10, and, for some scenarios, also interesting bounds on high β through tbH production. Such measurements may provide strong tests of the Yukawa unifications in grand unified theories and make possible highly precise determinations of soft SUSY breaking mass parameters.
