Updated calculations of the reach of Fermilab Tevatron upgrades for Higgs Bosons in the MSSM, mSUGRA, and mGMSB models

One of the crucial predictions of supersymmetric models that reduce to the Minimal Supersymmetric Standard Model (MSSM) at the weak scale is that the lightest Higgs scalar should have mass mh approxlt 125-130 GeV[1]. Recent results on the reach of Fermilab Tevatron upgrades for Standard Model (SM) Higgs bosons show that masses of order 120-180 GeV may be probed [2, 3, 4, 5], depending on integrated luminosity, detector performance and signal and background modeling. Thus, the discovery of a Higgs boson (or a new limit of around 120-130 GeV on its mass) will severely constrain supersymmetric models as well. In this report, we update previous calculations made by our group [6] pertaining to the reach of Fermilab Tevatron upgrades for Higgs bosons in supersymmetric models. We present reach results for SUSY Higgs bosons within the MSSM, the minimal Supergravity model (mSUGRA) and in the minimal Gauge Mediated SUSY Breaking model (mGMSB). In this update, 95% CL exclusion contours and 5σ discovery contours are presented for integrated luminosity values of 2, 5 and 20 fb-1
