Implications on the Heavy CP-even Higgs Boson from Current Higgs Data

High Energy Physics - Phenomenology 2013-03-27 v2 High Energy Physics - Experiment

Abstract

The current Large Hadron Collider data indicates that the newly observed resonance has the WW and ZZ modes consistent with the standard model Higgs boson, while the \gamma\gamma mode is about 1.2 - 2 times that of the standard model prediction and the tau-pair mode is suppressed. If this pattern persists in the upcoming data, it would be a sign for physics beyond the standard model. In the type II two-Higgs-doublet model, it is the region where \sin\alpha \approx 0 and a moderately large \tan\beta = 10 - 20 that the lighter CP-even Higgs boson can accommodate the current data. We note that in this region the heavier CP-even Higgs boson must have a large decay branching ratio into tau pairs. We find that this heavier Higgs boson can be observable in the associated production with a b\bar b pair and through the decay into a tau pair.
