Two-Higgs models for large $\tan \beta$ and heavy second Higgs. Journal of High Energy Physics 2008(2): 84. en_US dc.identifier.issn 1029-8479 en_US dc.identifier.uri http://nrs.harvard.edu/urn-3:HUL.InstRepos:8052099 dc.description.abstract We study two-Higgs models for large $\tan \beta$ and relatively large second Higgs mass. In this limit the second heavy Higgs should have small vev and therefore couples only weakly to two gauge bosons. Furthermore, the couplings to down-type quarks can be significantly modified (so long as the second Higgs is not overly heavy). Both these facts have significant implications for search strategies at the LHC and ILC. We show how an effective theory and explicit fundamental two-Higgs model approach are related and consider the additional constraints in the presence of supersymmetry or $Z_2$ flavor symmetries. We argue that the best tests of the two-Higgs doublet potential are likely to be measurements of the light Higgs branching fractions. We show how higher dimension operators that have recently been suggested to raise the light Higgs mass are probably best measured and distinguished in this way. en_US dc.description.sponsorship Physics en_US dc.language.iso en_US en_US dc.publisher Institute of Physics en_US dc.relation.isversionof doi:10.1088/1126-6708/2008/02/084 en_US dc.relation.hasversion http://arxiv.org/abs/0711.4360 en_US dash.license LAA dc.subject particle physics and field theory en_US dc.subject Higgs physics en_US dc.subject beyond standard model en_US dc.subject supersymmetry phenomenology en_US dc.subject phenomenology of high energy physics en_US dc.title Two-Higgs Models for Large $\tan \beta$ and Heavy Second Higgs en_US dc.type Journal Article en_US dc.description.version Author's Original en_US dc.relation.journal Journal of High Energy Physics en_US dash.depositing.author Randall, Lisa dc.date.available 2012-01-25T21:00:58Z dc.identifier.doi 10.1088/1126-6708/2008/02/084 * dash.contributor.affiliated Randall, Lisa
