Constrains on new Higgs scalars from LHC recent data

Click For Summary

Discussion Overview

The discussion centers on the constraints imposed by recent LHC data on the study of new Higgs scalars, particularly in relation to decay channels such as h -> WW and h -> ZZ. Participants explore how specific figures from research papers can inform model parameters in the context of heavier scalars.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant inquires about the implications of LHC data on their study of new Higgs scalars and how specific figures can inform model parameters.
  • Another participant mentions a recent CMS paper that excludes heavy Higgs bosons up to several hundred GeVs, noting that ATLAS exclusions are comparable but not identical.
  • A later contribution references additional CMS exclusions on neutral MSSM Higgs bosons, indicating that models with h or H at 125 GeV +/- require a tan beta of around 12 or less, while acknowledging that these exclusions are not model independent.

Areas of Agreement / Disagreement

Participants do not reach a consensus, as there are multiple competing views regarding the implications of the LHC data and the specific constraints on Higgs models.

Contextual Notes

The discussion highlights limitations related to model independence and the specific assumptions underlying the exclusions mentioned, which may affect the applicability of the results to different models.

Hi all,

I wonder if I study new Higgs scalars, How the data of the LHC for searching for heavier scalars
in h-> WW->lvlv and h -> ZZ-> 4 l channels like in [arXiv:1304.0213] can make constrain on my
study for the new Higgs?

How a figure like figure 2 can give me data for my model free parameters ..

Bests,
S.S.

CMS recently pre-published a paper excluding heavy Higgs bosons up to the high hundreds of GeVs http://arxiv.org/abs/1405.4158; the exclusions from ATLAS aren't quite the same but are comparable.

Hi guys,

Thanks, I got it.
 
More CMS exclusions on neutral MSSM Higgs bosons (h, H and A) are found at http://arxiv.org/pdf/1408.3316.pdf

The main takeaway is that any MSSM with h or H at 125 GeV +/- needs to have tan beta of around 12 or less. Obviously, these exclusions are not model independent, but they do provide another perspective on the issue of extra Higgs boson exclusions.
