HiggsBounds and HiggsSignals

HiggsBounds (12-12-2014 NEW VERSION!)

(P. Bechtle, O. Brein, S. Heinemeyer, O. Stål, T. Stefaniak, G. Weiglein and K. Williams)

HiggsBounds takes a selection of Higgs sector predictions for any particular model as input and then uses the experimental topological cross section limits from Higgs searches at LEP, the Tevatron and the LHC to determine if this parameter point has been excluded at 95% C.L..

Further information can be found in the following references:

In particular, consult the latest version of the HiggsBounds 4.x.x manual.

The HiggsBounds source files can be obtained from our download page.

You can also quickly run HiggsBounds via our online version (see below).

If you have any questions or comments, contact Tim or Oscar.


HiggsSignals (12-12-2014 NEW VERSION!)

(P. Bechtle, S. Heinemeyer, O. Stål, T. Stefaniak and G. Weiglein)

HiggsSignals performs a statistical test of the Higgs sector predictions of arbitrary models (using the HiggsBounds input routines) with the measurements of Higgs boson signal rates and masses from the Tevatron and the LHC.

The program is documented in:

The latest version of the user manual can be found here: HiggsSignals 1.x.x manual. Further information on the program and related issues can be found in

The HiggsSignals source files can be obtained from our download page.

If you have any questions or comments, contact Tim or Oscar.

Start with Step 1 if you'd like to test a general model or skip most of the steps by using one of the examples below.

Step 1 of 4: Give some information about the particle content of your model.

How many neutral Higgs bosons?

How many singly, positively charged Higgs bosons?



Examples

Standard Model Higgs with mass GeV.

Simple approximation to 4th Generation Model with Higgs mass GeV. (effective gluon-gluon-Higgs coupling is multiplied by 3 (good for MH much less than 2MT), photon-photon-Higgs coupling is not relevent).

Fermiophobic Higgs with mass 80 GeV. (effective Z-photon-Higgs coupling is not relevent).

CP violating MSSM example (CPX-like) at relatively small Mh1(TB=8, charged Higgs mass 125 GeV, other parameters as arXiv:1103.1335 p.5)

Mhmax values with MUE= 200 GeV, MA0= 200 GeV, TB= 20, MT= 173.1 GeV


Alternatively, enter all text from FeynHiggs Results webpage, generated using the FeynHiggs User Control Center (example). Assumes that any Higgs coupling or Higgs branching ratio which is not given explicitly is zero (you can edit this on the next page if you wish). (DOES NOT WORK AT THE MOMENT!)



You can also access HiggsBounds results for mSUGRA and MSSM-7+ scenarios (and many supersymmetric dark matter calculations) via DarkSUSY online.


Internally, HiggsBounds uses some SM results (see table 12 for references).
To access some of these quantities directly, enter a Higgs mass:
