Version 1.7.0 (28.03.2019) is available here: Download
After providing the corresponding links in the Makefile, we recommend for
fans of the MSSM:
to link SusHi to FeynHiggs (FH) by "./configure; make predef=FH"!
to link SusHi to FeynHiggs (FH) including the calculation of interference factors by "./configure; make predef=FHINT"!
to link SusHi to HiggsBounds/HiggsSignals+FH by "./configure; make predef=HB" or "HS"!
fans of the 2HDM:
to link SusHi to 2HDMC by "./configure; make predef=2HDMC"!


Newest features:
  • SusHi 1.7.0 can be called online,
    for now without linking an external code and for a limited set of PDF sets!
  • Version 1.7.0 introduces a command line option for the call of external codes without a direct link.
    The information is transfered through SLHA files. This option was developed by Lars-Thorben Moos.
  • The extension SusHiMi, described in 1611.09308,
    calculates gluon fusion and bottom-quark annihilation cross sections in the MSSM with
    complex parameters. It is now part of SusHi 1.7.0.
  • Version 1.6.0, published as SusHi Bento in 1605.03190,
    allows to calculate the gluon fusion cross section up to N3LO accuracy.
    For this purpose SusHi includes a soft expansion around the threshold of Higgs production.
    At lower orders 1/mtn terms can be added to the result in the heavy top-limit
    and a matching to the high-energy limit can be performed.
    The renormalization scale dependence can be obtained in a single run.
    The effect of Dimension-5 operators can be studied for all Higgs bosons.
    Moreover cross sections from the annihilation of two quarks can
    be calculated, see 1512.04901 for details.

Details

SusHi (Supersymmetric Higgs) is a Fortran code, which calculates Higgs cross sections
in gluon fusion and bottom-quark annihilation at hadron colliders in the SM,
the 2HDM, the MSSM and the NMSSM. Apart from inclusive cross sections up to
N3LO QCD, differential cross sections with respect to the Higgs' transverse
momentum and (pseudo)rapidity can be calculated. In case of gluon fusion,
SusHi contains NLO QCD contributions from the third family of quarks and
squarks, N3LO corrections due to top-quarks, approximate NNLO corrections
due to top squarks and electro-weak effects. Dimension-5 operators can be taken
into account. It supports various renormalization schemes
for the sbottom sector and the bottom Yukawa coupling, as well as resummation effects of
higher order tan(beta)-enhanced sbottom contributions. SusHi provides a link to FeynHiggs
for the calculation of Higgs masses in the MSSM and to 2HDMC for the 2HDM.

News

2019:

  • SusHi 1.7.0 is published! It contains various small improvements.
    Finally SusHiMi described in arXiv:1611.09308 is part
    of the newest SusHi version. Moreover a command line mode to call external
    codes was added. Have a look at the changelog for further information.
  • An online installation of SusHi is available!
  • SusHi 1.7.0 was used for the suggestion of new MSSM benchmark scenarios,
    published in arXiv:1808.07542 and arXiv:1901.05933.
    The relevant input files can be found on the "Examples" page.
  • A clarifiying remark about the convention of β-α in the 2HDM is added to the "Manual" page.
2016:
  • In arXiv:1611.09308 we study the phenomenology of Higgs production
    in the MSSM with complex parameters. The extension SusHiMi is now part of SusHi 1.7.0.
  • In arXiv:1608.02949 we study transverse momentum distributions of the Higgs in the NMSSM.
    The results and uncertainties of three different codes based on SusHi are compared.
  • MoRe-SusHi 1.1.0 with NMSSM support is now available!
  • New version of aMCSusHi allows for calculations in the NMSSM!
  • SusHi Bento (V 1.6.0) published!
2015:
  • New version of the script aMCSusHi for MadGraph5_aMC@NLO is now available.
    The manual with more information, especially on the choice of the shower scale,
    can be found here.
  • SusHi 1.5.0 calculates neutral Higgs cross sections for the 5 Higgs bosons of the NMSSM.
2014:
  • SusHi 1.4.0 is compatible with LHAPDF 6 and allows to link HiggsBounds/HiggsSignals.
  • The add-on MoRe-SusHi allows for the computation of analytically resummed
    transverse momentum distributions. A link to MadGraph is available.
  • In arXiv:1404.0327 SusHi 1.3.0 was used for precise predictions for Higgs-boson production
    in the MSSM, including a discussion of all relevant theoretical uncertainties.
    Corresponding input files can be found on the "Examples" page.
2013:
  • Starting with V 1.1.1 SusHi allows to link the code 2HDMC
    for more sophisticated considerations in the 2HDM.
  • Starting with V 1.0.2 gluon fusion and bottom-quark annihilation cross sections
    for the 2-Higgs-Doublet-Model (2HDM) can be calculated.
    The 2HDM is shortly explained on the "Manual" page.
    For example input and output files regarding recent MSSM benchmark scenarios
    we refer to the "Examples" page.
