An event generator for SM Higgs decay into 4 charged leptons at NLOPS EW accuracy
Hto4l is an event generator for the SM Higgs decay into 4 charged leptons up to NLOPS electroweak
accuracy and in presence of dimension-6 operators. It can be used
either for the calculation of the partial width of the Higgs boson in
the H -> Z(*)Z(*) ->
4l channels or in association with any event generator which provides events for
the Higgs production in the Les Houches standard format.
The latest version of Hto4l is 2.02 and can
be downloaded here. A
more detailed description of the code can be found in the
file. The main improvement of v2.x is the possibility of
generating Higgs decay events in presence
of dimension-six operators. The user can choose among three bases: the Warsaw basis, the SILH basis and
the so-called Higgs basis.
06 (2015) 023 and JHEP 1801 (2018) 096 for phenomenological studies and citing the code.
Stay tuned on this page for updates and bug fixes.
We'd appreciate if you could send an e-mail to one of the
authors after downloading the generator,
so that we can inform you about updates of the code, publications, etc.
