Although <span>HiggsBounds</span> supports a LesHouches interface, this functionality is restricted so far to at most 5 neutral Higgs fields, and therefore, we don’t use it. Instead, a SPheno module generated by SARAH can create all necessary input files needed for a run of <span>HiggsBounds</span> with effective couplings (option <span>whichinput=effC</span>). To write these file, the flag 76 in the block <span>SPhenoInfo</span> in the LesHouches input file has to be set to <span>1</span>.

Unfortunately, we can not provide all information which can be used by <span>HiggsBounds</span> to check the constraints. So far, the effective couplings *H* → *γ**Z* and *H* → *g**g**Z* are not calculated by SPheno and therefore they are set to zero in the output. In addition, as already mentioned, the SPheno version created by SARAH does not include the calculations of *e*<sup>+</sup>*e*<sup>−</sup> cross sections. For this reason, also the LEP production cross section of charged Higgs fields is not available for SPheno and it sets this value also to 0 in the output. However, it is of course possible to calculate this cross section as well as all other cross sections needed for the options (<span>whichinput=hadr</span> or <span>whichinput=part</span>) of <span>HiggsBounds</span> using CalcHep , <span>Madgraph</span> or WHIZARD .
