Cannot generate Higgs to bbtautau in RS/2HDM models

Asked by Nikolina.Ilic@cern.ch on 2015-07-03

 Hello,

I try generating the process p p > hh, (hh > h h, h > b b~, h > ta+ ta-) and selecting the Randall-Sundrum and 2HDM models, but it does not find the processes. What am I doing wrong?

Thank you!

Hello Nikolina,
                                I think in 2HDM, pp > hh is not possible at tree level. if you want at one loop level, please see http://arxiv.org/abs/1507.00020.

Hello,

Why isn't the Randall-Sundrum one working then? I took the generate line from someone running this model locally for whom it worked.

Thank you!

    Hello Nikolina,
                                      for RS the correct syntax should be

generate p p > h h , ( h > b b~ , h > ta+ ta- )

Hope, now it works for you.

Shiba

Hello,

Yes this worked, thank you!

Ah no wait, I got the error below:
