| + | The process bbA, A->tautau might have very large cross-section (~ 100 pb) in 2HDM Type II in so called "wrong sign Yukawa coupling scenario"[[http://arxiv.org/abs/1412.3385|arXiv:1412.3385]]. It motivated CMS analyses with tautau and mumu final state | ||
| + | which have the similar sensitivity. The tautau analysis is completed and mumu analysis is going to be completed in June. The analyses select events with single b-tagging. The remaining question to be addressed in Les Houches is contribution of gg->A process in the b-tag. event category. In wrong sign scenario it can be 10 time larger than | ||
| + | bbA. The parton level analysis is running on b-loop produced gg->bbA events for two generation setups: with bb pair from gluon splitting by PY8 shower with with full LO ME b-loop produced gg->bbA. The full LE ME events are produced by Olivier Mattelaer with MG5_aMC@NLO. For 1st approach, g->bb from shower the NLO generators POWHEG and MG5_aMC@NLO are used with PY8 showering. | ||
