EXOTIC PRODUCTION AND EXTENDED HIGGS SECTORS

¡ Results both model independent and MSSM benchmark scenarios

§ No hints of extended Higgs Sector yet

¡ Moving to 2015, and taking into account the picture that Run I provides

§ What’s the theoretical wish list on this channel for 2015? § Any missing deliverables from the experiments?

ALIGNMENT VS DECOUPLING:

DI-HIGGS RESONANCE

¡ Important channel that is well-motivated from the “alignment limit.” ¡ Both scalar->hh and spin-2

• > hh are searched for

¡ Combination of CMS and ATLAS already a feature of many Run1 results ¡ Propects for combination in the context of today results, for instance in hh searches?

How much is limiting the narrow width approximation? Is the vbf production mechanism worth to be investigated?

RARE HADRONIC HIGGS DECAYS

¡ Echoing the request in the ATLAS talk: lack of reliable computations to close the gap between 160 and 200 GeV ¡ In a more general way: what are the prospects for new computations?
