Attendance: about 30 people connected all the time. Peak at 36.
- Coordination of exotic decay work with people of the LHC HXSWG working on SUSY for NMSSM/MSSM benchmarks (contacts: Sven Heinemeyer, Maggie Muehlleitner) and with the Extended Scalar group (contact: Heather Logan)
- Some topics raised by Petriello's talk:
- trigger issues for Higgs decays to mesons (slide 14 of his talk). Need triggers for gamma + ( rho, phi, omega): doable? Needs to be implemented if so.
- action for working group: facilitate interaction with Pythia authors to implement angular distributions in exclusive mesonic decays
- Should we search specifically for a 125 GeV SM Higgs decaying exotically or should we keep the mass as a free parameter? Viewed as high priority decision for experimentalists. Suggestion: one working point should always be the 125 GeV Higgs. If not onerous for a given analysis, it would additionally be important to extend the search range to both heavier and lighter masses to broaden sensitivity to exotic states that may be mixing with the SM Higgs or decays with resonances plus missing energy.
- Status of Run I data at this point? Current priority is the development of the triggers at Run II. Recent CMS search for h \to gamma + MET needed parked data. How easy to go back to old datasets in the future?
- VBF trigger for 2016?
- For searches like h->aa->4mu and h->aa->2tau 2mu, it would be important to go to higher and lower pseudoscalar masses and not only to restrict to m_a< few GeV
- Importance of the h->aa->4b search. Higgs produced in association with a W boson?
- Ian Low suggests phrasing working group recommendations in terms of a set of fiducial observables.
- Matt Strassler: the big survey document (http://arxiv.org/pdf/1312.4992.pdf) provides benchmarks and prioritization for Higgs decays with up to 4 visible partons. But experimentalists are still asking for benchmarks and prioritization. What is lacking in the big document from an experimental point of view?
- Need for benchmark development at high multiplicity and with missing energy. Currently the largest blind spot in coverage is partly-invisible decays.
