| - | Interested: | + | ====== Higgs Self Coupling and di-Higgs ====== |
| - | - V phi, with phi -> gamma gamma, what does the LHC can say? | ||
| - | bounds from LEP. what is the LHC capability? | + | Interested people: Fabio Maltoni, Minho Son, José Zurita, Benjamin Fuks, Ramona Groeber, Alexandra Carvalho ... |
| - | + | \\ | |
| - | bounds from H coupling measurements to ZZ and EWPT | + | \\ |
| - | + | We will discuss the resonant production together with the "Interference" group. | |
| - | - Complementarity with phi single production together with a ISR | + | \\ |
| - | + | \\ | |
| - | - h->ss->SM (eventually scalars with different masses h-> s1s2) | + | Idea so far: Parameterise resonant production in terms of 5 parameters. Check when only a subset is necessary, check under which circumstances there is sizeable interference with box and 125 GeV Higgs exchange. |
| - | what are the holes? | + | \\ |
| - | + | \\ | |
| - | * signatures with resolved/not resolved photons: 2b 2gamma, 4 gamma, s Z with s->gamma gamma | + | Further possible discussion points for the kick-off meeting:\\ |
| - | * decays involving missing energy: h->chi1 chi2 with chi1 invisible | + | 1.) status what kind of analysis ongoing?\\ |
| - | * s with displaced decays. Role of the LHCb | + | 2.) resonant production searches at the moment in terms of benchmarks, how to benchmark, generalisation, interference?\\ |
| + | 3.) combination different final states \\ | ||
| + | 4.) Scenarios that allow us to observe new physics for first time in HH production?\\ | ||
| + | 5.) in EFT analysis BR remain SM-like, can be improved on that? \\ | ||
| + | 6.) larger bounds on trilinear Higgs self-coupling can be usually obtained in negative range, but most models have positive deviation, which models have negative deviation?\\ | ||
