+ | We will discuss the resonant production together with the "Interference" group. | ||
+ | \\ | ||
+ | \\ | ||
+ | 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. | ||
+ | \\ | ||
+ | A reference for the singlet model and the interferences is | ||
+ | https://arxiv.org/pdf/1508.05397.pdf | ||
+ | \\ | ||
+ | \\ | ||
+ | Further possible discussion points for the kick-off meeting:\\ | ||
+ | 1.) status what kind of analysis ongoing?\\ | ||
+ | 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?\\ |
