+ | === To be discussed Thursday 10:30-12:00: === | ||
+ | |||
+ | == STXS: == | ||
+ | * presentation of the experimental results (which information to make public and how) | ||
+ | * interpretation of STXS results (what is needed from experiment and theory for a simple interpretations such as STXS -> production mode signal strength by someone outside of the experiments) | ||
+ | * merging of STXS bins (in case of no experimental sensitivity to a given bin, and/or large correlations. Do we want to propose a "stage-0.5"?) | ||
+ | |||
+ | ==Differential xs: == | ||
+ | * additional variables of interest for differential measurements | ||
+ | * how to estimate uncertainties related to model dependence (assuming SM in the calculation of acceptance corrections) | ||
+ | |||
+ | |||
+ | ---- | ||
+ | |||
+ | |||
+ | === To be discussed Thursday 16:30-18:30: === | ||
+ | |||
+ | == STXS: == | ||
+ | * parametrization of theory uncertainties for VBF and VH (identification of uncorrelated sources in the predictions) | ||
+ | * treatment of gg->Z(->qq)H (currently this is absorbed into gg->H, should it stay like this? should we define dedicated STXS bins?) | ||
+ | * ttH: introduction of dedicated STXS bins? | ||
