Explanation of Contur plot format The plots have two sections. * The top shows the measurement (black point with error bars) compared to the sum of the measurement plus any contribution from the BSM scenario under consideration (red histogram). *

Getting ready * Getting ready: Tools & MCs topics: Here, first circular about Tools & MCs topics. Discussion sessions on these topics will be organized as needed. Some suggested discussion topics: * Uncertainties in HEP event generators: Monte Carlo Event Generators come with a host of perturbative (PU) and non-perturbative (NPU) uncertainties. If PU and NPU are correlated, can we find recipes that do not underestimate the uncertainties, while at the same time not being overly conservati…
