Cross section for $\firstcharg\secondchi$ production at $\sqrt{s} = 13\TeV$ versus the wino mass, calculated to NLO accuracy in QCD with \textsc{Resummino}~\cite{Fuks:2013vua}. The \firstcharg and \secondchi are assumed to be mass-degenerate winos. The various curves show different assumptions on the masses of the squarks and gluinos, as described in the legend. The green band shows the theoretical uncertainty in the cross section calculation, from the variation of renormalization and factorization scales as well as parton density functions, for the 100\TeV squark and gluino mass assumption.

Distributions of \ptmiss for two representative signal points in the \wz corridor as well as the expected SM background for $\HT < 100$ (left) and $\geq 200\GeV$ (right). The mass values for the signal points are given as $(\msecondchi / \mfirstchi)$ in \GeV. For larger values of \HT, the shape difference between signal and background becomes more pronounced due to the presence of \firstchi\ LSPs with large Lorentz boost.
