| Summary:
Searches for weakly interacting particles is one of the main goals of the
high luminosity LHC run. In this work we study the well motivated cases of
electroweakinos with mostly Wino and Bino components. We show the relevance of
squark induced t-channel production in defining the production cross section
and hence the LHC reach. Moreover, a realistic evaluation of the decay
branching ratios show a strong dependence on the sign of $mu$ and, for
negative values of $mu$, on the relative size of the ratio of $mu$ to the
gaugino masses compared with tan$beta$. Overall, unless it is kinematically
suppressed, or specific conditions are fulfilled, the Higgs decay channel is
the most significant one, and the trilepton channel becomes subdominant with
respect to final states including bottom quarks. Although the properties are
different than in the Higgsino-Bino case, also in this case the discovery reach
extends to mass values that are significantly larger than the ones probed at
current luminosities, leading to a strong motivation for the search for
electroweakinos in the high luminosity LHC run.
