SUSY Production at the LHC without Missing P_T

TL;DR

This paper explores a rare SUSY production process at the LHC where chargino decays produce W bosons and neutralinos without missing P_T, highlighting a potential excess in W production cross-section.

Contribution

It introduces a novel SUSY event signature with no missing P_T and analyzes its likelihood within the MSSM near the EWSB boundary.

Findings

Possible W production cross-section excess of a few percent.

Identification of SUSY events with no missing P_T at the LHC.

Parameter space region where these events are probable.

Abstract

We consider relatively rare events of SUSY production at the LHC without missing $p_T$. Namely, we discuss the chargino production with further decay into the W-boson and the neutralino when the masses of chargino and neutralino differ by 80-90 GeV. In this case, in the final state one has two Ws and missing $E_T$ but no missing $P_T$. The produced neutralinos are just busted along Ws. Within the MSSM such events are quite probable in the region of parameter space close to the EWSB border line. The excess in the W production cross-section may achieve a few \%.
