Supersymmetry is a natural solution to many phenomena left unexplained by the Standard Model, such as the hierarchy problem that arises due to quantum corrections to the Higgs boson mass. Models which allow for R-parity violation (RPV) are favored by recent lepton flavor anomalies and can provide insight into the neutrino mixing hierarchy. The direct pair ...
Higgsinos with compressed mass spectra and masses near the electroweak scale are highly motivated by naturalness considerations and consistent with cosmological evidence, yet still poorly constrained by the LHC. This search will focus on the neutralino mass splitting $Δm=m_{{\widetilde{χ}}_2^0}-m_{{\widetilde{χ}}_1^0}$, in the region of 0.3~2 GeV, which has not been covered by ATLAS analyses...
Higgsinos with masses near the electroweak scale and within a compressed mass spectrum represent a poorly constrained region of the SUSY parameter space that is nonetheless strongly motivated by both naturalness and dark matter considerations. In this talk we develop a search for higgsinos in compressed scenarios by studying the production of the second lightest neutralino ($\tilde{\chi}^0_2$)...
