Abstract
Searches for supersymmetry at the ATLAS and CMS experiments are discussed. The analyzed data were recorded at the Large Hadron Collider in 2015 at a center of mass energy of 13 TeV and correspond to an integrated luminosity of up to 3 fb-1 per experiment. No physics beyond the standard model has been observed. Different inclusive and specialized analysis strategies targeting various signal scenarios are introduced. The analysis sensitivities are summarized as exclusion contours for different simplified signal model spectra and compared to the previous 8 TeV results.
Highlights
After the long shutdown, the Large Hadron Collider (LHC) at CERN has delivered in 2015 the first proton-proton collision data at a center of mass energy of 13 TeV
The ATLAS and CMS collaborations have searched in the first 3 fb−1 of data collected at 13 TeV for signs of supersymmetry
The observed data are in good agreement with the expectations from standard model processes
Summary
The Large Hadron Collider (LHC) at CERN has delivered in 2015 the first proton-proton collision data at a center of mass energy of 13 TeV. The sensitivity to signals of new physics scenarios already matches or exceeds the results obtained on the 8 TeV data set collected until 2012 corresponding to up to 20 fb−1. Supersymmetry (SUSY) [5] is a very popular theory for physics beyond the standard model, developed since the 1970s as an extension of the Poincaré symmetry. SUSY links each particle of the standard model (SM) with a supersymmetric partner with equal properties, except for the spin which differs by 1/2 and the mass. In order to interpret the analyis results generally simplified model spectra (SMS) [8, 9] are used, which allow to model individual decay topologies through effective on-shell theories, involving only the masses of typically two SUSY particles as free parameters. Different strategies for searches for supersymmetry are discussed, from very inclusive searches for strong production in hadronic final states to more specific signatures such as dilepton resonances and kinematic edges are discussed in the following
