Constraining new physics with searches for long-lived particles: Implementation into SModelS

Constraining new physics with searches for long-lived particles: Implementation into SModelS

We present the implementation of heavy stable charge particle (HSCP) and R-hadron signatures into SModelSv1.2. We include simplified-model results from the 8 and 13 TeV LHC and demonstrate their impact on two new physics scenarios motivated by dark matter: the inert doublet model and a gravitino dar...
