SModelS v1.2: long-lived particles, combination of signal regions, and other novelties

Understand

SModelS is an automatised tool enabling the fast interpretation of simplified model results from the LHC within any model of new physics respecting a $\mathbb{Z}_2$ symmetry.

• With the version 1.2 we announce several new features.
• First, previous versions were restricted to missing energy signatures and assumed prompt decays within each decay chain.
• SModelS v1.2 considers the lifetime of each $\mathbb{Z}_2$-odd particle and appropriately takes into account missing energy, heavy stable charge particle and R-hadron signatures.
