In this talk, we will give a brief overview of CheckMATE 2 and discuss recent developments. In particular, we present the implementation of four types of long-lived particle searches, viz. displaced leptons, disappearing track, displaced vertex with either muons or with missing transverse energy, and heavy charged tracks. These four categories cover the signatures of a large range

The new developments in SModelS, an automated tool enabling the fast interpretation of simplified model results from the LHC, make it possible to include a wide range of constraints for long-lived particles and treat them at the same footing as the constraints from prompt searches. We present these new features of SModelS v2.x and the new experimental analyses included in its database. To...
In this contribution, we report about the latest developments in MadAnalysis 5 relevant for recasting studies. The recasting interface has been extended to accommodate signal region combinations through full and simplified likelihoods which allow users to calculate more accurate global exclusion limits for new physics. Additionally, we will briefly introduce the new recasting capabilities of...
A trio of automated collider event analysis tools are described and demonstrated. AEACuS interfaces with the standard MadGraph/MadEvent, Pythia, and Delphes simulation chain, via the Root file output. An extensive algorithm library facilitates the computation of standard collider event variables and the transformation of object groups (including jet clustering and substructure analysis)....
The analysis framework developed for searches of the Higgs boson decaying into two muons with CMS detector is presented. The framework showcases the tools for columnar analysis in HEP (coffea package) as well as an efficient job distribution with state of the art scheduling tools (Dask, Apache Spark). The performance of the framework and parallelization of job processing has been studied using...
CONTUR is a tool which automatically injects signal events into the phase space of O(100) of the O(1000) ATLAS, CMS and LHCb measurements preserved in Rivet+HEPData, to check whether the distortions would have been visible beyond measured uncertainties, and identify the ruled out/open parameter space. This approach has shown itself to be very successful, with several results applying the...
