4. Make more from your BSM searches : making unfolded measurements in control regions for generator tuning and re-interpretation

Louie Dartmoor Corpe (University of London (GB))

Is a new approach is needed to fully exploit the data provided by the LHC?
As the LHC begins long shutdown 2, despite hundreds of dedicated searches, there has been no sign of new physics. In these searches, much effort is put into understanding the control regions, but this information is almost never made public, and is therefore lost to posterity. In this talk, I will argue for a new...

35. Monte Carlo simulations of long-lived particles

Beyond Standard Model (BSM) scenarios often involve particles with significantly longer lifetimes compared to the particles in the Standard Model. Reliable Monte Carlo tools for simulation of processes involving such long-lived particles (LLPs) are essential for BSM searches and a variety of frameworks already exists (such as MadGraph accompanied by MadSpin, to name a few).

However, a fully...

18. HEPLike - tool for experimental likelihood

Marcin Chrzaszcz (CERN)

03/04/2019, 10:00

We will present a software called HEPLike, which can be used to share the likelihood functions of experimental measurements in HEP community. It uses YAML file to encode the experimental measurements and constructs proper likelihood functions. It can be interfaced with global fitting programs. The YAML files can be easily exchanged inside the community, allowing for more direct comparison of...

7. Discovering and characterising new physics with detector-corrected data

Darren Price (University of Manchester (GB))

03/04/2019, 11:00

I will review detector-corrected measurements that have recently been made at the LHC with the aim of allowing reinterpretation for new physics searches. I will discuss new proof-of-concept measurements designed with searches for and measurement of new phenomena in mind, new results characterising anomalous Higgs boson interactions, and effective field theory interpretations of electroweak...

2. Investigating electroweak SUSY at the LHC with GAMBIT

Anders Kvellestad (Imperial College London)

03/04/2019, 11:25

I will present the latest work on electroweak supersymmetry from the GAMBIT collaboration. With GAMBIT we have performed a large-scale fit of the electroweakino (neutralino and chargino) sector of the MSSM. The fit incorporates simulations of several recent ATLAS and CMS SUSY searches, in addition to constraints from SUSY searches at LEP and the invisible decay widths of the Z and Higgs...

15. DarkCast: recasting dark-photon searches

Yotam Soreq (CERN)

03/04/2019, 11:50

Searches for dark photons provide serendipitous discovery potential for other types of vector particles. We develop a framework for recasting dark photon searches to obtain constraints on more general theories - DarkCast.The framework includes a data-driven method for determining hadronic decay rates.
DarkCase can be used to any massive gauge boson with vector couplings to the Standard Model...
