Implementation of the ATLAS-SUSY-2019-08 analysis in the MadAnalysis 5 framework (electroweakinos with a Higgs decay into a $b\bar b$ pair, one lepton and missing transverse energy; 139 fb$^{−1}$)
/ Goodsell, Mark D (Paris, LPTHE)
This is the validation note for the recast in MadAnalysis 5 of the study ATLAS-SUSY-2019-08: a search for direct production of electroweakinos in final states with one lepton, missing transverse momentum and a Higgs boson decaying into two b-jets in pp collisions at s = 13 TeV with the ATLAS detector, using an integrated luminosity of 139 fb−1. The recasting code is validated against cutflows and expected signal events for benchmark scenarios, and the exclusion limits are reproduced for a simplified supersymmetric electroweakino sector consisting of a degenerate wino decaying to a light stable bino..

Recasting the CMS Disappearing Track search
/ Goodsell, Mark Dayvon (speaker) (Univ. P. et Marie Curie Paris VI (FR))
The CMS disappearing track search using the full Run 2 data (2004.05153) has the potential to place the strongest limits on many scenarios, such as minimal dark matter and especially supersymmetric models where the electroweakino mass splittings become small enough the the charginos are long-lived. I shall report on progress producing codes to recast this analysis..

Higgs-mass predictions in the MSSM and beyond

(Korea U. ; Cornell U., LEPP ; Toronto U.) et al.
Predictions for the Higgs masses are a distinctive feature of supersymmetric extensions of the Standard Model, where they play a crucial role in constraining the parameter space. The discovery of a Higgs boson and the remarkably precise measurement of its mass at the LHC have spurred new efforts aimed at improving the accuracy of the theoretical predictions for the Higgs masses in supersymmetric models.

/LHC Reinterpretation Forum
We report on the status of efforts to improve the reinterpretation of searches and measurements at the LHC in terms of models for new physics, in the context of the LHC Reinterpretation Forum. We detail current experimental offerings in direct searches for new particles, measurements, technical implementations and Open Data, and provide a set of recommendations for further improving the presentation of LHC results in order to better enable reinterpretation in the future.

Report from Working Group 1 : Standard Model Physics at the HL-LHC and HE-LHC
/ Azzi, P. (INFN, Padua) ; Farry, S. (Liverpool U.) ; Nason, P. (INFN, Milan Bicocca ; Milan Bicocca U.) ; Tricoli, A. (Brookhaven Natl. Lab.) ; Zeppenfeld, D. (KIT, Karlsruhe, TP) ; Abdul Khalek, R.

The successful operation of the Large Hadron Collider (LHC) and the excellent performance of the ATLAS, CMS, LHCb and ALICE detectors in Run-1 and Run-2 with $pp$ collisions at center-of-mass energies of 7, 8 and 13 TeV as well as the giant leap in precision calculations and modeling of fundamental interactions at hadron colliders have allowed an extraordinary breadth of physics studies including precision measurements of a variety physics processes. The LHC results have so far confirmed the validity of the Standard Model of particle physics up to unprecedented energy scales and with great precision in the sectors of strong and electroweak interactions as well as flavour physics, for instance in top quark physics.

Precision tools and models to narrow in on the 750 GeV diphoton resonance

The hints for a new resonance at 750 GeV from ATLAS and CMS have triggered a significant amount of attention. Since the simplest extensions of the standard model cannot accommodate the observation, many alternatives have been considered to explain the excess. [...]
