1. Revisiting the LHC Constraints on Gauge-Mediated Supersymmetry Breaking Scenarios

We revisit Gauge Mediated SUSY Breaking (GMSB) scenarios in the context of LHC data. The ATLAS mono-photon search at 139 inverse femtobarn integrated luminosity at the 13 TeV LHC, in the context of a simplified General Gauge Mediation (GGM) scenario (which is a phenomenological version of GMSB with an agnostic approach to the nature of the hidden sector), relies on assumptions that do not hold...

14. Revisiting Universal Extra-Dimension Model with Gravity Mediated Decays

We explore the collider phenomenology of the fat-brane realization of the Minimal Universal Extra Dimension (mUED) model, where Standard Model (SM) fields propagate in a small extra dimension while gravity accesses additional large extra dimensions. This configuration allows for gravity-mediated decay (GMD) of Kaluza-Klein (KK) particles, resulting in unique final states with hard photons,...

26. Sensitivity of LHC searches to Inert Doublet Model via Recasting with CheckMATE2

Recasting is an extremely powerful tool to derive limits on new physics models. With so many NP models at our disposal, recasting makes it easy to use the limits derived on certain models by experimental searches, to constrain any model of our choice. However, this method can fail, if the model of our interest not only differs from the one it is being recasted from, in terms of event rates,...

32. New Higgses at the electroweak scale

Statistically significant di-photon excess at 95 GeV (>3sigma) and 152 GeV (>4sigma) have been observed. Furthermore, strong tensions exist between the SM predictions and measurements of W and top-like signatures at the LHC. I discuss the status of these anomalies and detail the reinterpretation studies done on the relevant ATLAS searches to assess how the excesses can be related to new...

3. An MCMC analysis to probe trilinear RPV SUSY scenarios and possible LHC signatures

Arpita Mondal (Indian Institute of Technology Patna)

We probe the trilinear R-parity violating (RPV) supersymmetric (SUSY) scenarios with specific non-zero interactions in the light of neutrino oscillation, Higgs, and flavor observables. We attempt to fit the set of observables using a state-of-the-art Markov Chain Monte Carlo (MCMC) set-up and study its impact on the model parameter space. Our main objective is to constrain the trilinear...
