Hunting the Unseen: Deep Learning Analysis for Semi-Visible Jet Tagging
Miguel A. Avendaño-Bernal, Srinandan Dasmahapatra, Ahmed Hammad +4
Semi-Visible Jets (SVJs) constitute a distinctive collider signature of strongly interacting dark sectors, embedding Dark Matter candidates, wherein jets contain both visible Stand…

Alexander Belyaev, Manimala Chakraborti, Claire Shepherd-Themistocleous +1
We perform a collider study of a novel multilepton signature arising from pair production of heavy vector-like leptons followed by cascade decays through a dark sector. In the muon…

A smoking gun signature of the 3HDM
A. Dey, V. Keus, S. Moretti +1
We analyse new signals of a 3-Higgs Doublet Model (3HDM) at the Large Hadron Collider (LHC) where only one doublet acquires a Vacuum Expectation Value (VEV), preserving a par…
Searching for in the 2HDM Type-I at the LHC
A. Arhrib, S. Moretti, S. Semlali +3
Unlike other realisations of the 2-Higgs Doublet Model (2HDM), the so-called Type-I allows for a very light Higgs boson spectrum. Specifically, herein, the heaviest of the two CP-e…
Re-evaluating Jet Reconstruction Techniques for New Higgs Boson Searches
Amit Chakraborty, Srinandan Dasmahapatra, Henry Day-Hall +5
The ultimate motivation of our study is to look for signs of physics beyond the Standard Model (BSM). We investigate whether different jet clustering techniques might be more or le…

We present a reinterpretation study of existing results from the CMS Collaboration, specifically, searches for light Beyond the Standard Model (BSM) Higgs pairs produced in the cha…
Spectral Clustering for Jet Physics
G. Cerro, S. Dasmahapatra, H. A. Day-Hall +3
We present a new approach to jet definition alternative to clustering methods, such as the anti- scheme, that exploit kinematic data directly. Instead the new method uses kine…
Extraction of neutrino Yukawa parameters from displaced vertices of sneutrinos
Amit Chakraborty, Stefano Moretti, Claire H. Shepherd-Themistocleous +1
We study displaced signatures of sneutrino pairs potentially emerging at the Large Hadron Collider (LHC) in a Next-to-Minimal Supersymmetric Standard Model supplemented with right-…
Revisiting Jet Clustering Algorithms for New Higgs Boson Searches in Hadronic Final States

We assess the performance of different jet-clustering algorithms, in the presence of different resolution parameters and reconstruction procedures, in resolving fully hadronic fina…
Exploring neutrino physics through sneutrinos
Stefano Moretti, Claire Shepherd-Themistocleous, Harri Waltari
Supersymmetry relates neutrinos with their superpartners, sneutrinos. Unlike neutrinos, sneutrinos may decay visibly in colliders. We discuss how we could get information from neut…

Di-lepton searches for Beyond the Standard Model (BSM) Z' bosons that rely on the analysis of the Breit-Wigner (BW) line shape are appropriate in the case of narrow resonances, but…

Status and discovery prospects for light pseudoscalars in the NMSSM
Robin Aggleton, Daniele Barducci, Nils-Erik Bomark +2
While most BSM searches at the LHC focus on heavy new states, the NMSSM contains the possibility of new light states that have escaped detection due to their singlet nature. Here w…
