We present an analysis of new physics searches in with missing energy final states at the Large Hadron Collider considering (where ) a…
Probing the sensitivity of semi-visible jets to current LHC measurements using the CONTUR toolkit
Andy Buckley, Jon Butterworth, Louie Corpe +5
Semi-visible jets arise from a hypothetical, strongly interacting ``dark sector'' -- a dark counterpart of quantum chromodynamics whose partial decays back to Standard Model partic…
Effect of new jet substructure measurements on Pythia8 tunes
Deepak Kar, Pratixan Sarmah
This study used the recent ATLAS jet substructure measurements to see if any improvements can be made to the commonly used Pythia8 Monash and A14 tunes.
Jet Substructure at the Large Hadron Collider: Experimental Review

Phenomenology of additional scalar bosons at the LHC
Mukesh Kumar, Stefan von Buddenbrock, Nabarun Chakrabarty +7
The confirmation of the Higgs boson in Run I data at the Large Hadron Collider (LHC) and the excesses in recent Run II data suggest scenarios beyond the Standard Model (SM). We pur…

Jets and Jet Substructure at Future Colliders
Ben Nachman, Salvatore Rappoccio, Nhan Tran +24

Systematics of quark/gluon tagging
Philippe Gras, Stefan Höche, Deepak Kar +7
By measuring the substructure of a jet, one can assign it a "quark" or "gluon" tag. In the eikonal (double-logarithmic) limit, quark/gluon discrimination is determined solely by th…
Exploring Jet Substructure in Semi-visible jets
Deepak Kar, Sukanya Sinha
Semi-visible jets arise in strongly interacting dark sectors, where parton evolution includes dark sector emissions, resulting in jets overlapping with missing transverse momentum.…
