PanopTag: Simultaneously Tagging All Jets in a Particle Collision Event
Umar Sohail Qureshi, Brendon Bullard, Ariel Schwartzman
Jet tagging, identifying the origin of jets produced in particle collisions, is a critical classification task in high-energy physics. Despite the revolutionary impact of deep lear…
Deep Image Reconstruction for Background Subtraction in Heavy-Ion Collisions
Umar Sohail Qureshi, Raghav Kunnawalkam Elayavalli
Jet reconstruction in an ultra-relativistic heavy-ion collision suffers from a notoriously large, fluctuating thermal background. Traditional background subtraction methods struggl…
Probing a Quarkophobic at the High-Luminosity LHC via Vector Boson Fusion and Lorentz-Equivariant Point Cloud Learning
U. S. Qureshi, A. Gurrola, J. D. Ruiz-Álvarez
The addition of a heavy charged vector gauge boson to the Standard Model (SM) with negligible quark couplings ("quarkophobic") and triple gauge couplings can…
Model-Agnostic Tagging of Quenched Jets in Heavy-Ion Collisions
Umar Sohail Qureshi, Raghav Kunnawalkam Elayavalli
Measurements of jet substructure in ultra-relativistic heavy-ion collisions indicate that interactions with the quark-gluon plasma quench the jet showering process. Modern data-dri…
A New Herwig7 Underlying Event Tune: from RHIC to LHC Energies
Umar Sohail Qureshi, Raghav Kunnawalkam Elayavalli, Luke Mozarsky +2
We present parameter sets corresponding to new underlying event tunes for the Herwig7.3 Monte Carlo event generator. The existing Herwig tunes are in good agreement with LHC data,…
Probing Compressed Mass Spectrum Supersymmetry at the LHC with the Vector Boson Fusion Topology
Umar Sohail Qureshi, Alfredo Gurrola, Andres Flórez
We present a phenomenology study probing pair production of supersymmetric charginos and neutralinos ("electroweakinos") with the vector boson fusion (VBF) topology in proton-proto…
