Probing Light Scalars and Vector-like Quarks at the High-Luminosity LHC
Umar Sohail Qureshi, Andres Flórez, Alfredo Gurrola +1
A model based on a extension of the Standard Model can address the mass hierarchy between generations of fermions, explain thermal dark matter abundance, and the muo…
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…
