Improving on the Pythia modelling of equal-scale multi-parton distribution functions
Oleh Fedkevych, Jonathan R. Gaunt, Seonagh Smith
Multi-parton distribution functions (mPDFs) are non-perturbative objects that are important in the prediction of multiple scattering rates at hadron colliders. In the case where th…
Heavy Flavor Jet Substructure at Lepton Colliders
Prasanna K. Dhani, Oleh Fedkevych, Andrea Ghira
We provide a detailed analysis of event-shape observables, namely the energy correlation function and jet angularity, for heavy-flavor jets produced in electron-positron collisions…
Jet substructure of light and heavy flavor jets at RHIC
Zhuoheng Yang, Oleh Fedkevych, Roli Esha
Jet substructure studies at the Large Hadron Collider have been used to constrain parton distribution functions, test perturbative QCD, measure the strong-coupling constant, and pr…
Heavy Flavour Jet Substructure
Prasanna K. Dhani, Oleh Fedkevych, Andrea Ghira +2
We present a comprehensive study of energy correlation functions and jet angularities for heavy-flavour QCD jets. In particular, we discuss the possibility of using these observabl…
Jet angularities in dijet production in proton-proton and heavy-ion collisions at RHIC
Yang-Ting Chien, Oleh Fedkevych, Daniel Reichelt +1
We study jet angularities for dijet production at the Relativistic Heavy Ion Collider (RHIC) in proton-proton (pp) and nucleus-nucleus (AA) collisions at 200 GeV nucleon-nucleon ce…
On sum rules for double and triple parton distribution functions and Pythia's model of multiple parton interactions
Oleh Fedkevych, Jonathan R. Gaunt
Multi-parton distributions in a proton, the nonperturbative quantities needed to make predictions for multiple scattering rates, are poorly constrained from theory and data and mus…
Identification of b-jets using QCD-inspired observables
Oleh Fedkevych, Charanjit K. Khosa, Simone Marzani +1
We study the issue of separating hadronic jets that contain bottom quarks (-jets) from jets featuring light partons only. We develop a novel approach to -tagging that exploit…
Phenomenology of jet angularities at the LHC
Daniel Reichelt, Simone Caletti, Oleh Fedkevych +3
We compute resummed and matched predictions for jet angularities in hadronic dijet and Z+jet events with and without grooming the candidate jets using the SoftDrop technique. Our t…
Tagging the initial-state gluon
Simone Caletti, Oleh Fedkevych, Simone Marzani +1
We study the production of an electroweak boson in association with jets, in processes where the jet with the highest transverse momentum is identified as quark-initiated. The quar…
Jet Angularities in Z+jet production at the LHC
Simone Caletti, Oleh Fedkevych, Simone Marzani +4
We present a phenomenological study of angularities measured on the highest transverse-momentum jet in LHC events that feature the associate production of a boson and one or mo…
Double parton scattering in four-jet production in proton-proton collisions at the LHC
Oleh Fedkevych, Anna Kulesza
We study the contribution from double parton scattering (DPS) to four-jet production at the LHC, both at the leading order accuracy and after incorporating the effects of QCD radia…
Four-jet double parton scattering production in proton-nucleus collisions within the PYTHIA8 framework
Oleh Fedkevych, Leif Lönnblad
We present our studies of four-jet double parton scattering production in proton-nucleus collisions within the framework of the PYTHIA8 event generator. We demonstrate that double…
