Transverse-spin dependent energy-energy correlators in proton-proton collisions within the dihadron fragmentation framework
Zhong-Bo Kang, Andreas Metz, Daniel Pitonyak +1
We calculate energy-energy correlations for two hadrons produced inside a jet in transversely polarized proton-proton collisions. We make numerical predictions based on a simple mo…
Simplified approach to extracting nucleon transversity in collinear factorization using near-side energy-energy correlators
Zhong-Bo Kang, Andreas Metz, Daniel Pitonyak +1
We develop a novel strategy for accessing the transversity parton distribution function (PDF) of the nucleon within collinear factorization using near-side energy-energy correlator…
AI-assisted modeling and Bayesian inference of unpolarized quark transverse momentum distributions from Drell-Yan data
Zhong-Bo Kang, Luke Sellers, Congyue Zhang +1
We present an extraction of unpolarized quark transverse-momentum-dependent parton distribution functions (TMD PDFs) from Drell-Yan data within a Bayesian inference framework, inco…
Dihadron fragmentation framework for near-side energy-energy correlators
Zhong-Bo Kang, Andreas Metz, Daniel Pitonyak +1
We establish an approach to analyze the free hadron and transition (nonperturbative) regions of near-side energy-energy correlators (EECs) based on dihadron fragmentation functions…
Determination of the strong coupling constant and the Collins-Soper kernel from the energy-energy correlator in collisions
Zhong-Bo Kang, Jani Penttala, Congyue Zhang
We have conducted the first simultaneous global fit of the strong coupling constant and the Collins-Soper (CS) kernel using the energy-energy correlators (EEC) of $e^{+} e^{…
