LHCspin: a Polarized Gas Target for LHC
A. Accardi, A. Bacchetta, L. Barion +90
The goal of the LHCspin project is to develop innovative solutions for measuring the 3D structure of nucleons in high-energy polarized fixed-target collisions at LHC, exploring new…
TMD phenomenology motivated by nonperturbative structures
Ted Rogers, Fatma Aslan, Mariaelena Boglione +3
This talk summarized work done recently to organize the steps for implementing TMD phenomenology in a way optimized for contexts where the extraction and interpretation of hadronic…
Simultaneous reweighting of Transverse Momentum Dependent distributions
Mariaelena Boglione, Umberto D'Alesio, Carlo Flore +3
The Bayesian reweighting procedure is extended to the case of multiple independent extractions of transverse momentum dependent parton distributions (TMDs). By exploiting the data…
Phenomenology of TMD parton distributions in Drell-Yan and boson production in a hadron structure oriented approach
F. Aslan, M. Boglione, J. O. Gonzalez-Hernandez +3
We present a first practical implementation of a recently proposed hadron structure oriented (HSO) approach to TMD phenomenology applied to Drell-Yan like processes, including lept…
Proof of principle for a self-governing prediction and forecasting reward algorithm
J. O. Gonzalez-Hernandez, Jonathan Marino, Ted Rogers +1
We use Monte Carlo techniques to simulate an organized prediction competition between a group of a scientific experts acting under the influence of a ``self-governing'' prediction…
The resolution to the problem of consistent large transverse momentum in TMDs
J. O. Gonzalez-Hernandez, T. Rainaldi, T. C. Rogers
Parametrizing TMD parton densities and fragmentation functions in ways that consistently match their large transverse momentum behavior in standard collinear factorization has rema…
Basics of factorization in a scalar Yukawa field theory

A new formalism for the factorization of the cross section for single hadron production in annihilations, differential in , and thrust, is applied to the phenom…
Phenomenological extraction of a universal TMD fragmentation function from single hadron production in annihilations
M. Boglione, J. O. Gonzalez-Hernandez, A. Simonelli
Factorizing the cross section for single hadron production in annihilations, differential in , and thrust, is a highly non trivial task. We have devised a facto…
Reweighting the quark Sivers function with STAR jet data
Carlo Flore, Maria Elena Boglione, Umberto D'Alesio +3
The Bayesian reweighting procedure is applied for the first time to a TMD distribution, the quark Sivers function extracted from SIDIS data. By exploiting the recent published sing…
Science Requirements and Detector Concepts for the Electron-Ion Collider: EIC Yellow Report
R. Abdul Khalek, A. Accardi, J. Adam +410
This report describes the physics case, the resulting detector requirements, and the evolving detector concepts for the experimental program at the Electron-Ion Collider (EIC). The…
Reweighting the Sivers function with jet data from STAR
Mariaelena Boglione, Umberto D'Alesio, Carlo Flore +3
The reweighting procedure that using Bayesian statistics incorporates the information contained in a new data set, without the need of re-fitting, is applied to the quark Sivers fu…
