CT25: the new generation of CTEQ-TEA PDFs
Alim Ablat, Daniel Adamiak, Aurore Courtoy +12
This contribution reviews CT25, a new generation of CTEQ--TEA parton distribution functions (PDFs) for precision QCD. With its first member sets released in 2025, the CT25 family a…
Constraining Proton Spin at Small with Valence Quark Model
Yossathorn Tawabutr, Daniel Adamiak, Heikki Mäntysaari
Recently, a global analysis has been performed for longitudinal spin asymmetries in polarized deep inelastic scattering (DIS) processes, combining the polarized valence quark model…
First study of polarized proton-proton scattering with small- helicity evolution
Daniel Adamiak, Nicholas Baldonado, Yuri V. Kovchegov +7
We perform a phenomenological study of helicity-dependent parton distribution functions (PDFs) using small- helicity evolution equations, incorporating for the first time single…
Proton spin from small- with constraints from the valence quark model
Daniel Adamiak, Heikki Mäntysaari, Yossathorn Tawabutr
We apply the valence quark model recently calculated for polarized proton to constrain the non-perturbative initial condition for the small- helicity evolution. The remaining fr…
Kernel methods for evolution of generalized parton distributions
A. Freese, D. Adamiak, I. Cloët +4
Generalized parton distributions (GPDs) characterize the 3-dimensional structure of hadrons, combining information about their internal quark and gluon longitudinal momentum distri…
Small- Asymptotics of the Leading-Twist Flavor Singlet Quark TMDs
M. Gabriel Santiago, Daniel Adamiak, Yossathorn Tawabutr
In this paper, we investigate the small- behavior of the flavor-singlet, leading-twist quark Transverse Momentum Dependent parton distribution functions (TMDs) using the Light-C…
