Pion Valence Structure at Intermediate x in the Residual Field Approach
Joseph Maerovitz, Christopher Leon, Misak Sargsian
We calculate the valence parton distribution function~(PDF) of pion, within the theoretical approach based on spectral function representation of valence quarks in the pion. In thi…

We outline the physics opportunities provided by the Electron Ion Collider (EIC). These include the study of the parton structure of the nucleon and nuclei, the onset of gluon satu…
The Present and Future of QCD
P. Achenbach, D. Adhikari, A. Afanasev +400
This White Paper presents the community inputs and scientific conclusions from the Hot and Cold QCD Town Meeting that took place September 23-25, 2022 at MIT, as part of the Nuclea…
Possible Universal Limit for Valence Parton Distributions
Christopher Leon, Misak M. Sargsian
We report the observation of the existence of a possible universal limit for valence parton distributions that should exist once partonic degrees of freedom are relevant for high e…
Residual Mean Field Model of Valence Quarks in the Nucleon
Christopher Leon, Misak Sargsian
We develop a non-perturbative model for valence parton distribution functions (PDFs) based on the mean field interactions of valence quarks in the nucleonic interior. The main moti…

We present a new approach for the calculation of the valence quark distributions in the nucleon based on the scenario in which the spectrum of the valence quarks at x>0.05 is gener…
Standard convolution description of deuteron tensor spin structure
W. Cosyn, Yu-Bing Dong, S. Kumano +1
Spin-1 hadrons have additional structure functions not present for spin 1/2 hadrons. These could probe novel aspects of hadron structure and QCD dynamics. For the deuteron, the ten…

W. Cosyn, Yu-Bing Dong, S. Kumano +1
There are polarized structure functions for the spin-1 deuteron. We calculated the leading-twist tensor structure function by using convolution description for the…
