Exploring nuclear modification using one-point energy correlator at the electron-ion collider
Yu Fu, Zhong-Bo Kang, Jani Penttala +1
We study the one-point energy correlator (OPEC) at both the back-to-back and collinear limits in electron-proton and electron-nucleus collisions. We provide the factorization forma…
Parton distributions in the shockwave formalism
Shohini Bhattacharya, Chuan-Qi He, Zhong-Bo Kang +2
In this work, we calculate a broad class of parton distributions - including parton distribution functions (PDFs), transverse-momentum-dependent distributions (TMDs), generalized p…
Matching collinear factorization with color-glass condensate for inclusive and exclusive deep inelastic scattering
Shohini Bhattacharya, Chuan-Qi He, Zhong-Bo Kang +2
Collinear factorization and color-glass condensate (CGC) effective field theory are generally treated as separate approaches for calculating scattering amplitudes, valid in differe…
Diffractive deep inelastic scattering in the dipole picture: the contribution in exact kinematics
Abhiram Kaushik, Heikki Mäntysaari, Jani Penttala
We compute the contribution to the diffractive structure functions in high-energy deep inelastic scattering. The obtained result corresponds to a finite part of the nex…
A numerical implementation of the NLO DIS structure functions in the dipole picture
Henri Hänninen, Heikki Mäntysaari, Jani Penttala
We present a numerical program that evaluates deep inelastic scattering (DIS) structure functions at next-to-leading order (NLO) accuracy in the dipole picture. In this numerical i…
Determination of the initial condition for the Balitsky-Kovchegov equation with transformers
Meisen Gao, Zhong-Bo Kang, Jani Penttala +1
In the high-energy limit of QCD, scattering off nucleons and nuclei can be described in terms of Wilson-line correlators whose energy dependence is perturbative. The energy depende…
