Pion parton distribution functions and pion-nucleus induced $J/\psi$ production in extended light-front holographic QCD

Chandan Mondal, Jiangshan Lan, Satvir Kaur

Pion PDFs from combined holographic and 't Hooft light-front wave functions, used with nuclear PDFs, produce NLO cross sections for J/ψ production in pion-nucleus collisions that match experimental data.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

These pion PDFs, together with nuclear PDFs, are then used to compute the differential cross sections up to next-to-leading order for inclusive J/ψ production in pion-nucleus collisions, which show good agreement with experimental data across different energies and nuclear targets.

C2weakest assumption

The light-front wave functions obtained from the holographic Schrödinger equation of light-front chiral QCD combined with the 't Hooft equation in (1+1)-dimensional QCD at large Nc accurately determine the pion PDFs.

C3one line summary

Pion PDFs from holographic light-front QCD are consistent with global analyses and produce J/ψ cross sections matching experimental data across energies and targets.
