Gluon Shadowing Effect in Light and Heavy Nuclei at Small x / A.V.Lipatov, G.I.Lykasov, M.A.Malyshev. – Text : electronic // Physical Review D. – 2025. – Vol. 112, No. 1. – P. 014025. – URL: https://doi.org/10.1103/kr1f-d1bg. – Bibliogr.: 60.
We propose new transverse momentum-dependent (TMD) gluon densities in nuclei. Our method is based on a combination of the color dipole scattering formalism, within which we interpret the nuclear deep inelastic structure functions 𝐹&sup(𝐴)&sub(2)(𝑥,𝑄2) and well-established property of geometrical scaling from nucleons to nuclei. As an input, we employ the TMD gluon density in a proton that provides a self-consistent simultaneous description of the numerous HERA and LHC data on 𝑝𝑝, 𝑒𝑝, and 𝛾𝑝 processes. After fitting the relevant phenomenological parameters to the experimental data on the ratios 𝐹&sup(𝐴)&sub(2)(𝑥,𝑄*2)/𝐹&sup(𝐴′)&sub(2)(𝑥,𝑄*2) for several nuclear targets 𝐴 and 𝐴′, we derive the corresponding nuclear gluon distributions. Then, we make predictions for gluon shadowing effects at small Bjorken 𝑥 in their dependence of the mass number 𝐴. A comparison with other approaches is given.
