    Extraction of the Sivers function from SIDIS, Drell-Yan, and boson production data with TMD evolution

    Marcin Bury🇩🇪 · Alexei Prokudin🇺🇸 · Alexey Vladimirov🇩🇪

    We perform a global fit of the available polarized Semi-Inclusive Deep Inelastic Scattering (SIDIS), polarized pion-induced Drell-Yan (DY) and boson production data at NLO and NNLO accuracy of the Transverse Momentum Dependent (TMD) evolution, and extract the Sivers function for , , and for sea quarks. The Qiu-Sterman function is determined in a model independent way via the operator product expansion from the extracted Sivers function. The analysis is supplemented by additional studies, such as the estimation of applicability region, the impact of the unpolarized distributions' uncertainties, the universality of the Sivers functions, positivity constraints, the significance of the sign-change relation, and the comparison with the existing extractions

    Nuclear binding energy in holographic QCD

    Koji Hashimoto🇯🇵 · Yoshinori Matsuo🇯🇵

    Saturation of the nuclear binding energy is one of the most important properties of atomic nuclei. We derive the saturation in holographic QCD, by building a shell-model-like mean-field nuclear potential from the nuclear density profile obtained in a holographic multi-baryon effective theory. The numerically estimated binding energy is close to the experimental value.
