70. Unpolarized Structure function in SIDIS: from small to large transverse momentum

A unified description of the transverse-momentum spectrum in semi-inclusive deep-inelastic scattering (SIDIS) requires consistent matching between the low-$P_{hT}$ TMD regime and the high-$P_{hT}$ collinear regime. While this is well established at leading power for unpolarized structure functions, discrepancies arise at subleading power, where contributions may be phenomenologically...

38. Fragmentation contributions to transverse nucleon spin observables in semi-inclusive deep-inelastic scattering at NLO

We study the spin-dependent cross section in semi-inclusive deep-inelastic lepton-nucleon collisions. We focus on the cross section that is integrated over the transverse momentum of the detected unpolarized hadron. We analyze this cross section at large virtuality of the exchanged virtual photon within the framework of collinear twist-3 factorization in perturbative QCD. The two main...

103. Flavor-Dependent Nuclear PDFs from A$\leq$3 SIDIS

A model independent decomposition of nuclear parton distribution functions for $A$$=$3 mirror nuclei into flavor-averaged ($\varepsilon_{\mathrm{avg}}$) and flavor-asymmetric ($\varepsilon_{\mathrm{a}}$) response functions is presented, where $\varepsilon_{\mathrm{a}} \neq 0$ is the condition for a flavor-dependent EMC effect. The full nPDFs for triton and helion are constructed from bound...

73. Double parton scattering off nuclei and double EMC effect

In recent years, significant efforts have been devoted to characterize signatures of Double Parton Scattering (DPS) in hadronic collisions, the simplest process within the set of multiple parton scatterings. Notably, it has been found that DPS plays a crucial role in the studies of Standard Model processes and beyond, when high accuracy is required. The DPS cross-section depends on new...
