6. New Perspectives on Precision Nucleon Tomography

This talk presents new perspectives on precision nucleon tomography using high-order QCD calculations and jet substructure. I will discuss the winner-take-all axis for extending qT subtraction to jet processes, enabling NNNLO predictions for SIDIS. Novel observables such as one-point energy correlators access the nucleon transversity distribution. Furthermore, we explore quantum decoherence in...

42. NNLL fit of the unpolarised gluon TMD PDF

Transverse-momentum-dependent (TMD) parton distribution functions encode the three-dimensional structure of the proton, but the gluon sector remains far less constrained than the quark one. Double $J/\psi$ production at the LHCb is a particularly clean probe of gluon TMDs: at LHCb kinematics it is dominated by gluon-gluon fusion, and in the region of small pair transverse momentum it is...

27. TMD Evolution and Large-(b_T) Effects in Low-(q_T) Drell–Yan Production at the LHC

Mohammad Danyal Zarei (Faculty of Physics, University of Arak)

We study the impact of transverse-momentum-dependent (TMD) evolution on the low-(q_T) spectrum of Drell–Yan lepton-pair production at the Large Hadron Collider. We consider the process (pp \to Z/\gamma^* \to \mu^+\mu^- + X) at (\sqrt{s}=13.6) TeV in the (Z)-boson mass region, focusing on the kinematic regime (q_T \ll M_Z), where TMD factorization is applicable.The (q_T) distribution is...
