Abstract The transverse momentum-dependent fragmentation functions (TMD FFs) of heavy (bottom and charm) quarks, which we recently introduced, are universal building blocks that enter predictions for a large number of observables involving final-stat

Abstract The heavy jet mass event shape has large perturbative logarithms near the leading order kinematic threshold at ρ = 1 3 $$ \rho =\frac{1}{3} $$ . Catani and Webber named these logarithms Sudakov shoulders and resummed them at double-logarith

Abstract We initiate the study of transverse momentum-dependent (TMD) fragmentation functions for heavy quarks, demonstrate their factorization in terms of novel nonperturbative matrix elements in heavy-quark effective theory (HQET), and prove new TM

Abstract The extraction of nonperturbative TMD physics is made challenging by prescriptions that shield the Landau pole, which entangle long- and short-distance contributions in momentum space. The use of different prescriptions then makes the compar

Abstract We consider Drell-Yan production pp → V * X → LX at small q T ≪ Q, where q T and Q are the total transverse momentum and invariant mass of the leptonic final state L. Experimental measurements require fiducial cuts on L, which in gener

Abstract Jet vetoes are widely used in experimental analyses at the LHC to distinguish different hard-interaction processes. Experimental jet selections require a cut on the (pseudo)rapidity of reconstructed jets, |η jet| ≤ η cut. We extend the s

Abstract We consider Drell-Yan production pp → Z/γ ∗ → ℓ + ℓ − with the simultaneous measurement of the Z-boson transverse momentum q T and 0-jettiness T 0 $$ {\mathcal{T}}_0 $$ . Since both observables resolve the initial-state QCD radi

Abstract Gluon-induced processes such as Higgs production typically exhibit large perturbative corrections. These partially arise from large virtual corrections to the gluon form factor, which at timelike momentum transfer contains Sudakov logarithms

We propose an observable q* sensitive to transverse momentum dependence (TMD) in eN→ehX, with q*/EN defined purely by lab-frame angles. In 3D measurements of confinement and hadronization this resolves the crippling issue of accurately reconstructi
