Generalized Parton Distributions and Distribution of Partons in the Transverse Plane [PDF]
, 2001 I discuss the physical interpretation of GPDs in the limit $\xi=0$, where the $t$ dependence contains information about the distribution of partons in the transverse plane.

Unintegrated parton distributions [PDF]
Physical Review D, 2001 We describe how to calculate the parton distributions $f_a(x, k_t^2, ^2)$, unintegrated over the parton transverse momentum $k_t$, from auxiliary functions $h_a(x, k_t^2)$, which satisfy single-scale evolution equations. The formalism embodies both DGLAP and BFKL contributions, and accounts for the angular ordering which comes from coherence effects ...

Improved background subtraction and a fresh look at jet sub-structure in JEWEL
European Physical Journal C: Particles and Fields, 2022 Interactions of hard partons in the Quark Gluon Plasma (QGP) created with relativistic heavy ion collisions lead to characteristic modifications of the internal structure of reconstructed jets. A large part of the observed jet sub-structure modifications

The double-soft integral for an arbitrary angle between hard radiators
European Physical Journal C: Particles and Fields, 2018 We consider the double-soft limit of a generic QCD process involving massless partons and integrate analytically the double-soft eikonal functions over the phase-space of soft partons (gluons or quarks) allowing for an arbitrary relative angle between ...

Anomalously light mesons in a (1+1)-dimensional supersymmetric theory with fundamental matter [PDF]
, 2003 We consider N=1 supersymmetric Yang-Mills theory with fundamental matter in the large-N_c approximation in 1+1 dimensions. We add a Chern-Simons term to give the adjoint partons a mass and solve for the meson bound states.

Soft radiation in parton-parton scattering
Nuclear Physics B, 1987 Abstract We investigate the pattern of soft gluon radiation associated with parton-parton scattering by explicit evaluation of the 2 → 3 scattering processes in the soft limit. After azimuthal averaging, the results provide the initial conditions for an angular-ordering approximation to coherent multiple soft gluon emission, which may be incorporated

Parton coalescence at RHIC [PDF]
, 2003 Using a covariant coalescence model, we study hadron production in relativistic heavy ion collisions from both soft partons in the quark-gluon plasma and hard partons in minijets. Including transverse flow of soft partons and independent fragmentation of

Antenna subtraction for jet production observables in full colour at NNLO
Journal of High Energy Physics, 2022 We describe the details of the calculation of the full colour NNLO QCD corrections to jet production observables at the LHC with antenna subtraction. All relevant matrix elements for the process pp → jj at NNLO in full colour are colour-decomposed and ...

Recombination of Shower Partons at High $p_T$ in Heavy-Ion Collisions
, 2004 A formalism for hadron production at high \pt in heavy-ion collisions has been developed such that all partons hadronize by recombination. The fragmentation of a hard parton is accounted for by the recombination of shower partons that it creates.
