I will present a brief summary of previous studies estimating the size of theoretical uncertainties for the determination of the W mass, and I will show recent updates including flavour-dependent TMD effects.

Twist-3 Generalized Parton Distributions (GPDs) may provide an alternative source of information on quark orbital angular momentum. Additionally, twist-3 GPDs embody information on the spatial distribution of quark-gluon correlations. Spectator models are used to study general features that appear in twist-3 GPDs. We find in 1 loop calculations/spectator models that twist-3 generalized parton dist ... More

In this talk, we discuss the transverse momentum distribution of Drell-Yan lepton pairs in fixed-target Drell-Yan experiments. We show that fixed-order theory underestimates data at large qT, by an amount that cannot be explained by perturbative truncation errors nor PDF uncertainties. We consider a modification of the standard collinear formalism that includes the effect of intrinsic transverse ... More

We present the first extraction of the transversity distribution based on the global analysis of pion-pair production in deep-inelastic scattering and in proton-proton collisions with one transversely polarized proton. The extraction relies on the knowledge of di-hadron fragmentation functions, which are taken from the analysis of electron-positron annihilation data. For the first time, the chiral ... More

Gluon fusion is the primary source of top-antitop pair production at the LHC. The spin dependences of proton gluon distributions impact the spin correlations of the top pairs. Decays of top pairs through different channels produce a variety of correlations among the decay products - single particles and jets. Combinations of the gluon distributions, either polarized or unpolarized, can be accessed ... More

We present a first computation of the differential cross-section for in- clusive prompt-photon production in DIS to next-to-leading order (NLO) in αS at small-x within the framework of the Color Class condensate (CGC) [1]. The computation is performed to next-to-leading-log x (NLLx) accuracy and resums all higher twist contributions within the CGC effec- tive theory. Our work is within the same f ... More

The mass of heavy quarks, such as charm and bottom, plays an important role in the formation of parton showers. This effect is apparently not well understood when parton showers evolve in a strongly interacting quark-gluon plasma. We propose a new experimental measurement in relativistic heavy ion collisions, based on a two-prong subjet structure inside a reconstructed heavy flavor jet, which ... More

In this talk, I will develop the theoretical framework of jet substructure measurements in the semi-inclusive jet production. The talk will mainly be focused on the recent work on jet mass measurements, with and without grooming, as a particular substructure of interest. I will discuss factorization, nonperturbative effects, and joint resummations of several classes of logarithmic corrections to a ... More

We present a lattice-QCD calculation of the unpolarized isovector parton distribution func- tion (PDF) using ensembles at the physical pion mass with the large proton boost momentum Pz ? {2.2, 3.0} GeV within the framework of large-momentum effective theory (LaMET). In contrast with our previous physical-pion PDF result, we increase the statistics significantly, double the boost momentum, increase ... More

High precision data of dilepton angular distributions in ??/Z production were reported recently by the CMS and ATLAS Collaboration covering a broad range of the dilepton transverse momentum, qT, up to ?300GeV. Pronounced qT dependencies of the ? and ? parameters, characterizing the cos2? and cos2? angular distributions, were found. Violation of the Lam?Tung relation was also clearly observed. We s ... More

The formulation of transverse momentum dependent distributions derived from the factorization of differential cross section allows a systematical analysis of polarized distributions. We consider in particular the case of twist-3 distributions and explore the properties in the matching with their collinear integrated parton distributions.

A typical factorization formula for production of a particle with a small transverse momentum in hadron-hadron collisions is given by a convolution of two TMD parton densities with cross section of production of the final particle by the two partons. For practical applications at a given transverse momentum, though, one should estimate at what momenta the power corrections to the TMD factoriz ... More

The Direct calculation of x-dependent parton distribution functions (PDFs) are not possible using ab initio Euclidean-space Lattice QCD, due to their definitions in terms of light-cone coordinates. I present the recent Lattice QCD calculation of pseudo PDFs, a Lorentz invariant generalization of light cone PDFs. These Lorentz invariant functions can be calculated on a Euclidean lattice and related ... More

We consider the transverse momentum spectrum of quarkonium produced in hadronic collisions. For traverse momentum parametrically smaller compared to its mass, in the central rapidity region, the quarkonium is produced nearly at rest and other particles in the event can only be soft and/or collinear along the beam direction. We use non-relativistic QCD (NRQCD) to describe the dynamics of the heav ... More

The factorization theorem for DY and semi-inclusive DIS holds for all leading twist transverse momentum distributions. However a QCD perturbative calculation shows several important characteristics of spin-dependent distributions. We consider all the different spin-dependent distributions which can be matched onto integrated twist-2 functions, focusing on the Helicity, Transversity and Pretzelo ... More
