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...

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...

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...

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 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,...

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...

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...

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...

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...

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...
