  1. 76. The gT(x) contribution to single spin asymmetry in SIDIS
    Sanjin Benic
    10/19/21, 8:30 PM
    Transverse momentum structure (TMD)
    Parallel Session Presentation

    I will talk about our recent computation [1] of a gT(x) contribution to transverse single spin asymmetry (SSA) in SIDIS in a collinear framework. In [1] we have found that gT(x) first appears at two-loops. I will explain main steps of our calculation and show the final formula for the cross section [2] in the Wilczek-Wandzura (WW) approximation, that is, neglecting the genuine twist-3 pieces....

  2. 163. TMDs and EIC impact studies
    Matteo Cerutti (University of Pavia and INFN)
    10/19/21, 9:00 PM
    Future facilities and experiments
    Parallel Session Presentation

    Semi-Inclusive Deep-Inelastic Scattering (SIDIS) is one of the processes that allow us to extract information about Transverse Momentum Distributions (TMDs) and will be the main channel to access TMDs at the future Electron Ion Collider (EIC).
    We provide an estimate of the impact that EIC data will have on unpolarized Transverse-Momentum Dependent (TMD) Parton Distribution Functions (PDFs)...

  3. 114. Nucleon isovector tensor charge from lattice QCD with physical light quark masses
    Ryutaro Tsuji (Tohoku University)
    10/19/21, 9:20 PM
    Transverse momentum structure (TMD)
    Parallel Session Presentation

    We will present the current status of nucleon structure studies with physical light quarks ($m_\pi$ = 135 MeV) in two large spatial extents of about 10 and 5 fm. Our calculations are performed on 2+1 flavor gauge configurations generated by PACS collaboration with the stout-smeared $O(a)$ improved Wilson fermions and Iwasaki gauge action at $\beta$=1.82 corresponding to the lattice spacing of...

  4. 32. TMD cross-section factorization for dijet production at the EIC
    Rafael F. del Castillo (Universidad Complutense de Madrid)
    10/19/21, 9:40 PM
    Transverse momentum structure (TMD)
    Parallel Session Presentation

    We use soft collinear effective theory (SCET) to study a dijet production process in deep-inelastic-scattering (DIS), measuring the imbalance of the two hard probes in the Breit frame. In order to achieve factorization of the transverse momentum dependent (TMD) cross-section, we need to introduce a new soft function that we calculate at one-loop, regulating rapidity divergencies with the...

  5. 1. Exclusive Double Drell-Yan factorization and GTMDs
    Transverse momentum structure (TMD)
    Parallel Session Presentation

    In this talk we show how to apply the Soft-Collinear Effective Theory formalism to factorize the Exclusive Double Drell-Yan process, which gives access to Generalized TMDs as well as double TMDs. We discuss the relevance of the soft factor in the factorization theorem and its role in the definition of the GTMDs.
