“…In Fig. 6, we plot the transverse polarization as a function of z Λ at Q = 10 GeV and x B = 0.1, which are consistent with the typical kinematics at the future Electron Ion Collider (EIC) [46][47][48][49]. We have used the CT14lo collinear PDFs given in [50].…”

We demonstrate that spontaneous transverse polarization of Lambda baryon (Λ) production in e + e − annihilation can be described using the transverse momentum dependent polarizing fragmentation functions (TMD PFFs). Using a simple Gaussian model, we perform an extraction of the TMD PFFs by fitting the BELLE collaboration's recent measurement of the Λ transverse polarization in back-to-back Λ + h production in e + e − collisions, e − + e + → Λ ↑ + h + X. We find that this simple model accurately describes the experimental data for Λ production associated with pions and kaons, and we are able to determine TMD PFFs for different quark flavors. We use these newly extracted TMD PFFs to make predictions for the transverse polarization of Λ produced in semiinclusive deep inelastic scattering at a future electron-ion collider, and find that such a polarization is around 10% and should be measurable.

“…The latter are related to the number density of two partons located at a given transverse separation in coordinate space with given longitudinal momentum fractions. The information encoded in these distributions therefore complements that accessed through electromagnetic probes in terms of generalized parton distributions (GPDs) [5,6], one of the flagships of the future Electron Ion Collider (EIC) [7]. If measured, dPDFs would therefore represent a novel tool to study the threedimensional hadron structure [8][9][10][11][12].…”

We present an analysis of two-current correlations for the pion in the Nambu-Jona-Lasinio model, with Pauli-Villars regularization. We provide explicit expressions in momentum space for two-current correlations corresponding to the zeroth component of the vector Dirac bilinear in the quark vertices, which has been evaluated on the lattice. The numerical results show a remarkable qualitative agreement with recent lattice data. The factorization approximation into one-body currents is discussed.

Motivated by the desire to understand the nucleon mass structure in terms of light-cone distributions, we introduce the twist-four parton distribution function F (x) whose first moment is the gluon condensate in the nucleon. We present the equation of motion relations for F (x) and discuss the possible existence of the delta function ('zero mode') contribution at x = 0. We also perform one-loop calculations for quark and gluon targets.
