The structure of a pseudo-scalar fermion-antifermion bound state is i nvestigated through the solution of the Bethe-Salpeter equation in Minkowski space. The kernel is truncated to the ladder approximation, a form factor is introduced in the vertex, with the exchanged particle being a massive, scalar, pseudo-scalar or a vector boson. The method used for the numerical solution of the...

Due to their self-analyzing decay, the polarization of Λ hyperons has often been indicated as a possible way to access the transversity function h_1^{q}(x) in SIDIS, where it comes coupled to the chiral-odd H_1^{Λ/q}(z) fragmentation function. Such Λ transversity-transmitted polarization has been measured in COMPASS using the data collected with a transversely polarized proton target and a 160...

We present an updated phenomenological analysis on transverse Single-Spin Asymmetries (SSAs) for inclusive hadron production in lepton-proton scattering. Adopting a transverse momentum dependent approach, we focus on the role of quasi-real (Weizsacker-Williams) photon exchange, showing its relative contribution to SSAs. Then, using the Sivers and the transversity distributions and the Collins...

The production of heavy flavor quark pairs, especially top-anti-top at the LHC, proceed primarily through gluon fusion. Correlations between the gluon spins affects spin correlations between the produced quark and anti-quark. For top-antitop production, their spin asymmetries and double correlations of spins will be manifest in the subsequent hadronization and decay distributions. These...

We discuss the impact of the determination of the nucleon tensor charge on searches for physics Beyond the Standard Model. We also comment on the future extraction of the subleading-twist PDF e(x) from Jefferson Lab soon-to-be-released Beam Spin Asymmetry data as well as from the expected data of CLAS12, as the latter is related to the scalar charge. These analyses are possible through the...
