Description
The tensor charge, namely the first Mellin moment of the chiral-odd transversity parton distribution, is not connected to operators entering the Standard Model Lagrangian at tree level. It could represent a low-energy footprint of new physics happening at much higher scales, hence it is important to know it with very high precision. I will present the latest results obtained by extracting the transversity distribution from a global analysis of pion-pair production in deep-inelastic scattering and in proton-proton collisions. In particular, I will discuss the impact of pseudodata connected to future more precise measurements at both medium-low and high parton fractional momenta, and I will compare the projected results with recent lattice calculations of the valence and isovector components of the tensor charge.
