Description
We present the latest results of the MAP collaboration about the extraction of Transverse-Momentum-Dependent (TMD) distributions at the N$^3$LL logarithmic accuracy in the resummation of q$_T$-logarithms. Firstly, we present the most recent extraction of unpolarized quark TMD parton distribution functions (TMD PDFs) in the proton and fragmentation functions (TMD FFs) from a global fit of Drell—Yan and Semi-Inclusive Deep-Inelastic Scattering (SIDIS) data sets. Then, we show our extraction of unpolarized quark TMD PDFs in a pion from a fit of all existing pion-induced Drell--Yan data, showing the necessity of new data to better constrain the TMD curves.
