 Abstract:

 Transverse-spin and transverse-momentum effects in the nucleon are
 observed in a variety of processes (SIDIS, Drell-Yan, hadron production
 in p-p and e-p reactions etc.). Among these the electro-production
 reaction provide one of the cleanest ways to probe the transverse
 polarization effects in the nucleon, by measuring the single (SSA) and
 double spin (DSA) azimuthal asymmetries in the semi-inclusive deep
 inelastic scattering. These asymmetries provide  an access to different
 types of novel transverse momentum dependent (TMD) parton distribution
 functions, and help in understanding the underlying phenomenon at
 partonic level using different theoretical formalisms. I will talk about
 some of these effects with a focus on recent results from Hall-A
 transversity experiment, and also discuss some high precision
 measurements planned for the future in Hall-A.
