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.
