Title: Study of evolution of Transverse Momentum Dependent distributions.

Abstract: Transverse Momentum Dependent distribution and fragmentation  functions (TMDs) reveal spin partonic structure of hadrons. They also allow us to obtain so-called three dimensional partonic picture. 
Different experiments such as HERMES and COMPASS measure spin asymmetries related to TMDs at different energies and different hard scales Q^2. 
Evolution of TMDs was derived in recent book by John Collins and papers by Mert Aybat and Ted Rogers.In the talk I am going to explain how TMDs evolve with energy and hard scale and present comparison with recent experimental data from COMPASS. I will also present predictions of Drell-Yan asymmetries with evolution of TMDs for future measurements of COMPASS.
