Dear Deep Processes,

I would like to submit an abstract for the 10th workshop of APS GHP
in Minneapolis, Minnesota, with the deadline on Feb 1st.
Best regards,

The title "Experimental Studies of Evolution Properties of Structure
Functions in Polarized SIDIS"

The quark-gluon dynamics manifests itself in a set of non-perturbative
functions  describing all possible  spin-spin and spin-orbit correlations.
Single and Dihadron semi-inclusive and hard exclusive production, both in
current  and target fragmentation regions, provide a variety of spin and
azimuthal angle dependent observables, sensitive to the dynamics of
quark-gluon interactions. Studies of spin-dependent structure functions,
and underlying transverse momentum distributions of partons are currently
driving the upgrades of several existing facilities, and the design and
construction of new facilities worldwide.
In this talk, we present some ongoing and possible future studies of
Q^2-dependences of structure functions in SIDIS, required for validation of
existing theoretical description of SIDIS.
