  The effects of collisional processes in the hot QCD medium to thermal
dilepton production from $q\overline{q}$ annihilation in relativistic heavy-ion
collisions have been investigated. The non-equilibrium corrections to the
momentum distribution function have been estimated within the framework of
ensemble-averaged diffusive Vlasov-Boltzmann equation, encoding the effects of
collisional processes and turbulent chromo-fields in the medium. The
contributions from the $2\rightarrow2$ elastic scattering processes have been
quantified for the thermal dilepton production rate. It is seen that the
collisional corrections enhance the equilibrium dilepton spectra at high $p_T$
and suppress at lower $p_T$. A comparative study between collisional and
anomalous contributions to the dilepton production rates has also been
explored. The collisional contributions are seen to be marginal over that due
to collisionless anomalous transport.
