  The effects of radiation reaction force on laser driven auto-resonant
particle acceleration scheme are studied using Landau-Lifshitz equation of
motion. These studies are carried out for both linear as well as circularly
polarized laser fields in the presence of static axial magnetic field. From the
parametric study, a radiation reaction dominated region has been identified in
which the particle dynamics is greatly effected by this force. In the radiation
reaction dominated region the two significant effects on particle dynamics are
seen viz., (1) saturation in energy gain by the initially resonant particle,
(2) net energy gain by a initially non-resonant particle which is caused due to
resonance broadening. It has been further shown that with the optimum choice of
parameters this scheme can be efficiently used to produce electrons with
energies in the range of hundreds of TeV. The quantum corrections to the
Landu-Lifshitz equation of motion have also been taken into account. The
difference in the energy gain estimates of the particle by the quantum
corrected and classical Landu-Lifshitz equation are found to be insignificant
for the present day as well as upcoming laser facilities.
