  NOvA experiment has reoptimized its event selection criteria in light of the
recently measured moderately large value of theta(13). We study the improvement
in the sensitivity to the neutrino mass hierarchy and to leptonic CP violation
due to these new features. For favourable values of deltacp, NOvA sensitivity
to mass hierarchy and leptonic CP violation is increased by 20%. Addition of 5
years of neutrino data from T2K to NOvA more than doubles the range of deltacp
for which the leptonic CP violation can be discovered, compared to stand alone
NOvA. But for unfavourable values of deltacp, the combination of NOvA and T2K
are not enough to provide even a 90% C.L. hint of hierarchy discovery.
Therefore, we further explore the improvement in the hierarchy and CP violation
sensitivities due to the addition of a 10 kt liquid argon detector placed close
to NOvA site. The capabilities of such a detector are equivalent to those of
NOvA in all respects. We find that combined data from 10 kt liquid argon
detector (3 years of nu + 3 years of nubar run), NOvA (6 years of nu + 6 years
of nubar run) and T2K (5 years of nu run) can give a close to 2 sigma hint of
hierarchy discovery for all values of deltacp. With this combined data, we can
achieve CP violation discovery at 95% C.L. for roughly 60% values of deltacp.
