  We have studied the effect of the Dzyaloshinskii-Moriya interaction on kagome
Heisenberg anti-ferromagnet using Schwinger boson mean field theory (SBMFT).
Within SBMFT framework, Messio et al had argued that the ground state of kagome
antiferromagnet is possibly a chiral topological spin liquid (Phys. Rev. Lett.
108, 207204 (2012)). Thus, we have computed zero-temperature ground state phase
diagram considering the time-reversal breaking states as well as fully
symmetric Ans\"atze. We discuss the relevance of these results in experiments
and other studies. Finally, we have computed the static and dynamic spin
structure factors in relevant phases.
