Pure spinor superstring in AdS_4 x CP^3 with unconstrained ghosts
We construct the action for the pure spinor superstring in the coset
description of AdS_4 x CP^3 superspace, using the variables which solve the
pure spinor condition. As a test of the consistency of the approach, we use the
background field method to verify the absence of central charge at the second
order in the expansion and to show the one-loop finiteness of the effective
action.Comment: 23 pages, 2 figure
