I had a look at
N. Berkovits & L. Motl, Cubic Twistorial String Field Theory,
hep-th/0403187
I have to admit that I am (still) not familiar with strings in
twistor space, so let me ask a stupid question:
What about worldsheet supersymmetry? Is there any? If yes, why does the
BRST operator look the way it does in equation (2.4)? If not, why can we
still have a relation to SYM?
Another question: I have a basic understanding of ordinary cubic
bosonic open string field theory. What is, heuristically, the physical
interpretation of the new cubic interaction term in equation (3.19)?
