Twistor String Theory

A chiral superfield strength in [Formula: see text] conformal supergravity at linearized level is obtained by acting two superspace derivatives on [Formula: see text] chiral superfield strength which can be described in terms of [Formula: see text] twistor superfields. By decomposing SU (4)R representation of [Formula: see text] twistor superfields into the SU (2)R representation with an invariant U (1)R charge, the surviving [Formula: see text] twistor superfields contain the physical states of [Formula: see text] conformal supergravity. These [Formula: see text] twistor superfields are functions of homogeneous coordinates of weighted complex projective space WCP3|4 where the two weighted fermionic coordinates have weight -1 and 3.
