摘要
The twistor superstring, which describes N=4 super Yang-Mills trees, is taken off-shell (for loops) by generalizing Penrose twistors (which describe on-shell momenta) to Atiyah-Drinfel'd-Hitchin-Manin twistors (which include the usual spacetime coordinates). The resulting string is then shown to be the tensionless limit of a Quantum ChromoDynamics-like superstring.
