摘要：
A new class of twistor string theories was recently constructed by Abou-Zeid, Hull, and Mason. The most interesting one of these theories has the particle content of N = 8 supergravity. Arguments are given for the vanishing of the ( + - -)-helicity amplitude for gravitons which suggest that this theory describes a chiral N = 8 supergravity rather than Einstein supergravity.
