INFINITE-DIMENSIONAL SYMMETRIES OF THE TWISTOR STRING MODELS

Uvarov D. V.

Information About Author:

It is shown that similarly to massless superparticle models, space-time symmetry of the classical action of the Berkovits twistor string is infinite-dimensional. Its superalgebra contains finite-dimensional subalgebra that includes the generators of psl(4|4, R) superalgebra. In quantum theory this infinite-dimensional symmetry breaks down to SL(4|4, R) one.

Keywords: supertwistor, twistor string, infinite-dimensional symmetry, anomaly
