چکیده
We show that in the supersymmetry framework described by a Poincaré superalgebra with tensorial central charges the role of generalized superconformal symmetry which contains all these central charges is played by OSp(1|2), where k = 3 for D = 4. Following [1,2] we describe the free supertwistor model for OSp(1|8). It appears that in such a scheme the tensorial central charges satisfy additional relations and the model describes the tower of supersymmetric massless states with an arbitrary (integer and half–integer) helicity spectrum.

Classification of N = 4 superconformal symmetries in two dimensions is reexamined. It is proposed that apart from SU(2) and SU(2)×SU(2)×U(1) their Kac-Moody symmetry can also be SU(2) × (U(1)) 4. These supercon-formal symmetries and corresponding algebras are named small, large and middle ones respectively. Operator product expansions for the middle algebra are derived.

Matrix String Theory of Banks, Fischler, Shenker and Susskind can be understood as a generalized quantum theory (provisionally named " quansical " theory) which differs from Adler's generalized trace quantum dynamics. The effective planar Matrix String Theory Hamiltonian is constructed in a particular fermionic realization of Matrix String Theory treated as an example of " quansical " theory.
