Universality class of little string theories
Journal Article

· Physical Review D
We propose that little string theories in six dimensions are quasilocal quantum field theories. Such field theories obey a modification of Wightman axioms which allows Wightman functions (i.e. vacuum expectation values of products of fundamental fields) to grow exponentially in momentum space. Wightman functions of quasilocal fields in x-space violate microlocality at short distances. With additional assumptions about the ultraviolet behavior of quasilocal fields, one can define approximately local observables associated with big enough compact regions. The minimum size of such a region can be interpreted as the minimum distance which observables can probe. We argue that for little string theories this distance is of the order of N/M{sub s}.
