Abstract:
We argue for the existence of phase transitions in dimensions associated with the appearance of tensionless strings. The massless spectrum of this theory does not contain a graviton: it consists of one vector multiplet and one linear multiplet, in agreement with the light-cone analysis of the Green-Schwarz string in dimensions. In M-theory the string decoupled from gravity arises when two 5-branes intersect over a three-dimensional hyperplane. The two 5-branes may be connected by a 2-brane, whose boundary becomes a tensionless string with supersymmetry in dimensions. The near-extremal entropy of the intersecting 5-branes is in agreement with that of a string at its Hagedorn temperature.Note:
