Fractional superstrings with space-time critical dimensions four and six.
We propose possible new string theories based on local world-sheet symmetries corresponding to extensions of the Virasoro algebra by fractional spin currents. They have critical central charges c = 6(K + 8)/(K + 2) and Minkowski space-time dimensions D = 2+16/K for K ≥ 2 an integer. We present evidence for their existence by constructing modular invariant partition functions and the massless pa...
متن کاملFractional Superstrings with Critical Spacetime Dimensions Four and Six : A Status Report
We provide a short non-technical survey of the fundamental issues involved in the recently-proposed fractional superstring theories. After introducing the basic ideas which underlie these new string theories, we review their early successes and outline some related outstanding questions. Talk presented at the International Workshop on String Theory, Quantum Gravity, and the Unification of the F...
متن کاملNon - critical Heterotic superstrings in Various Dimensions
We construct heterotic string theories on spacetimes of the form Rd−1,1×N = 2 linear dilaton, where d = 6, 4, 2, 0. There are two lines of supersymmetric theories descending from the two supersymmetric ten-dimensional heterotic theories. These have gauge groups which are lower rank subgroups of E8×E8 and SO(32). On turning on a (2, 2) deformation which makes the two dimensional part a smooth SL...
متن کاملRadiation Beyond Four Space-Time Dimensions
We present a list of formulas describing classical radiation of the rank s tensor field from an accelerated point-like source in flat space-time of arbitrary even dimension d. This allows straightforward evaluating the total intensity and radiated momentum for any s and d algorithmically, by hands or with the help of a computer (e.g. with an attached MAPLE program). Practical application of for...
متن کاملNon critical superstring configuration and Minkowski space time in four dimensions
We extend the non-perturbative time-dependent bosonic string action of [3] to a N = 1 supersymmetric world sheet action with graviton background, and assume a superpotential, function of the time super coordinate. The use of (super)strings for the description of cosmological events suggests that String Theory might become observable, given the huge amount of cosmological data [1]. String Cosmol...
