Infrared-regulated string theory and loop corrections to coupling constants
Exact superstring solutions are constructed in 4-D space-time, with positive curvature and non-trivial dilaton and antisymmetric tensor fields. The full spectrum of string excitations is derived as a function of moduli fields T^{i} and the scale \mu^2=1/(k+2) which is induced by the non-zero backgro...
