One-Loop Calculation of Coupling Constants in IR regulated String Theory

  title={One-Loop Calculation of Coupling Constants in IR regulated String Theory},
  author={Elias Kiritsis and Costas Kounnas},
Exact Superstring solutions are constructed moving 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 µ 2 = 1/(k + 2) which induced by the non-zero background fields. The spectrum of string excitations has a non-zero mass gap µ 2 and in the weak curvature limit (µ small) µ 2 plays the role of a well defined infrared regulator, consistent with… CONTINUE READING
