Query: Adelic Formulas for Gamma and Beta Functions of One-Class Quadratic
  Fields: Applications to 4-Particle Scattering String Amplitudes   Regularized adelic formulas for gamma and beta functions for arbitrary
quasicharacters (either ramified or not) and in an arbitrary field of algebraic
numbers are concretized as applied to one-class quadratic fields (and to the
field of rational numbers). Applications to 4-tachyon tree string amplitudes,
to the Veneziano (open strings) and Virasoro (closed strings) amplitudes as
well as to massless 4-particle amplitudes of the Ramond-Neveu-Schwarz
superstring and a heterotic string are discussed. Certain relations between
different superstring amplitudes are established.
