英文摘要: In the effective field theory of quantum gravitation coupled to N-s scalars, N-f fermions, and N-V vectors, tree unitarity is violated at an energy squared of E-CM(2) = 20(G(N)N)(-1), where N &3bond; 2/3N(s) + N-f +4N(V) and G(N) is Newton's constant. This is 3 related to radiative corrections proportional to G(N)NE(2) (where E is the typical energy), due to loops of such particles. New physics must enter before E-CM approximate to 6 x 10(18) GeV in the standard model, and 4 x 10 18 GeV in the minimal supersymmetric standard model. (c) 2005 Elsevier B.V. All rights reserved.
