Color Grosse-Wulkenhaar models: One-loop β-functions
The β-functions of O(N) and U(N) invariant Grosse-Wulkenhaar models are computed at one loop using the matrix basis. In particular, for “parallel interactions”, the model is proved asymptotically free in the UV limit for N > 1, and has a triviality problem or Landau ghost for N < 1. The vanishing β-function is recovered solely at N = 1. We discuss various possible consequences of these results....
متن کاملThe three - loop SSM β - functions
We present the supersymmetric standard model three-loop β-functions for gauge and Yukawa couplings and consider the effect of three-loop corrections on the standard running
متن کاملTwo Loop QCD Vertices and Three Loop MOM β functions
We present numerical results for the two loop QCD corrections to the ghost gluon vertex, the quark gluon vertex, and the triple gluon vertex in the massless limit at the symmetric point. We restrict ourselves to the tensor structures existing in the tree level. The corrections are used to examine different coupling constant definitions in momentum subtraction schemes and the corresponding three...
متن کاملOne-loop β functions of a translation-invariant renormalizable noncommutative scalar model
Recently, a new type of renormalizable φ 4 scalar model on the Moyal space was proved to be perturbatively renormalizable. It is translation-invariant and introduces in the action a a/(θp) term. We calculate here the β and γ functions at one-loop level for this model. The coupling constant βλ function is proved to have the same behavior as the one of the φ 4 model on the commutative R. The βa f...
متن کاملColor antisymmetric ghost propagator and the one loop vertex renormalization
Color matrix elements of the ghost triangle diagram that appears in the triple gluon vertex and the ghost-ghost-gluon triangle diagram that appears in the ghost-gluon-ghost vertex are calculated. The ghost-ghost-gluon triangle contains a loop consisting of two color diagonal ghost and one gluon and a loop consisting of two color antisymmetric ghost and one gluon. Consequently the pQCD argument ...
