Infrared Consistency of NSVZ and DRED Supersymmetric Gluodynamics
نویسنده
چکیده
Padé approximant methods are applied to the known terms of the DRED β-function for N = 1 supersymmetric SU(3) Yang-Mills theory. Each of the [N |M ] approximants with N + M ≤ 4, M 6= 0 constructed from this series exhibits a positive pole which precedes any zeros of the approximant, consistent with the same infrared-attractor pole behaviour known to characterize the exact NSVZ β-function. A similar Padé-approximant analysis of truncations of the NSVZ series is shown consistently to reproduce the geometric-series pole of the exact NSVZ β-function.

Scheme dependence and the NSVZ β - function
We investigate the connection between the NSVZ and the DRED forms of the gauge β-function in an N = 1 supersymmetric gauge theory. We construct a coupling constant redefinition that relates the two forms up to four loops. By abelian calculations, we are able to infer the complete non-abelian form of β

We calculate the three loop gauge β-function for an abelian N = 1 supersymmetric gauge theory, using DRED. We construct a coupling constant redefinition that relates the result to the corresponding term in the NSVZ β-function, and by generalising this redefinition to the non-abelian case we derive the DRED three loop gauge β-function for the non-abelian case.

متن کاملTwo phases of supersymmetric gluodynamics.
We argue that supersymmetric gluodynamics has two phases with equivalent infrared behavior, one of which is asymptotically free and another one is superstrongly coupled in the ultraviolet domain. Supersymmetric (SUSY) gauge theories are unique examples of non-trivial fourdimensional theories where some dynamical aspects are exactly tractable. The first results of this type – calculation of the ...

Padé-approximant treatments of the known terms of the QCD β-function are seen to develop possible infrared fixed point structure only if the number of fermion flavours is sufficiently large. This flavour threshold is seen to be between six and nine flavours, depending upon both the specific choice of approximant as well as on the presently-unknown five-loop β-function contribution. Below this f...
