In noncommutative SU(N) Yang-Mills theory defined by the theta-exact Seiberg-Witten map, one-loop IR singularities arise from UV/IR mixing, even though there are no ordinary U(1) gauge fields in the theory. This is different from the noncommutative U(N) case, where the two-point part of the effective action involving the ordinary SU(N) fields is not affected by these one-loop IR singularities.
We show that there are one-loop IR singularities arising from UV/IR mixing in noncommutative SU(N) Yang-Mills theory defined by means of the theta-exact Seiberg-Witten map. This is in spite of the fact that there are no ordinary U(1) gauge fields in the theory and this is at variance with the noncommutative U(N) case, where the two-point part of the effective action involving the ordinary SU(N) fields do not suffer from those one-loop IR singularities.
