| contents | In this paper, we derive the renormalization scale dependence of noncommutative mirror Yukawa couplings. To achieve this, we first formulate an Euclidean noncommutative version of the Yukawa sector within the electroweak-scale mirror right handed neutrinos model. Then, we calculate the noncommutative one loop $β$ functions of Yukawa couplings for mirror fermions involved in this model, by taking advantage of the Slavnov Taylor identities for the universal mirror Yukawa couplings, and by using the noncommutative vulcanised scalar and spinor propagators that prevent the UV/IR mixing. This leads us to a system of six cubic coupled first order differential equations that depend only on the mirror Yukawa couplings and not on the noncommutative deformation and vulcanised parameters. We solve this system numerically for different initial conditions to get the evolution of the mirror Yukawa couplings in terms of the renormalization scale. Furthermore, we discuss the link to the commutative case and analyze the occurrence of the Landau pole for some specific sets of initial conditions. |
