Abstract

We examine the influence of exact Lorentz-violating symmetry mechanism on the radiative quantum corrections to the critical exponents for massless qq-deformed O(NN) λϕ4\lambda\phi^{4} scalar field theories. For that, we employ three different and independent field-theoretic renormalization group methods for computing analytically the qq-deformed critical exponents up to next-to-leading order. Then we generalize the former finite loop level results for any loop order. We show that the Lorentz-violating qq-deformed critical exponents, obtained through the three methods, turn out to be identical and furthermore the same as their Lorentz-invariant qq-deformed ones. We argue that this result is in accordance with the universality hypothesis.
