1. Probing the two-scale-factor universality hypothesis by exact rotation symmetry-breaking mechanism / Neto, J. F. S. ; Lima, K. A. L. ; Carvalho, P. R. S. ; Sena-Junior, M. I.
We probe the two-scale-factor universality hypothesis by evaluating, firstly explicitly and analytically at the one-loop order, the loop quantum corrections to the amplitude ratios for O ( N ) λϕ4 scalar field theories with rotation symmetry breaking in three distinct and independent methods in which the rotation symmetry-breaking mechanism is treated exactly.

2. Exact Lorentz-violating all-loop ultraviolet divergences in scalar field theories / Carvalho, P. R. S. ; Sena-Junior, M. I.
In this work we evaluate analytically the ultraviolet divergences of Lorentz-violating massive O( N ) λϕ4 scalar field theories, which are exact in the Lorentz-violating mechanism, firstly explicitly at next-to-leading order and latter at any loop level through an induction procedure based on a theorem following from the exact approach, for computing the corresponding critical exponents.
