Universality hypothesis breakdown at one-loop order
P. R. S. Carvalho
We probe the universality hypothesis by analytically computing, at least, the two-loop corrections to the critical exponents for -deformed O() self-interacting scala…

Exact Lorentz-violating all-loop ultraviolet divergences in scalar field theories
P. R. S. Carvalho, M. I. Sena-Junior
In this work we evaluate analytically the ultraviolet divergences of Lorentz-violating massive O() scalar field theories, which are exact in the Lorentz-violating mecha…

Critical properties of scalar field theory with Lorentz violation: Exact treatment of Lorentz-violating mechanism
P. R. S. Carvalho, M. I. Sena-Junior
In this work, we compute analytically the infrared divergences of massless O() self-interacting scalar field theories with Lorentz violation, which are exact in the Lorentz-viol…
