Exact infrared scaling behavior of Randers–Finsler scalar field theories

We study the scaling behavior of Randers–Finsler massless scalar field theories in the infrared regime. For that, we compute analytically the radiative corrections to the corresponding anomalous dimensions, related to the critical exponents of the theory, first up to next-to-leading loop order and later for all-loop levels. We consider the effect of the Randers–Finsler space-time properties on the critical exponents by considering the parameter characterizing those space-times in its exact form. We employ field-theoretic renormalization group and [Formula: see text]-expansion techniques at dimensions [Formula: see text] through three distinct and independent methods. In the end, we furnish the physical interpretation of the obtained results.
