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.
