• A new two-loop radiative Majorana neutrino mass model is constructed from the gauge-invariant effective operator L super(i) L super(j) Q super(k) d super(c) Q super(l) d super(c) sub( ik) sub(jl) that violates lepton number conservation by two units. The ultraviolet completion features two scalar leptoquark flavors and a color-octet Majorana fermion. We show that there exists a region of parameter space where the neutrino oscillation data can be fitted while simultaneously meeting flavor-violation and collider bounds. The model is testable through lepton flavor-violating processes such as mu arrow right e gamma , mu arrow right eee, and mu N arrow right eN conversion, as well as collider searches for the scalar leptoquarks and color-octet fermion. We computed and compiled a list of necessary Passarino-Veltman integrals up to boxes in the approximation of vanishing external momenta and made them available as a Mathematica package, denoted as ANT.
