SUMMARY
The Standard Model (SM) cannot generate neutrino masses through loop-level interactions due to the absence of right-handed neutrinos and explicit lepton number violation. While the SM does exhibit non-perturbative lepton number violation, it is accompanied by baryon number violation, which conserves B-L. Consequently, the generation of Dirac or Majorana masses for neutrinos is not feasible within the framework of the SM.
