Resumen:
We perform a perturbative analysis of the Aharonov-Bohm problem to one loop in a field-theoretic formulation and show that contact interactions are necessary for renormalizability. In general, the classical scale invariance of this problem is broken quantum mechanically. There exists, however, a critical point for which this anomaly disappears.
