Abstract
The effects of space-time geometry fluctuations on fermionic fields have recently been looked for in nuclear physics experiments, and were found to be much lower than predicted, at a phenomenological level, by loop quantum gravity. We show that the possible corrections to the canonical structure in the semiclassical regime may introduce important changes in the outcome of the theory, and may explain the observed mismatch with experiments.
