Descrição: dc.descriptionGeneralized uncertainty principles (GUP) and, independently, Lorentz sym- metry violations are two common features in many candidate theories of quantum gravity. Despite that, the overlap between both has received lim- ited attention so far. In this brief paper, we carry out further investigations on this topic. At the nonrelativistic level and in the realm of commutative spacetime coordinates, a large class of both isotropic and anisotropic GUP models is shown to produce signals experimentally indistinguishable from those predicted by the standard model extension (SME), the common frame- work for studying Lorentz-violating phenomena beyond the standard model. This identification is used to constrain GUP models using current limits on SME coefficients. In particular, bounds on isotropic GUP models are improved by a factor of 107 compared to current spectroscopic bounds and anisotropic models are constrained for the first time.-
