Lorentz violation and generalized uncertainty principle

Understand

Investigations on possible violation of Lorentz invariance have been widely pursued in the last decades, both from theoretical and experimental sides.

• A comprehensive framework to formulate the problem is the standard model extension (SME) proposed by A.Kostelecky, where violation of Lorentz invariance is encoded into specific coefficients.
• Here we present a procedure to link the deformation parameter $\beta$ of the generalized uncertainty principle (GUP) to the SME coefficients of the gravity sector.
• The idea is to compute the Hawking temperature of a black hole in two different ways.
