Generalized uncertainty principle and Asymptotic Safe gravity
Abstract
We present a procedure to link the deformation parameter of the generalized uncertainty principle (GUP) to the two free parameters and of the running Newtonian coupling constant of the Asymptotic Safe gravity (ASG) program. To this aim, we compute the Hawking temperature of a black hole in two different ways. The first way involves the use of the GUP in place of the Heisenberg uncertainty relations, and therefore we get a deformed Hawking temperature containing the parameter . The second way involves the deformation of the Schwarzschild metric due to the Newtonian coupling constant running according to the AS gravity prescription. The comparison of the two techniques yields a relation between and , . As a particular case, we discuss also the so called -model. The relations between and , allow us to transfer upper bounds from one parameter to the others.
