SUMMARY:Quantum gravity as an EFT\, black hole thermodynamics and an excur
 sion into the UV - Basem El-Menoufi (University of Sussex)

CONTACT:Francesco Coradeschi
DESCRIPTION:Albeit great deal of work\, we are still far from 'the' quantu
 m theory of gravity. Yet\, the past few decades have seen a shift in the w
 ay the problem is viewed. It is by now clear that even though Quantum Gene
 ral Relativity is perturbatively non-renormalizable\, it is a well-behaved
  low-energy effective theory. In this talk\, I will discuss the EFT treatm
 ent of quantum gravity and some recent progress in "infrared quantum gravi
 ty". As an application\, I will focus on computing the partition function 
 of Euclidean quantum gravity utilizing the EFT techniques. I will re-inves
 tigate the question about the thermal stability of Schwarzschild black hol
 e\, when one takes into account the quantum corrections due to massless fl
 uctuations. Moreover\, the effective theory can tell us a great deal about
  the UV as well. I will show how one can obtain constraints on the UV comp
 letion of quantum gravity by a careful study of the logarithmic correction
  to Bekenstein-Hawking entropy.\n\nThe slides of the presentation can be f
