Non-analyticities in three-dimensional gauge theories
M. Asorey, D. Garcia-Alvarez, J. L. Lopez
Quantum fluctuations generate in three-dimensional gauge theories not only radiative corrections to the Chern-Simons coupling but also non-analytic terms in the effective action. W…

Some remarks on high derivative quantum gravity
M. Asorey, J. L. López, I. L. Shapiro
We analyze the perturbative implications of the most general high derivative approach to quantum gravity based on a diffeomorphism invariant local action. In particular, we conside…
