On UltraViolet effects in protected inflationary models
  Inflationary models are usually UV sensitive. Several mechanism have been
proposed to protect the necessary features of the potential, and most notably
(softly broken) global symmetries as shift-symmetry. We show that, even in
presence of these protecting mechanisms, the models maintain a serious
UV-dependence. Via an improved effective theory analysis, we show how these
corrections could significantly affect the duration of inflation, its
robustness against the choice of initial conditions and the regimes that make
it possible.
