Title: 
Testing Inflation after Planck and BICEP2
Abstract: 

An unprecedented opportunity to constrain the inflationary theory is
provided by the current flow of high accuracy astrophysical data,
among which are the Cosmic Microwave Background measurements.
This is however a challenging project given the size of the inflationary
landscape which contains hundreds of different scenarios.

In this talk I will show how the simplest models (the slow-roll single
field models with minimal kinetic terms) can be studied one
by one in a systematic way. By means of Bayesian inference and
model comparison methods, I will explain how these models can be ranked.
From the Bayesian evidences and complexities of ~ 200 inflationary models,
I will discuss which models are excluded and which are the best models of inflation.
In particular, I will comment on the recent B-modes detection by the BICEP2
experiment and on its implication for inflation and inflationary models if confirmed.
