The 41st annual IAP Colloquium aims at providing an overview of research on cosmological inflation. This field is in full swing, with numerous emerging research themes, on theoretical, computational and observational grounds. Two main axes can be distinguished: precision physics, aiming to probe inflation on cosmological scales (with CMB and LSS observations), searching for fine effects such as primordial features and non-Gaussianities, effectively using inflation as a giant particle collider, and more generally as a laboratory for fundamental physics. The other axis concerns more exploratory physics: through the study of the stochastic gravitational-wave background and primordial black holes, gravitational-wave astronomy allows us to probe the late stage of the inflation, the physics of which is completely unknown.
The colloquium will bring together theoreticians, computational physicists and observers to review recent progress and open questions pertaining to the field, notably concerning the cosmological collider, cosmological bootstrap, non-perturbative formalisms, loop effects, open effective theories, constraints from the CMB and the Large-Scale Structure, field-level inference, gravitational-wave backgrounds, primordial black holes, simulations of inflation.
Invited speakers (preliminary list): Adam Andrews, Josu Aurrekoetxea, Matteo Braglia, Cliff Burgess, Angelo Caravano, Thomas Colas, Fabio Finelli, Jacopo Fumagalli, Juan Garcia-Bellido, Gonzalo Palma, Olvier Philcox, Shi Pi, Yuko Urakawa, Zhong-Zhi Xianyu, David Wands.
Registration: the number of on-site participants is limited to 130 due to the capacity of the amphitheatre. Participation in this event is thus moderated. The deadline for registration and submission of an abstract for a contributed talk or a poster is September 28. Acceptance will be decided by October 3, after which payment of registration fees should be done before Oct 17, following the instructions that will be given to accepted participants. Contributed talks last 20 mins including questions and are only for on-site participants.
Registration fees of 300 euros cover a welcome cocktail, coffee breaks and a dinner cruise on the Seine. Registration fees for online participants amount to 50 euros.
Conference dinner: we will have a dinner cruise on the Seine on Wednesday 3rd, from 8.15pm to 11pm, aboard the Capitaine Fracasse.
