In order to enable an iCal export link, your account needs to have an API key created. This key enables other applications to access data from within Indico even when you are neither using nor logged into the Indico system yourself with the link provided. Once created, you can manage your key at any time by going to 'My Profile' and looking under the tab entitled 'HTTP API'. Further information about HTTP API keys can be found in the Indico documentation.
Additionally to having an API key associated with your account, exporting private event information requires the usage of a persistent signature. This enables API URLs which do not expire after a few minutes so while the setting is active, anyone in possession of the link provided can access the information. Due to this, it is extremely important that you keep these links private and for your use only. If you think someone else may have acquired access to a link using this key in the future, you must immediately create a new key pair on the 'My Profile' page under the 'HTTP API' and update the iCalendar links afterwards.

Conformal symmetry places strong constraints on the form of correlation functions. In this talk, we review recent developments in conformal field theory (CFT) from the perspective of momentum space, which is natural for many applications including inflationary cosmology as well as for making connections with scattering amplitudes. We show how scattering amplitudes can be extracted from CFT correlators by taking a certain flat space limit, and how the double copy structure of amplitudes is then naturally inherited by CFT correlators. In particular, stress tensor correlators have poles whose residues correspond to gravitational scattering amplitudes, and these residues are a double copy of the analogous residues appearing in current correlators, which correspond to gauge theory amplitudes. The same also holds for mixed correlators featuring marginal scalars. In odd spacetime dimensions these residues are easy to extract, but in even dimensions correlators have branch cuts meaning a specific analytic continuation is required.
