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.

Massive spin-2 theories and their application to the dark matter problem
The Standard Model of Particle Physics contains particles of spin 0, 1/2 and 1, which generally appear as both massless and massive. General Relativity (GR), our standard theory for gravity, describes a massless spin-2 field. In regard of completeness, a massive spin-2 field would therefore be a natural addition to these models. For a long time it was believed that consistent theories for massive spin-2 fields do not exist, but recently this problem was overcome. The consistent theory for interacting massless and massive spin-2 fields is a bimetric theory for gravity, i.e. it contains two tensor fields. One of these tensors is the physical metric giving rise to gravitational interactions, very much like in GR. The other field contains the massive spin-2 degrees of freedom whose presence could have interesting implications for cosmology. In this talk I will review bimetric theory and argue that the massive spin-2 particle could be a candidate for dark matter whose interactions with ordinary matter are automatically suppressed by the Planck scale.
