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.

Evidence for light by light scattering and search for axion like particle in ultraperipheral PbPb collisions1h
Light by light (LbyL) scattering is a very rare phenomena which proceeds, at leading order in
the fine structure constant, via virtual box diagrams involving electrically charged fermions
(leptons and quarks) or W bosons. The evidence for light by light scattering is provided
by exploiting the strong electromagnetic fields from ultraperipheral PbPb collisions. This
process has been proposed as a sensitive channel to study physics beyond the standard model
as the modifications of the LbyL scattering rates can occur if new heavy particles such as
magnetic monopoles, vector-like fermions or axion-like particles contribute. These searches
require the accurate estimation of the heavy ion (PbPb) data luminosity. This talk covers the
results of evidence for light by light scattering and emittance scan analysis of PbPb collisions
for luminosity measurement.
