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.

Obtaining a coherent picture of Single Spin Asymmetries (SSAs) in hard processes has been a longstanding question in QCD.
A particularly puzzling phenomenon, which yet needs to be explained and which seems to persist in preliminary LHC measurements, is the inclusive production of polarized Lambda baryons from unpolarized protons. Experiments show large transverse polarizations, contradicting the expectation from Perturbative QCD that polarization should be small as proportional to both strong coupling constant and struck-quark mass.
In this talk we present a possible mechanism to interpret inclusive Lambda production based on the observations that: 1. A large SSA can be generated only by introducing a phase difference at the amplitude level; 2. Generalized Parton Distributions (GPDs) provide the theoretical tool to realize such a condition at leading twist.
