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.

Electromagnetic form factors give Lorentz invariant information about the electromagnetic charge distributions inside hadrons. They are thus a key probe of the dynamics of QCD in the low energy, non-perturbative regime. Importantly, it is well known that due to its characteristically light mass, the pion plays an important role in low energy observables. In particular, the effects of implementing pion loop corrections at the hadron level (as opposed to the quark level) will be discussed. I will show results for electromagnetic form factors calculated in the NJL Model, and in particular, that one obtains am improved prediction of the predicted Hyperon Magnetic moment when the pion loop effects are implemented in this way. One important input into this calculation is the pion form factor itself. Modern extractions of the pion form factor for moderate values of the photon virtuality (above about 0.3 GeV^2) arise from a model dependent extraction from pion electro-production data. In the second half of the talk, a simple model of pion electro-production, will be described and used to examine the model dependence of the extraction method. In the context of this simple model, the extracted form factor is systematically overestimated.
