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.

Isospin symmetry is an almost exact property of the Standard Model. This happens because the difference between the up and down quark masses is much smaller than a typical hadronic scale and because QED radiative corrections are suppressed by the smallness of the electromagnetic coupling constant. For these reasons, most of the existing lattice QCD predictions for several physical quantities have been obtained by assuming exact isospin symmetry. With the increasing precision of both the experimental and theoretical determinations of quantities such as the Kl2 and Kl3 decay rates, a good control over isospin breaking effects is becoming phenomenologically relevant. In this talk I shall discuss a method to calculate on the lattice isospin breaking effects and, more generally, QED radiative corrections to hadronic matrix elements. I shall show numerical results for the charged-neutral pion and kaon mass splittings and discuss how the QED radiative corrections to the leptonic decay rate of a charged pseudoscalar meson can be calculated on the lattice by starting from euclidean correlators.
