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.

The difference in CP violation between the D0→K+K– and D0→π+π– decays (ΔACP) has emerged as an interesting observable to search for matter-antimatter asymmetries in the charm sector. By taking the difference between the two modes, most of the asymmetries induced by the detector or coming from the production mechanism cancel. A previous LHCb measurement, using 0.6 fb–1 of data, gave 3.5σ evidence for CP violation in the charm sector, which was further strengthened by results from the CDF and Belle collaborations. We present an update of the ΔACP measurement, consisting of two independent analyses, both using the full 2011 data set of 1.0 fb–1. In the first, the initial flavour of the D meson (D0 or D0-bar) is inferred from the charge of the slow pion in the decay D*+→D0π+, as in the previous publication. The second uses D mesons produced in semileptonic B decays, where the charge of the associated muon provides the tag.
