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 LHCb Collaboration has recently observed evidence of CP violation in neutral D meson decays. CP violation in the charm sector is generically expected to be very small in the Standard Model, but can be enhanced in many models of new physics. In this seminar we will present the results of a search for time-integrated CP violation in D0 -> h- h+ (h=K,pi) decays, performed with around 0.6 fb-1 of data collected by LHCb in 2011. The difference in CP asymmetry between D0 -> K- K+ and D0 ->pi- pi+, Delta A_CP = A_CP(K- K+) - A_CP(pi- pi+) is measured to be Delta A_CP = [-0.82 +- 0.21 (stat.) +- 0.11 (syst.)]%. This differs from the hypothesis of CP conservation by 3.5 sigma. Prospects for improved measurements of this quantity and other CP-violating observables in the charm sector will be briefly discussed.
