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 DIANA collaboration analyzed the K+ interactions in liquid Xenon at K+ momentum in the range 300 - 560 MeV/c. In the effective mass spectra of Ks and proton we observe a significant narrow peak at mass 1538 ± 2 MeV, which we identify as Theta+ pentaquark. For the next step we have examined pK+ effective mass. The scan conditions and cuts were as much as possible close to those in pKs analysis. The mass spectra in two data sets appeared to be very similar except Theta+ region, where a possible pK+ excess is compatible with zero. Therefore the observed peak is not a spurious structure created by systematics. We argue that it is a physical signal from the s-channel pentaquark baryon : K+n -> Theta+,Theta+ -> pK0. By comparing pKs and pK+ mass spectra, we tested the isospin I=0,1,2 hypotheses. We may conclude that Theta+ is most likely an isoscalar. The results of pK+ analysis are PRELIMINARY only. Currently we probe several intra nuclear cascade models and increase the statistics.
