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.

Azimuthal angular correlation between heavy-flavour decay electrons and charged hadrons in pp and Pb-Pb collisions ALICE

The measurement of heavy-flavour (charm and beauty) production in ultra-relativistic heavy ion collisions provides an important test of the parton energy loss mechanism and its predicted color charge and parton mass dependencies. One approach to study heavy-flavour production is the measurement of electrons from semi-leptonic decays of heavy-flavour hadrons (HFE).
With the ALICE detector at the LHC, the nuclear modification factor (RAA) and azimuthal anisotropy and elliptic flow (v2) of heavy flavour decay electrons have been measured to understand the interactions of c and b quarks with the medium. Further insight into the interaction of heavy quarks with the dense medium can be obtained by measuring azimuthal angular correlations of heavy-flavour decay electrons and charged hadrons in Pb-Pb collisions and comparing it with pp collisions. In this presentation, I will discuss the results from the HFE correlation measurements obtained with the ALICE detector.
