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.

Strings in magnetic fields in extra-dimensions and the Standard Model
Paolo Di Vecchia
I will start discussing the ideas presently used for connecting
string theory to particle phenomenology. They are based on the existence in
string theory of non-perturbative objects called D branes. I will give a brief
description of them. Then, in order to
be able to describe chiral matter as leptons and quarks, I will
introduce the magnetized D branes that have the property of having
magnetic fields living on the compact extra dimensions. I will then
determine the spectrum of open strings connected to D branes having
different magnetizations and I will show that this spectrum reduces,
in the field theory limit, to that of an electron in an external
magnetic field. The degeneracy of the Landau levels corresponds to
the different families of quarks and leptons. Finally, I will discuss the Kaluza-Klein
reduction of the low-energy effective action living on a stack of D9 branes and I will
show how to compute the parameters of the low-energy Lagrangian as
the Kähler metrics and Yukawa couplings that enter in the
determination of the
masses of quarks and leptons.
