The material for the tutorial can be downloaded here:

Once you have unpacked it, there are instructions either in the README file or in the fastjet-WW-tutorial.pdf file. Prior to the hand-on session you might want to install fastjet (easier to do it in the same directory) following the instructions from

  http://fastjet.fr/quickstart.html

The tutorial requires events file which I will circulate on a USB stick. If the internet connection is good enough, you can also get them by executing the "get-event-files.sh" script in the event-files directory
