Join us on a journey to the smallest pieces of matter! Learn what is happening 100 meters below the
ground at the European Organization for Nuclear Research (CERN). In the Large Hadron Collider, with a circumference
of 27 kilometres, the experiments ALICE, ATLAS, CMS, and LHCb are running. The following
short video gives an impression of the start of a fascinating journey looking for the origin of mass,
Dark Matter, and new phenomena such as Supersymmetry or Extra Dimensions.
Particle Physics is exciting research! You can take your part in that research on the following pages. The analysis of data
samples that have been recorded in 2010 with the ATLAS detector is waiting for you. Under the
points in the main (upper) menu, you can choose between two different measurements with
original data from the ATLAS experiment . They are called W-path and Z-path. The processing of each
path requires about 90 minutes. There is a theoretical introduction at the beginning of each task.
This is followed by exercises and the actual measurement. Afterwards you can evaluate and
interpret your result.
Please choose the W-Path or the Z-Path above. Now do some 21st century particle physics!
