Last night, and for the first time ever, the Large Hadron Collider
(LHC) collided protons at the record-breaking energy of 13 TeV. For now it's only 'test collisions' to set up especially those systems that protect the machine and detectors from particles that stray from the edges of the beam.
For groups involved in the LHC experiments, such as the chair for experimental particle physics at LMU, these first collisions represent a milestone towards the restart of the LHC. The beginning of real data taking and the continuation of the hunt for New Physics is planned for early June 2015.
