Today it’s exactly twelve years that I have my CERN account :)
I first got it on 8 March 2005 when starting my internship in the high-energy-physics group at the Niels Bohr Institute in Copenhagen, thereby laying the foundation of all that came afterwards … great people, great physics, great places … looking forward to more of all :)
Based on the submission date of the Letter of Intend, 1 October 1992, the ATLAS Experiment will turn 25 years this autumn and I will have the pleasure to organise a live event on the actual birthday as well as an internal celebration during the Bratislava ATLAS Week in October … while getting caught in this, I noticed that, based on this calculation, I have been with ATLAS for half of its life (and a third of mine) by then.
Today Maarten Boonekamp, whom I had the pleasure to work with for my master thesis, presented the latest update on the measurement of the W-boson mass with ATLAS. In fact a subject I wrote part of thesis about and had my name on a physics paper for the first time. Not yet the precision predicted in the paper, but it’s also not yet the stats and certainly not the centre-of-mass energy assumed therein. Yet it’s a competitive measurement (80.370 GeV ± 0.019 GeV) in full agreement with the Standard Model.
