Award season at the ATLAS Experiment

From detector development to detailed searches for new physics, ATLAS PhD students publish dozens of outstanding theses every year. Since 2010, a few have been celebrated at the annual ATLAS Thesis Awards.

Integrated fiducial cross sections times leptonic branching ratios

How strange is the proton?

What precision measurement of the inclusive W+, W− and Z/γ∗ production cross sections can tell us about the true nature of the proton.

Return of the top quark!

For the first time, ATLAS has measured the kinematics of the top quark and of the tt̅ system in 13 TeV events containing two charged leptons, two neutrinos and two jets (called “dilepton” events).

The Trouble with Terabytes

2016 has been a record-breaking year. The LHC surpassed its design luminosity and produced stable beams a staggering 60% of the time – up from 40% in previous years, and even surpassing the hoped for 50% threshold. While all of the ATLAS experiment rejoiced – eager to analyse the vast outpouring of data from the experiment – its computing experts had their work cut out for them.

Measuring the W boson mass

The ATLAS collaboration is now reporting the first measurement of the W mass using LHC proton-proton collisions data at a centre-of-mass energy at 7 TeV. The ATLAS result matches the best single-experiment measurement of the W mass performed by the CDF collaboration.
