7th April 2020 – Two years ago, the Higgs boson was observed decaying to a pair of beauty-quarks (H→bb), moving its study from the “discovery era” to the “measurement era”. In new results presented today, the ATLAS Collaboration studied the full LHC Run-2 dataset to give an updated measurement of H→bb, where the Higgs boson is produced in association with a vector boson (W or Z).
2nd April 2020 – The global health crisis caused by COVID-19 has impacted every aspect of life. Much of the world’s population are sheltering in place, with ATLAS Collaboration members similarly affected.
11th March 2020 – At an award ceremony in the Globe of Science and Innovation, the ATLAS Collaboration celebrated the new recipients of the ATLAS PhD Grant: Prajita Bhattarai, Hassnae El Jarrari and Albert Kong.
3rd March 2020 – With over 5000 members in 181 institutions, contributions to the ATLAS Collaboration can take a variety of forms. Every February, ATLAS celebrates the outstanding work of one particular set of members: its PhD students.
28th February 2020 – In 2019, I joined the ATLAS Early Career Scientist Board (ECSB): a special advisory group dedicated to assisting the ATLAS Collaboration in building an environment where the full scientific potential of scientists at the start of their career can be realised. The board organises several activities for the ATLAS community (you may have seen all of our summer activities described in this blog). I was actively involved in the winter activities. They were all fantastic experiences to improve social relationships in a 5000-people collaboration.
21st February 2020 – A quarter-century after its discovery, physicists at the ATLAS Experiment are gaining new insight into the heaviest-known particle: the top quark. The huge amount of data collected during Run 2 of the LHC (2015-2018) has allowed physicists to study rare production processes of the top quark in great detail, including its production in association with other heavy elementary particles.
18th February 2020 – In new results presented today at CERN, the ATLAS Experiment’s search for supersymmetry (SUSY) reached new levels of sensitivity. The results examine a popular SUSY extension studied at the Large Hadron Collider (LHC): the “Minimal Supersymmetric Standard Model” (MSSM), which includes the minimum required number of new particles and interactions to make predictions at the LHC energies.
10th February 2020 – The ATLAS Collaboration at CERN has just released the first open dataset from the Large Hadron Collider’s (LHC) highest-energy run at 13 teraelectronvolts (TeV). The new release is specially developed for science education, underlining the Collaboration’s long-standing commitment to students and teachers using open-access ATLAS data and related tools.
14th January 2020 – Philippe Farthouat has played a critical role in electronics development since the beginning of ATLAS, from design and prototyping to testing and installation. He has been the overall ATLAS electronics coordinator since 1999.
22nd December 2019 – This past week, I grabbed a last-minute opportunity to wander about and take in the beauty of my favourite particle physics detector. Located 100 meters under the French/Swiss border near Geneva, ATLAS is always a marvel to see and to explore. Although I have hosted hundreds of visits by its side, I never tire of the view and inevitably pull out my phone or camera to photograph it, yet again.
