Summary of new ATLAS results from LHCP 2020
25 May 2020 | By
The eighth annual conference on Large Hadron Collider physics (LHCP 2020) kicks off today in video-conference rooms around the world. This week-long event is usually an opportunity for physicists from around the world to meet in person and share the latest news from their LHC experiments. This year, due to the COVID-19 pandemic, the conference is being held online.
However, digital attendance does bring with it some advantages! The LHCP 2020 conference will likely see its greatest participation yet, as over 1200 physicists have registered.
Members of the ATLAS Collaboration will be among them, unveiling a wide range of exciting new results. Look forward to first-ever measurements new phenomena, novel searches for elusive supersymmetry particles and high-precision tests of the Standard Model.
Key results will be explored in ATLAS Physics Briefings, to be released throughout the conference. Check the LHCP 2020 tag for the latest updates.
