ALPHA experiment at CERN observes the influence of gravity on antimatter.
ALPHA experiment at CERN observes the influence of gravity on antimatter. In a paper published earlier this autumn in Nature, the ALPHA collaboration at CERN’s Antimatter Factory shows that, within the precision of their experiment, atoms of antihydrogen – a positron orbiting an antiproton – fall to Earth in the same way as their matter

Upstream Tracker closing completes installation of the LHCb Upgrade detector
Upstream Tracker closing completes installation of the LHCb Upgrade detector The UT sub-detector is located in front of the LHCb dipole magnet. The images included in this news were taken during the UT closing process around the LHC beam pipe. The UT plays an essential role in achieving the desired processing speed in the innovative

Ending the 2023 LHC run with heavy-ion collisions
Ending the 2023 LHC run with heavy-ion collisions The LHC schedule for 2023 has been revised following the emergence of a leak in mid-July. The decision was to stop the regular proton running this year and focus on the heavy ion physics that was already scheduled for the year-end. This was complemented by relatively brief

In discussion with Valentina Cairo
In discussion with Valentina Cairo Earlier this summer, the 2023 Young Experimental Physicist Prize of the High Energy and Particle Physics Division of the European Physical Society – for early career experimental physicists – was awarded to CERN staff physicist Valentina Cairo for her outstanding contributions to the ATLAS experiment: from the construction of the

DUNE and T2K gear up for next stage
DUNE and T2K gear up for next stage In the middle of the LHC ring, at the CERN Prevessin site, lies an experimental facility dedicated to particles that are but missing momentum to the four major LHC experiments. The Neutrino Platform, built as an extension of the SPS test beam area, hosts the R&D activities

Triggering in ATLAS in Run 3
Triggering in ATLAS in Run 3 The ATLAS collaboration recently celebrated its 30th anniversary following the submission of the experiment’s Letter of Intent in 1992 and has accomplished great achievements during these years. However, it is still a young experiment, with only 6% of the total data set acquired to date. During the LHC Long

The CMS Trigger System for Run 3
The CMS Trigger System for Run 3 Before the start of the LHC Run 3, CMS improved many aspects of its trigger system in order to boost the physics reach of the experiment. To select events of potential physics interest, the CMS trigger system divides the processing into two levels: the Level-1 trigger (L1T), implemented

First edition of the RD51 Micro Pattern Gaseous Detectors School at CERN.
First edition of the RD51 Micro Pattern Gaseous Detectors School at CERN. The first edition of the RD51 Micro Pattern Gaseous Detectors (MPGD) School was held at CERN from November 27th to December 1st, 2023. The school focused on state-of-the-art MPGD technologies with the goals of introducing newcomers to the field of MPGDs as well

A word from the DIRAC and Rucio Workshop 2023
A word from the DIRAC and Rucio Workshop 2023 DIRAC and Rucio are two software projects used for scientific computing. Both projects are led by CERN, and the EP department is one of the major contributors to both. DIRAC is used by CERN experiments such as LHCb, CLIC, FCC, NA62, and non-CERN experiments like Belle

All the Objects in the Universe (and Some Questions)
All the Objects in the Universe (and Some Questions) When astronauts look at the Earth from orbit, they are often awed by its beauty and isolation. They speak of the overview effect; a cognitive shift to a new larger perspective that gives context and meaning to their lives. For physicists, a similar, more abstract overview
