In 2023, the ALICE experiment was ready for their best year yet, until a mysterious signal threatened everything. As the LHC wraps up its 2025 lead-ion run, physicists recall how they worked together to solve the puzzle.
Building the parts for the Large Hadron Collider has presented challenges but taught many lessons for both particle physics laboratories and their industry partners.
The Positron Electron Project (PEP) collider at the Stanford Linear Accelerator Center produced its first collisions in 1979. All sorts of particles burst out, including the tau lepton, an ephemeral cousin of the electron.
Mesons. Bosons. Pions. Muons. Asparagus. Yes, asparagus. Physicists have spare time, too, and a few of them spend it in Fermilab's Garden Club, with roots almost as old as the lab itself.
Physics has demonstrated that the everyday phenomena we experience are governed by universal principles applying at time and distance scales far beyond normal human experience.
Street banners honoring nine of Berkeley Lab's Nobel Prize winners, originally installed along Telegraph Avenue in 2003, have been mounted on poles on Cyclotron Road leading to Berkeley Lab in honor of its 75th anniversary.
The sighting of Jupiter's moons by Galileo Galilei resonates through science and history. Using a handmade telescope in January 1610, Galileo confirmed the Copernican theory that the planets moved around the sun; the Earth was not the center of the solar system.
