A communication resource from the world's particle physics laboratories.
Theoretical physicists at the U.S. Department of Energy's (DOE's) Brookhaven National Laboratory and their collaborators released the most precise prediction of how subatomic particles called muons—heavy cousins of electrons—"wobble" off their path in a powerful magnetic field.
The Dark Energy Survey has made over 38,000 single exposure images and nearly 62,000 coadd images, along with related data, public. This data reveals nearly 310 million galaxies and 80 million stars to the public eye. Approximately 400 million astronomical objects are meticulously cataloged in the data for everyone to view.
Dive into the Data
Vital components of the DUNE detectors have been constructed in the UK and have now been shipped to CERN for initial testing, marking a significant milestone for the experiment’s progress.
The new CERN-MEDICIS facility is producing radioisotopes for medical research. These radioisotopes are destined primarily for hospitals and research centres in Switzerland and across Europe. MEDICIS will enable researchers to devise and test unconventional radioisotopes with a view to developing new approaches to fight cancer.
In its final years of operation, a particle collider in Northern California was refocused to search for signs of new particles that might help fill in some big blanks in our understanding of the universe.
A fresh analysis of this data, co-led by physicists at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab), limits some of the hiding places for one type of theorized particle – the dark photon, also known as the heavy photon – that was proposed to help explain the mystery of dark matter.
The latest result, published in the journal Physical Review Letters by the roughly 240-member BaBar Collaboration, adds to results from a collection of previous experiments seeking, but not yet finding, the theorized dark photons.
New result rivals precision of cosmic microwave background measurements, supports view that dark matter and dark energy make up most of the cosmos.
Imagine planting a single seed and, with great precision, being able to predict the exact height of the tree that grows from it. Now imagine traveling to the future and snapping photographic proof that you were right . . .
With the turning of a shovelful of earth a mile underground, a new era in international particle physics research officially began Friday, July 21.
In a unique groundbreaking ceremony held at the Sanford Underground Research Facility in Lead, South Dakota, a group of dignitaries, scientists and engineers from around the world marked the start of construction of a massive international experiment that could change our understanding of the universe. The Long-Baseline Neutrino Facility (LBNF) will house the international Deep Underground Neutrino Experiment (DUNE), which will be built and operated by a group of roughly 1,000 scientists and engineers from 30 countries.

This year, October 31 was more than just Halloween. It was also the first global celebration of Dark Matter Day. In 25 countries, 11 US states and online, people interacted with scientists, watched demonstrations, viewed films, took in art exhibits and toured laboratories to learn about the ongoing search for dark matter.
Symmetry has collected a series of photos from participants around the world. Check out how people celebrated Dark Matter Day and download a commemorative dark matter poster (to be printed using visible matter).
This report distills the findings of a series of international peer reviews of the communications and outreach functions of large-scale multidisciplinary science laboratories around the world.
