A new and surprising duality has been found in theoretical particle physics. The duality exists between two types of scattering processes that can occur in…
Beams of protons are again circulating around the collider’s 27-kilometer ring, marking the end of a multiple-year hiatus for upgrade work. In 2022, CERN is…
Recently at the Quark Matter conference and before that at the Rencontres de Moriond conference, the Large Hadron Collider beauty (LHCb) collaboration presented an analysis of…
Precise knowledge of the top-quark mass is of paramount importance to understanding our world at the smallest scale. The Compact Muon Solenoid (CMS) collaboration at…
New ATLAS and CMS analyses place tight limits on the strength of the Higgs boson’s interaction with the charm quark. Since the discovery of the…
Physicists at the ATLAS experiment are on the hunt for new, long-lived particles to help explain several outstanding mysteries of our Universe. Physicists at the…
The collaborations have set stringent new bounds on the fraction of Higgs bosons transforming into invisible particles. The Higgs boson lives for an extremely short…
The result may open doors to several lines of research in particle physics and beyond. A hybrid matter–antimatter helium atom containing an antiproton, the proton’s…
New results from the LHCb experiment on CP asymmetry in charmless three-body charged B meson decays include the largest CP asymmetry ever observed. CP asymmetry…
While data processing demand is rocketing for LHC’s Run 3, the four large experiments are increasing their use of GPUs to improve their computing infrastructure….
A duo of theorists proposes a new theory to explain both the surprisingly small mass of the Higgs boson and the puzzling symmetry properties of…
The findings could redefine the kinds of particles that were abundant in the early universe. In the first millionths of a second after the Big…
While the Large Hadron Collider (LHC) is well known for smashing protons together, it is actually the quarks and gluons inside the protons – collectively…
The ATLAS Experiment at CERN welcomes a brand-new detector: the Muon New Small Wheel system. Its successful installation follows nearly a decade of design and…
The ALICE collaboration has for the first time observed the residual strong interaction between protons and phi mesons. In an article recently published in Physical…
Scientific first at CERN facility a preview of upcoming 3-year research campaign. The international Forward Search Experiment team, led by physicists at the University of…
In a first for particle physics, the CMS collaboration has observed three J/ψ particles emerging from a single collision between two protons. It’s a triple…
