Searching for new physics with beauty particles
A new LHCb analysis confirms a previously observed tension with the Standard Model, but more data and improved theoretical calculations are needed to determine whether new physics is at play
-
Shape-shifting collisions probe secrets of early Universe
The first high-energy collisions between light nuclei at the Large Hadron Collider confirm the unusual “bowling-pin” shape of neon nuclei and offer up a new tool to study the extreme state of matter produced in the aftermath of the Big Bang
-
ISOLDE investigates island of inversion
An experiment carried out at CERN’s ISOLDE facility has determined the western shore of a small island of atomic nuclei, where conventional nuclear rules break down
-
A quantum leap for antimatter measurements
Demonstration of first antimatter quantum bit paves the way for substantially improved tests of nature’s fundamental symmetries
-
ATLAS closes in on rare Higgs decays
The ATLAS collaboration finds evidence of Higgs-boson decays to muons and improves sensitivity to Higgs-boson decays to a Z boson and a photon.

A century of quantum mechanics
On 9 July 1925, in a letter to Wolfgang Pauli, Werner Heisenberg revealed his new ideas, which were to revolutionise physics
-
Elusive romance of top-quark pairs observed at the LHC
The CMS and ATLAS experiments at CERN’s Large Hadron Collider have observed an unforeseen feature in the behaviour of top quarks that suggests that these heaviest of all elementary particles form a fleeting union

LHCb weighs up the Z
New measurement of the mass of the Z boson showcases the Large Hadron Collider’s growing role in precision physics
-
ALICE eyes the cosmos
New data from the ALICE experiment, collected when no particle beams were circulating in the LHC during pauses in Run 2, may contribute to solving a puzzle surrounding cosmic muons

AI enhances Higgs boson’s charm
The CMS collaboration presents a new search for the decay of a Higgs boson into charm quarks, bringing physicists closer to unravelling how this unique particle endows matter with mass
