The collaboration scoured four months of electron-positron collisions at SuperKEKB for evidence of invisibly decaying Z′ bosons.
Updated measurements by LHCb of the angular distributions of a rare neutral B meson decay add fresh intrigue to the flavour puzzle.
The LHC’s physics programme has transformed our understanding of elementary particles, writes Michelangelo Mangano.
The 2020s will sort current anomalies in fundamental physics into discoveries or phantoms, says Ben Allanach.
A large discrepancy in nuclear decay rates has received new experimental support, generating headlines about the possible existence of a fifth force.
The decay of the K-short to two muons is sensitive to contributions from yet-to-be discovered particles that are too heavy to be observed directly.
For many years the search for its extremely rare decay to a μ+μ– pair was a holy grail of particle physics.
Planck 2019 focused on the latest in beyond the Standard Model (SM) physics and ultraviolet completions of the SM within theories that unify the fundamental interactions.
Fermilab's E989 experiment aims to improve experimental errors by a factor of four.
Studies involving unusual signatures were popular at the Mexico conference.
