LHC at 10: the physics legacy

The LHC’s physics programme has transformed our understanding of elementary particles, writes Michelangelo Mangano.

All surprising discoveries were anomalies at some stage

Learning to love anomalies

The 2020s will sort current anomalies in fundamental physics into discoveries or phantoms, says Ben Allanach.

Rekindled Atomki anomaly merits closer scrutiny

A large discrepancy in nuclear decay rates has received new experimental support, generating headlines about the possible existence of a fifth force.

Rarest strange decay shrinks from sight

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.

Two muons emerge from a Bs → μμ decay candidate

CMS revisits rare and beautiful decays

For many years the search for its extremely rare decay to a μ+μ– pair was a holy grail of particle physics.

Between desert and swampland

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.

Muon g−2 collaboration prepares for first results

Fermilab's E989 experiment aims to improve experimental errors by a factor of four.

Mexico hosts dynamic LHCP week

Studies involving unusual signatures were popular at the Mexico conference.

Heavy ions and hidden sectors

The meeting was inspired by several recent proposals to take advantage of the unique environment of heavy-ion collisions at the LHC to search for new phenomena.
