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.
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.
A field configuration is topologically non-trivial if it exhibits the topology of a “mathematical knot” in some space, real or otherwise.
The open symposium of the European Strategy for Particle Physics revealed a vibrant field in flux as it grapples with the next big questions.
At the European Strategy for Particle Physics, talks covered key questions in the field, and the accelerator, detector and computing technologies necessary to tackle them.
