Particle physics

Definition

Particle physics is the study of the elementary building blocks of matter and radiation and their interaction. The fundamental particles are summarised by the standard model. This includes leptons (such as the electron), the quarks that make up protons and neutrons, and gauge bosons, which mediate forces between the other particles.

    Early results from the COSINE-100 experiment—designed to test a much-debated claim of the detection of a dark-matter signal—show no indications of dark matter, providing evidence against the previous claim.

    The solutions adopted by the high-energy physics community to foster reproducible research are examples of best practices that could be embraced more widely. This first experience suggests that reproducibility requires going beyond openness.

    The weak interaction between the nucleus and the electrons in a chain of Yb isotopes is measured with tabletop atomic physics techniques. The dependence of the interaction strength on the number of neutrons confirms the prediction by standard model.

    The Large Hadron Collider has completed its second data-taking period. For the next two years, the accelerator will shut down and the experiments will undergo major upgrades. Here’s a take on our past achievements — and a preview of the future.

    Measurements of the strength of interactions between the Higgs boson and other particles test the current model of particle physics. A key part of this model has been confirmed by observing the most common decay of the Higgs boson.

    An ultrahigh-energy neutrino event detected with the IceCube detector in Antarctica, simultaneous and co-spatial with a multi-wavelength outburst of a blazar about 3 billion light years away, points unambiguously to lepto-hadronic cooling mechanisms in jetted active galactic nuclei.
