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.

    Superdiffusive transport could have a crucial role in explaining the flat radio spectra of reaccelerated fossil electrons observed in clusters. Thus, a theory developed for heliospheric shocks can have a wide application in astrophysics.

    There is no single approach to the quantization of gravity. Rather, multiple models are based on various assumptions, and experimental tests of Planck-scale physics present a particular challenge.

    The strong force binds the constituents of nuclei together. Differences between the force's fundamental interactions and their mirror images were thought to have been observed in heavy-ion collisions, but new data challenge this picture.

    While axions remain elusive, the CERN Axion Solar Telescope has now reached the interesting region where physics beyond the standard model could be glimpsed.

    An enhanced production of particles with strange quarks has been observed in high-multiplicity proton–proton collisions — an important clue to understand how strange quarks form, and perhaps a hint of the quark–gluon plasma.
