…a heavy, uncharged elementary particle considered to transmit the weak interaction between other elementary particles…
…a fast-moving electron emitted by radioactive decay of substances. (The emission of beta particles was originally regarded as a ray.)…
…a concentrated stream of subatomic particles, generated in order to cause collisions between particles that will shed new light on their nature and structure…
…a helium nucleus emitted by some radioactive substances, originally regarded as a ray…
…a preposition forming part of a title of the nobility (e.g. French de, German von)…
…the branch of physics that deals with the properties, relationships, and interactions of subatomic particles…
…a subatomic particle classified as having a nonzero value for strangeness…
…a particle smaller than an atom (e.g., a neutron) or a cluster of such particles (e.g., an alpha particle)…
…any of various fundamental subatomic particles, including those that are the smallest and most basic constituents of matter (leptons and quarks) or are combinations of these (hadrons, which consist of quarks), and those that transmit one of the four fundamental interactions in nature (gravitational, electromagnetic, strong, and weak)…
…an apparatus for accelerating subatomic particles to high velocities by means of electric or electromagnetic fields. The accelerated particles are generally made to collide with other particles, either as a research technique or for the generation of high-energy X-rays and gamma rays…
…an unstable subatomic particle of the lepton class, with a charge of 1 and a mass roughly 3,500 times that of the electron…
…a subatomic particle having the same mass as a given particle but opposite electric or magnetic properties. Every kind of subatomic particle has a corresponding antiparticle, e.g., the positron has the same mass as the electron but an equal and opposite charge…
…a subatomic particle whose existence is predicted by the theory that unified the weak and electromagnetic interactions…
…material made in rigid sheets or panels from compressed wood chips and resin, often coated or veneered, and used in furniture, buildings, etc., where a stronger material is not required…
…a meson thought to contain a b quark bound to its antiparticle, produced in particle accelerators…
