Just as the photon, Z and W ± bosons are superpositions of the B 0, W 0, W 1, and W 2 fields, the photino, zino, and wino ± are superpositions of the bino 0, wino 0, wino 1, and wino 2. No matter if one uses the original gauginos or this superpositions as a basis, the only predicted physical particles are neutralinos and charginos as a ...
Elementary particles are particles with no measurable internal structure; that is, it is unknown whether they are composed of other particles. [1] They are the fundamental objects of quantum field theory. Many families and sub-families of elementary particles exist. Elementary particles are classified according to their spin.
Quasiparticles Quasiparticle Signification Underlying particles Angulon Used to describe the rotation of molecules in solvents. First postulated theoretically in 2015, [1] the existence of the angulon was confirmed in February 2017, after a series of experiments spanning 20 years.
These elementary particles mediate the weak interaction; the respective symbols are W +, W −, and Z 0. The W ± bosons have either a positive or negative electric charge of 1 elementary charge and are each other's antiparticles. The Z 0 boson is electrically neutral and is its own antiparticle. The three particles each have a spin of 1. The W ±
Particulates or atmospheric particulate matter (see below for other names) are microscopic particles of solid or liquid matter suspended in the air.The term aerosol refers to the particulate/air mixture, as opposed to the particulate matter alone, [1] though it is sometimes defined as a subset of aerosol terminology. [2]
Particle with dimensions between 1 × 10 −7 and 1 × 10 −4 m. Note 1: The lower limit between micro- and nano-sizing is still a matter of debate. Note 2: To be consistent with the prefix “micro” and the range imposed by the definition, dimensions of microparticles should be expressed in μm. [1]
A nanoparticle or ultrafine particle is a particle of matter 1 to 100 nanometres (nm) in diameter. [1] [2] The term is sometimes used for larger particles, up to 500 nm, or fibers and tubes that are less than 100 nm in only two directions.
Quarks are massive particles of spin-1 ⁄ 2, implying that they are fermions. They carry an electric charge of − 1 ⁄ 3 e (down-type quarks) or + 2 ⁄ 3 e (up-type quarks). For comparison, an electron has a charge of −1 e. They also carry colour charge, which is the equivalent of the electric charge for the strong interaction.
