Even among particle physicists, the exact definition of a particle has diverse descriptions. These professional attempts at the definition of a particle include: [7] A particle is a collapsed wave function; A particle is a quantum excitation of a field; A particle is an irreducible representation of the Poincaré group; A particle is an ...
A WISP (weakly interacting slender particle) is any one of a number of low mass particles that might explain dark matter (such as the axion) A GIMP (gravitationally interacting massive particle) is a particle which provides an alternative explanation of dark matter, instead of the aforementioned WIMP
In particle physics, an elementary particle or fundamental particle is a subatomic particle that is not composed of other particles. [1] The Standard Model presently recognizes seventeen distinct particles—twelve fermions and five bosons .
A subatomic particle is a particle smaller than an atom. Subcategories. This category has the following 8 subcategories, out of 8 total. B. Bosons (5 C, 37 P) E.
In the physical sciences, a particle (or corpuscule in older texts) is a small localized object which can be described by several physical or chemical properties, such as volume, density, or mass. [ 1 ] [ 2 ] They vary greatly in size or quantity, from subatomic particles like the electron , to microscopic particles like atoms and molecules ...
The peculiar wobble of a subatomic particle called a muon in a U.S. laboratory experiment is making scientists increasingly suspect they are missing something in their understanding of physics ...
Forget about summer school as a time to make up a flunked course, or get a requirement out of the way. For a group of students at Fermilab, summer school means learning about one of the most ...
In particle physics, a boson (/ ˈ b oʊ z ɒ n / [1] / ˈ b oʊ s ɒ n / [2]) is a subatomic particle whose spin quantum number has an integer value (0, 1, 2, ...). Bosons form one of the two fundamental classes of subatomic particle, the other being fermions, which have odd half-integer spin (1 ⁄ 2, 3 ⁄ 2, 5 ⁄ 2, ...). Every observed ...
