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
It is defined as the smallest and indivisible particle of matter. In Hindi and Bengali language paramanu refers to the atom. [1] In Jainism it is one of the two types of Pudgala (matter), the other being Skandha. [2] [3] It also helps to define smallest measure of space. All the Parmanus occupy exactly same amount of space.
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 Molecule is the smallest particle of matter into which a body can be divided without losing its identity. An Atom is a still smaller particle produced by division of a molecule. Rather than simply having the attributes of mass and occupying space, matter was held to have chemical and electrical properties.
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 ...
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 .
Many more types of subatomic particles have been found. Most such particles (but not electrons) were eventually found to be composed of even smaller particles such as quarks. Particle physics studies these smallest particles; nuclear physics studies atomic nuclei and their (immediate) constituents: protons and neutrons.
This particle was called the Higgs boson and could be used to test whether the Higgs field was the correct explanation. After a 40-year search, a subatomic particle with the expected properties was discovered in 2012 by the ATLAS and CMS experiments at the Large Hadron Collider (LHC) at CERN near Geneva, Switzerland. The new particle was ...
