The graviton's Compton wavelength is at least 1.6 × 10 16 m, or about 1.6 light-years, corresponding to a graviton mass of no more than 7.7 × 10 −23 eV/c 2. [18] This relation between wavelength and mass-energy is calculated with the Planck–Einstein relation , the same formula that relates electromagnetic wavelength to photon energy .
The graviton is a hypothetical particle that has been included in some extensions to the Standard Model to mediate the gravitational force. It is in a peculiar category between known and hypothetical particles: As an unobserved particle that is not predicted by, nor required for the Standard Model , it belongs in the table of hypothetical ...
A FIP (feebly interacting particle) is a particle that interacts very weakly with conventional matter and could account for dark matter; A LSP (lightest supersymmetric particle) is a particle found in supersymmetric models as a contender of WIMPs; Other hypothetical particles to explain dark matter include sterile neutrino and axions.
Disregarding the fact that it sounds more like a Decepticon than a theoretical particle, the long-hypothesized graviton is the only missing “force carrier” in today’s Standard Model of ...
Particle physics or high-energy physics is the study of fundamental particles and forces that constitute matter and radiation.The field also studies combinations of elementary particles up to the scale of protons and neutrons, while the study of combination of protons and neutrons is called nuclear physics.
Don Lincon, a senior scientist at the U.S. particle physics laboratory Fermilab, describes bosons as “puppies of the subatomic world” because you can have an unlimited number of bosons in the ...
The graviton is a hypothetical tensor boson proposed to be the carrier of gravitational force in some quantum theories of gravity, but no such theory has been successfully incorporated into the Standard Model, so the Standard Model neither predicts any such particle nor requires it, and no gravitational quantum particle has been indicated by experiment.
Scientists found the particle X(2370) by sifting through a decade of data made up of 10 billion samples and finding a candidate with an average mass of 2,395 MeV/c2, the expected mass of a glueball.
