Given the above axion mass range, we further pin down the dark-sector particles to consist of only one species of fermion and anti-fermion, likely right-handed neutrinos. A positive kaon (K^+) has a rest mass of 494 MeV whereas a proton has a rest mass of 938 MeV. This is equivalent to 1.6 x 10-19 coulombs Spin is the internal angular momentum of a particle.

Calculate the mass in GeV/c2 of a virtual carrier particle that has a range limited to 10−32 m by the Heisenberg uncertainty principle. The preferred mass range is around 10 GeV, with a quite large spin-independent cross section of $10^{-43}$-$10^{-41}\,{\rm cm^2}$. At the time it was first detected, the mass of the Higgs boson was measured as roughly 125 to 126 Gigaelectronvolts (GeV). A particle has a total relativistic energy of 10 GeV and a relativistic momentum of 8 GeV/c. Such a particle might be involved in the unification of the strong and electroweak forces. Calculate the mass in GeV/ c 2 of a virtual carrier particle that has a range limited to 10-30 m by the Heisenberg uncertainty principle. What is its energy and speed? A particle has a speed of 0.92c has a momentum of is its mass? Such a particle might be involved in the unification of the strong and electroweak forces.

These couplings are usually called the Higgs–Yukawa couplings, and they vary slowly as the energy scale at which they are measured is varied, due to a quantum effect called the renormalization group . A nuclear particle has mass 3 GeV/c^2 and momentum 4 GeV/c. 3.

With a mass around $92-128$ eV, the dark-sector particles may constitute a minority population of dark matter. Electric charge is given in terms of the charge of a proton, which is +1.

Calculate the momentum, kinetic energy, and total energy of an electron travelling ata speed of a) 0.01c, 0.1c, and 0.9c. Related Questions. 1GeV is about the amount of energy required to create a proton, because the mass of a proton is 0.938GeV/c 2 = 1.67 x 10-27 kg. What particle has the most mass? The top quark, with a mass of 173,1 ± 1,3 GeV/c2.

Another component of the strong nuclear force is transmitted by the exchange of virtual K-mesons. What is its mass? At what speed would a body's relativistic energy be twice its rest energy? It is given by h/2pi where h is Planck's constant.

What is the rest mass of this particle in GeV?

Wiki User 2009-08-07 20:43:09. 2. 10^-16 kg.m/s. These assumptions also set the axion decay constant scale to several $\times 10^{16}$ GeV. A low-mass particle, such as the electron has a minuscule coupling = × −, while the top quark has the largest coupling to the Higgs, ≃. In this paper, we recall that a light dark matter particle with dominant couplings to quarks should also generate cosmic-ray antiprotons.
