Is dark matter boson or fermion?

Known elementary particles of matter can be placed in one of two categories: fermions and bosons. So, electrons, quarks, and neutrinos are fermions, while photons and gluons are bosons. Within the standard model of particle physics, there are no bosons that would fit the bill for dark matter.

How do you tell if an atom is a boson or fermion?

If the spin is one-half integer, like the spin of the electron or the quark, then the particle is a fermion. If the spin is integer, such as zero or one or two, then the particle is a boson. An atom consists of a nucleus and orbiting electrons.

Are all particles bosons or fermions?

All observed elementary particles are either fermions or bosons. The observed elementary bosons are nearly all gauge bosons: photons, W and Z bosons and gluons. The only exception is the Higgs boson, which is a scalar boson.

What are the components of dark matter?

Most scientists think that dark matter is composed of non-baryonic matter. The lead candidate, WIMPS (weakly interacting massive particles), have ten to a hundred times the mass of a proton, but their weak interactions with “normal” matter make them difficult to detect.

Is there anti dark matter?

Originally Answered: Is there anti dark matter? Most probably not. In the Standard Model, only particles with electrical charge have antiparticles (which have the same mass and spin but opposite electric charge).

What’s the difference between fermions and bosons?

A fermion is any particle that has an odd half-integer (like 1/2, 3/2, and so forth) spin. Bosons are those particles which have an integer spin (0, 1, 2…). All the force carrier particles are bosons. The fermions were found to obey Pauli exclusion principle and obeyed Fermi-Dirac statistics.

Are mesons bosons?

Mesons are intermediate mass particles which are made up of a quark-antiquark pair. Three quark combinations are called baryons. Mesons are bosons, while the baryons are fermions. There was a recent claim of observation of particles with five quarks (pentaquark), but further experimentation has not borne it out.

Does the Higgs boson give the mass also to dark matter?

In the standard model the Higgs boson gives the mass to other particles, but in the Universe we know that the 80\% of mass is in form of dark matter, that is not constituted by known particles. The Higgs boson gives the mass also to the dark matter with the same mechanism?

How are scientists looking for dark matter?

There, scientists are looking for dark matter by trying to create it. In the LHC, protons are made to collide at extremely high energies, producing a shower of other particles. Sometimes those are exotic particles that scientists normally wouldn’t have access to, and the hope is that dark matter may be among them.

Is dark matter hot or cold?

Dark matter could be “hot” or “cold,” which has nothing to do with temperature but describes how fast it moves. It could exist in excited states, or have lower energies. “Famously there’s an embarrassing plethora of different hypothetical particles or sets of particles that dark matter could be,” Volkas tells us.

What gives the mass to other particles in the universe?

In the standard model the Higgs boson gives the mass to other particles, but in the Universe we know that the 80\% of mass is in form of dark matter, that is not constituted by known particles. The Stack Exchange Network
