baryon number

Particles without any quarks have a baryon number of zero.

Baryon number conservation is more fundamental than the first and second laws of thermodynamics.

Electroweak sphalerons can only change the baryon number by 3.

Other conserved quantities like baryon number are the same.

The baryon number is conserved in nearly all the interactions of the Standard Model.

He proposed the law of conservation of baryon number.

Three antiquarks into an antibaryon with baryon number 1.

The universe, as a whole, seems to have a nonzero positive baryon number density - that is, matter exists.

If so, they would induce baryon number violation.

Of these chiral symmetries, the baryon number symmetry is exact.

In particle physics, the 'baryon number' is an conservation laws quantum number of a system.

They are color-triplet bosons that carry both lepton and baryon numbers.

Baryon number is violated, but only at very small scales, and the proton has a very long lifetime.

Protonium is an electrically neutral boson with zero baryon number.

Baryon number violation is obviously a necessary condition to produce an excess of baryons over anti-baryons.

All of these can be classed as mesons, because they are hadrons and carry zero baryon number.

All particles within a multiplet, have the same spin, parity, and baryon numbers, but differ in electric charges.

Typical internal symmetries are lepton number and baryon number or the electric charge.

In 1970, he proposed neutron/antineutron oscillations as a possibility for observing violation of baryon number.

Baryons have a given Baryon number.

Mesons are hadrons with zero baryon number.

To the above equations, a statement of conservation is usually added, usually conservation of baryon number.

Weak hypercharge is related to baryon number - lepton number via:

Baryon number violation.
