The 17 pages that link to Baryon number, each with the reason it gives.

• Noether's theoremRelated: In idealized field theories, a global phase symmetry of quark fields yields baryon-number conservation.

• BaryonRelated: It distinguishes baryonic matter from mesons and tracks baryon–antibaryon balance.

• BaryogenesisBroader topic: Changing this number is necessary to create a net baryon excess from an initially symmetric state.

• Charge conjugationRelated: Charge conjugation reverses baryon number, unlike symmetries that leave this internal charge unchanged.

• AntiparticleRelated: A baryon and its antiparticle carry opposite baryon numbers.

• AntiprotonRelated: The antiproton has baryon number −1, opposite to the proton’s +1.

• Baryon asymmetryBroader topic: Creating a net excess requires processes that change the universe’s total baryon number.

• Proton decayRelated: Proton decay requires interactions that do not conserve this quantity.

• Charge conservationCompared with: Unlike electric charge, baryon number is an approximate symmetry that may not hold in all theories.

• Lepton numberRelated: It is the parallel matter-counting charge that electroweak processes violate with lepton number.

• LeptogenesisRelated: Sphaleron conversion creates baryon number from an asymmetry initially stored in leptons.

• Sakharov conditionsRelated: Its violation lets processes change the net baryon count from zero.

• StrangenessRelated: Like strangeness, it helps track quantum-number conservation in hadron reactions.

• Conserved quantityBroader topic: It is conserved in ordinary particle interactions, though its status in deeper theories is limited.

• AntineutronRelated: Its sign distinguishes the antineutron from the neutron despite both being electrically neutral.

• Weak hyperchargeCompared with: It is a global matter quantum number, unlike gauge hypercharge in the electroweak theory.

• B − LRelated: B − L subtracts this charge from lepton number.
