Baryon number - Wikipedia
In particle physics, the baryon number is a strictly conserved additive quantum number of a system. It is defined as = (¯), where is the number of quarks, and ¯ is the number of antiquarks.
重子数 - 百度百科
重子数是一个相加性量子数，在粒子物理学中，反应前后各粒子的重子数之和等于反应之后各粒子的重子数之和，这就是重子数守恒定律。
11.3: Particle Conservation Laws - Physics LibreTexts
Distinguish three conservation laws: baryon number, lepton number, and strangeness; Use rules to determine the total baryon number, lepton number, and strangeness of particles before and after a reaction; Use baryon number, lepton number, and strangeness conservation to determine if particle reactions or decays occur
Baryon number | physics | Britannica
Baryons are characterized by a baryon number, B, of 1. Their antiparticles, called antibaryons, have a baryon number of −1. An atom containing, for example, one proton and one neutron (each with a baryon number of 1) has a baryon number of 2. …
What are Baryons | Definition & Properties | nuclear-power.com
In particle physics, the baryon number denotes which particles are baryons and which particles are not. Each baryon has a baryon number of 1, and each antibaryon has a baryon number of -1. Other non-baryonic particles have a baryon number of 0.

2023年1月18日 · Conservation of Baryon Number. The baryon number, B, is the number of baryons in an interaction; B depends on whether the particle is a baryon, anti-baryon or neither Baryons have a baryon number B = +1; Anti-baryons have a baryon number B = –1; Particles that are not baryons have a baryon number B = 0
Particle Interactions and Conservation Laws - HyperPhysics
One of the most important of these is the conservation of baryon number. Each of the baryons is assigned a baryon number B=1. This can be considered to be equivalent to assigning each quark a baryon number of 1/3. This implies that the mesons, with one quark and one antiquark, have a baryon number B=0. No known decay process or interaction in ...

2022年2月8日 · Baryon Number. The baryon number, B, is the number of baryons in an interaction; B depends on whether the particle is a baryon, anti-baryon or neither. Baryons have a baryon number B = +1; Anti-baryons have a baryon number B = –1; Particles that are not baryons have a baryon number B = 0; Baryon number is a quantum number and is conserved in ...
Baryon Number -- from Eric Weisstein's World of Physics - Wolfram
A conserved quantum number defined by assigning to every baryon and B = -1 to every antibaryon. mesons and leptons are then assigned B = 0. A process or reaction of fundamental particles cannot occur if it changes the total baryon number of a system. For example, the process
The Conservation of Baryon Number - HyperPhysics
One of the conservation laws that we find is the conservation of baryon number, and it has had a profound effect on the nature of the universe. Baryons include the proton and the neutron as the lightest baryons, and then a large family of heavier baryons which will generally decay to neutrons and protons, like "water running downhill".
