Lesson: The Conservation of Baryon Number Physics

Students will be able to

• recall that the baryon number of a quark is ,
• recall that the baryon number of an antiquark is ,
• recall that the baryon number of all other elementary particles is 0,
• recall that the total baryon number of a composite particle is the sum of the baryon numbers of each component particle,
• recall that baryons have a baryon number of 1,
• recall that mesons have a baryon number of 0,
• determine the baryon number of a composite particle based on its composition,
• recall that baryon number is conserved in all interactions,
• identify interactions that are not possible because they do not conserve baryon number.
