In particle physics, which type of number identifies the baryon number of antibaryons?

In particle physics, baryon number is a quantum number that is assigned based on the type of particles involved. Baryons, such as protons and neutrons, have a baryon number of +1, while antibaryons, which are the counterparts of baryons, possess the opposite baryon number. Therefore, antibaryons have a baryon number of -1.

This concept arises from the conservation laws that govern particle interactions. Baryons contribute positively to the total baryon number of a system, while antibaryons reduce it, indicating their antimatter nature. Thus, the identification of antibaryons with a baryon number of -1 is essential in understanding how they relate to baryons and the overall conservation laws in particle physics.
