If baryon number is conserved, a baryon cannot decay into mesons only (it can decay into another baryon and mesons) as mesons have baryon number zero.lightoflife said:Also, does it mean that no experimental evidence shows that baryons can decay into mesons.
The law of baryon conservation states that the total number of baryons (protons and neutrons) in a closed system remains constant over time. This means that baryons cannot be created or destroyed, only converted into different forms.
The law of baryon conservation is important because it helps us understand the behavior and interactions of particles in the universe. It is a fundamental principle in the study of particle physics and is essential in explaining the stability of matter.
The law of baryon conservation is a specific case of the conservation of energy, as baryons are a form of matter and have energy associated with them. This means that the total energy of a closed system, including baryons, is also conserved.
According to current scientific understanding, the law of baryon conservation is considered to be a fundamental principle of nature and has been observed to hold true in all known physical processes. However, there are some theories that suggest it may not hold true in certain extreme conditions, such as in the early universe or within black holes.
The law of baryon conservation is tested and verified through various experiments and observations in particle physics. These experiments involve studying the behavior of particles and their interactions, and analyzing the energy and momentum of these particles before and after the interaction. If the total number of baryons remains constant, it provides evidence for the validity of the law of baryon conservation.
