¿Qué es la ANTIMATERIA?

The video introduces antimatter, explaining its properties and how it differs from ordinary matter. It covers the characteristics of particles, such as charge and lepton number, and describes how antimatter is created in particle accelerators and other sources. The annihilation process, where matter and antimatter meet and transform into other particles, is detailed. Finally, the video explores why matter is more prevalent than antimatter in the universe, despite both being present in equal amounts at the beginning of time.

Describe the role of leptons and baryons in the context of particle physics.

What is the significance of the lepton number and baryon number in particle interactions?
