What will happen when a particle collide with other particles' anti-self? For example, down quark with anti-up quark , up quark with positron etc
That is an extremely rare decay (about 10 decays in a billion). The most common decay is ##\pi^+ \to \mu^+ \nu## and ##\pi^- \to \mu^- \bar\nu## (probability of more than 99.98%).Garlic said:π± -> π0 + e± + electron neutrino/antineutrino
Matter and anti-matter are fundamental components of the universe. Matter is made up of particles such as protons, neutrons, and electrons, while anti-matter is made up of particles with the same mass but opposite charge. When matter and anti-matter come into contact, they annihilate each other and release a tremendous amount of energy.
Anti-matter can be created through high-energy collisions, such as those in particle accelerators, or through natural processes like radioactive decay. In most cases, equal amounts of matter and anti-matter are created, but due to the asymmetry in the laws of physics, there is an excess of matter in the universe.
Studying anti-matter can provide insights into the fundamental laws of physics and help us understand the origin and evolution of the universe. It also has practical applications, such as in medical imaging and cancer treatment.
One of the main challenges in studying anti-matter is its rarity. Anti-matter is difficult to produce and even harder to contain. It also annihilates upon contact with matter, making it challenging to study. Another challenge is the cost and complexity of the technology needed to create and study anti-matter.
While anti-matter has a high energy density, it is currently not a viable source of energy due to the challenges in producing and storing it. Additionally, the process of creating anti-matter requires more energy than it produces, making it an inefficient energy source.
