Quick Question about anti-particles.

  • Thread starter mr-tom
  • Start date
In summary, anti-particles are particles with the same mass as their corresponding particles, but with opposite electric charge and other quantum numbers. They can be created through high-energy collisions or the decay of certain particles. The existence of anti-particles is significant in understanding the symmetry of the universe and has practical applications in fields such as medical imaging and radiation therapy. While they have the same mass, they have different properties such as spin and can annihilate each other when they come into contact, releasing energy in the form of gamma rays. This process is important in understanding the early universe and the formation of matter.

Is it true that they have negative kinetic energy; wouldn't this mean that they have imaginary velocities? :confused:

I'm sure I've read this somewhere but I just need to confirm if it's true or not.

No, it's not true. They have positive energy and mass and real velocities.

They have opposite charge though
 

What are anti-particles?

Anti-particles are particles that have the same mass as their corresponding particles, but have opposite electric charge and other quantum numbers.

How are anti-particles created?

Anti-particles can be created through high-energy collisions, such as in particle accelerators, or through the decay of certain particles.

What is the significance of anti-particles in physics?

The existence of anti-particles is an important concept in understanding the symmetry of the universe and the behavior of particles at high energies. It also has practical applications in fields such as medical imaging and radiation therapy.

Do anti-particles have the same properties as their corresponding particles?

Anti-particles have the same mass as their corresponding particles, but they have opposite electric charge and other quantum numbers. This means they will have different interactions with other particles and have different properties, such as spin.

Can particles and anti-particles annihilate each other?

Yes, particles and anti-particles can annihilate each other when they come into contact, releasing energy in the form of gamma rays. This process is important in understanding the early universe and the formation of matter.
