Are Beta Particles Made of Electrons and Anti-Neutrinos?

Click For Summary
SUMMARY

A beta particle is definitively an electron, while beta decay also produces an antineutrino. During beta decay, a neutron transforms into a proton, resulting in the emission of both a beta particle (electron) and an antineutrino. The interaction between the electron and antineutrino occurs through the weak force, which governs their interactions. This process can be represented using Feynman diagrams, illustrating the role of virtual particles like the W boson.

PREREQUISITES
  • Understanding of beta decay and its mechanisms
  • Familiarity with weak force interactions
  • Knowledge of particle physics terminology, including beta particles and antineutrinos
  • Basic comprehension of Feynman diagrams and virtual particles
NEXT STEPS
  • Research the principles of beta decay in nuclear physics
  • Study the weak force and its role in particle interactions
  • Explore Feynman diagrams and their applications in particle physics
  • Learn about the properties and behavior of W bosons in weak interactions
USEFUL FOR

Students and professionals in physics, particularly those focused on nuclear and particle physics, as well as anyone interested in the fundamental interactions of subatomic particles.

Does a Beta(?) Particle as a whole, comprise electrons and anti-neutrino?? or just a electron??
 
Physics news on Phys.org
A beta particle consists of only an electron, but beta decay also produces an (electron?) antineutrino. I think.
 
Ok..
Do you mean that the nuclear decay is further followed by the decay of the radioactive emission?

and yes, i would also like to know that, what do we mean when we say that
"A weak force exists between a antineutrino and a electron in a beta particle and they interact with the same weak force"

I want to know what this interaction is all about..?(What happens during such 'interactions'?)
 
I haven't studied the weak force very rigorously, so I can't answer your second, but the first, I don't think so. Beta decay releases two things: a beta particle (electron) and an antineutrino.
 
A beta particle is an electron. They're simply two different names for the same thing.

In beta decay, a neutron changes into a proton, and an electron (beta particle) and antineutrino are created. The electron and antineutrino do not exist before the decay, inside the neutron or elsewhere.

Thanks!
Can you answer my second question about the beta particle and antineutrino interaction by weak forces??

Thanks man..! :D

Particles get destroyed and produced. There is no deeper level here, they just can do this, and there are equations which allow to calculate this.
It can be shown as Feynman graph with a virtual particle (the W boson) in between, but I doubt that this is what you are looking for.
