Understanding W-Boson Decay: Electron & Anti-Neutrino Formation

Click For Summary

Discussion Overview

The discussion centers around the decay of the W-boson into an electron and an anti-neutrino, exploring the underlying mechanisms and conditions that allow this process to occur. It touches on concepts related to particle interactions, conservation laws, and the context of beta decay.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification, Debate/contested

Main Points Raised

  • Some participants propose that the W-boson decays into an electron and anti-neutrino because it is allowed by the symmetries of particle interactions.
  • Others argue that the decay conserves all relevant quantities, although specifics on these quantities are not detailed.
  • A participant expresses confusion regarding beta decay, specifically the transformation of a proton into a neutron, questioning how a lighter proton can decay into a heavier neutron.
  • Another participant clarifies that a proton cannot decay into a neutron without additional energy input from the environment, suggesting that the decay process involves interactions that allow for energy conservation.

Areas of Agreement / Disagreement

Participants express differing views on the conditions necessary for W-boson decay and the mechanics of beta decay, indicating that multiple competing perspectives remain without consensus.

Contextual Notes

The discussion includes assumptions about energy conservation and particle interactions that are not fully explored, leaving some steps and definitions unresolved.

How W- boson decay into electron and anti neutrino?
 
Physics news on Phys.org
Well it depends on what you find as a satisfying answer. I'd say that it decays into such, because "it can" . It's allowed to (due to the symmetries) interact/couple with those particles and so it does.

+ the ( W-> e nu ) is conserving all the quantities we think that are conserved.

P.S. - the title of the thread is misleading, you should try to write a title that represents clearly your question.
 
Thank...basically I m confused in beta decay.in which proton is transformed into neutron.as we know that proton is lighter then neutron.
 
And that actually means that a proton by itself cannot decay to a neutron (what I'm saying is that the proton decay is not an 1->3 particle decay).
In fact it needs to be able to drain energy from the environment so that is to say the decay is actually of the form:
[itex]p e^- \rightarrow n \nu[/itex]
or having something else:
[itex]X p \rightarrow X n e^+ \nu[/itex]
So a 1+(1)->3+(1) which can energetically allow it.
 
Thanks
