Is beta decay a weak charge-current processes?

Click For Summary

Discussion Overview

The discussion centers around the classification of beta decay as a weak charge-current process, referencing a specific paper. Participants are attempting to clarify the definitions of charge-current and charge-neutral processes in the context of weak interactions.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant seeks to understand a paper and the classification of processes as charge-current or charge-neutral.
  • Another participant asserts that any process involving the appearance or disappearance of charged particles is classified as charge-current.
  • A further clarification is made that this classification pertains specifically to weak processes, excluding pair production and annihilation.
  • There is an acknowledgment that not all participants may have the same level of understanding, particularly those outside the field of particle physics.

Areas of Agreement / Disagreement

Participants express differing levels of understanding regarding the definitions of charge-current and charge-neutral processes, indicating that there is no consensus on the clarity of these concepts among all participants.

Contextual Notes

There may be limitations in understanding due to varying backgrounds in particle physics among participants, which could affect the interpretation of the paper and the definitions being discussed.

Im try to understand this paper

http://citeseerx.ist.psu.edu/vie...

and see if I correctly understand which processes are charge-current processes, and which are charge neutral, as listed in Figure 1. Thanks

Every process where charged particles appear or disappear is charged-current.

... you know what I mean.
Weak processes only of course, and pair production/annihilation does not count.

Yes, I know what you mean. My point is that someone who is not a particle physicist might not.
