Discussion Overview

The discussion revolves around whether all particles, including pions, kaons, and tau particles, carry the elementary charge of ±e. It explores the charge properties of various particles, including their quark structures and the implications for their overall charge.

Discussion Character

  • Debate/contested

Main Points Raised

  • Some participants propose that the electric charge of particles can be determined by examining their quark structure, suggesting that quarks have a total electric charge of "e" in absolute value.
  • Others argue that the tau particle, being a lepton, does not have an inner quark structure and carries a charge of -1, unlike other particles.
  • It is noted that pions can have three possible charges: +1, 0, and -1, indicating that not all particles carry the elementary charge of ±e.
  • Participants mention baryons that can have charges of 2 or 3, with examples like the Δ baryons and others such as sigma and lambda particles being referenced.
  • One participant expresses surprise at the existence of baryons with higher charges and seeks clarification on specific examples.

Areas of Agreement / Disagreement

Participants do not reach a consensus on whether all particles carry the elementary charge of ±e, as multiple competing views regarding the charge properties of different particles are presented.

Contextual Notes

The discussion highlights the complexity of particle charge properties and the dependence on quark structure, but does not resolve the implications of these factors on the overall question.

Do all particles like pions, kaons, sigma, tau, whatever, all carry the elementary charge +-e ?
 
Physics news on Phys.org
If the quark inner structure has total electric charge "e" in absolute value,then,yes...

Search for their quark structure.It's the only way to determine their electric charge.

Well, the tau is a lepton... with no inner quark structure, with a charge (like all leptons, besides for all the neutrinos partners) of 1-.
 
pions are found with three possible charges: +1, 0, -1. Also there are baryons with charges of 2 or 3.

Really? Which? I only know of protons and neutrons.
 
I vaguely remember in the [itex]\Delta[/itex] decaplet this object
[tex]\Delta^{++}[/tex]

So that's an example.You can search for more.

Wow thanks, I searched and came up with many more, there are your deltas, as quasar said the sigmas, lambda, Xi Cascades etc.
Check this out if you want
