Strong and weak interactions particles

Click For Summary

Discussion Overview

The discussion revolves around the interactions experienced by various particles, specifically focusing on strong and weak interactions. Participants are examining whether specific particles, such as electrons, bosons, quarks, and gluons, experience one or both types of interactions, or neither. The scope includes theoretical considerations and clarifications regarding particle physics within the framework of the Standard Model.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants propose that electrons experience both strong and weak interactions, while others suggest they only experience weak interactions.
  • There is a claim that bosons, depending on their type, may only experience weak interactions, particularly in the case of the Higgs boson, which does not interact with the strong force.
  • Down quarks are suggested to experience both strong and weak interactions, while gluons are identified as carriers of strong interactions.
  • Anti muon neutrinos are noted to experience weak interactions.
  • Some participants express uncertainty about the interactions of bosons, particularly regarding their mass and the implications for their interaction types.
  • Clarifications are made regarding the general term "boson," which encompasses various particles, including those that may interact electromagnetically or via the strong force depending on their properties.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the interactions of bosons, with differing views on whether they can experience strong interactions. There are multiple competing views regarding the interactions of specific particles, particularly bosons and their classifications.

Contextual Notes

Participants note that the interactions depend on the specific type of boson and its transformation properties under symmetry groups, indicating a complexity in categorizing interactions that may not be fully resolved in the discussion.

Does anybody could help me to state if the following particles experience strong interactions, weak interactions, both interactions or neither of the two interactions? This is what I think:

electron = strong interactions and weak interactions
boson = weak interactions
down quark = strong interactions and weak interactions
gluon = strong interactions
anti muon neutrino = weak interactions
up antiquark = strong interactions

Thanks!

electron-weak W
boson-S and W
down quark=S and W
gluon- S
any neutrino W
any quark or antiqurk S and W
 
Thanks! I am just not sure that bosons are a quanta that experiences also in strong interactions. I thought that because they have a mass of about 80 or 90 GeV/c2, which is just less than the strength of weak interactions, they are emitted only during weak interactions. And because the strength of strong interactions is instead 10 times greater (about 1015 GeV), according with the theory of quantum chromodynamics during strong interactions it is involved the emissions of gluons, which is indeed the quanta for strong interactions.
 
Of course it depends on what type of boson you are talking about but if we only include standard model higgs bosons then it does not interact with the strong force. This is because the higgs transforms as a singlet under SU(3) and therefore does not interact with gluons.
 
"Boson" is a general term that includes any integral spin particle, so a Boson could be a gluon, pion, or a myriad of other particless.
 
Right, I was just trying to be specific because if we include pions as well then these bosons can interact electromagnetically, it all depends on how the Boson transforms under the appropriate symmery group.

There are also "gauge bosons" which are the "force carriers". Orion78 was there a specific particle/Boston you are interested in?
