Discussion Overview

The discussion centers around the role of the electro-weak force in the context of lepton scattering from hadrons, particularly in collider experiments. Participants explore whether the electro-weak force acts as an intermediate force that facilitates the production of new hadrons through its interaction with leptons.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant suggests that the electro-weak force is responsible for exciting hadrons during lepton scattering, potentially leading to the production of new hadrons.
  • Another participant points out that most modern colliders operate on lepton-lepton or hadron-hadron interactions, with the exception of HERA, which is a lepton-hadron collider.
  • This participant also clarifies that the initial interaction in such collisions can be electromagnetic or weak, and that the energy from these collisions contributes to the production of additional particles.

Areas of Agreement / Disagreement

There is no clear consensus on the role of the electro-weak force as an intermediate force in hadron production, and the discussion includes varying levels of understanding and clarity among participants.

Contextual Notes

Some participants express difficulty in understanding the original post due to language barriers, which may affect the clarity of the discussion. Additionally, the complexity of the topic may contribute to the lack of responses.

Who May Find This Useful

This discussion may be of interest to individuals studying particle physics, particularly those exploring the interactions between leptons and hadrons in collider experiments.

Please teach me this:
In collider of lepton scattering from hadron,I think that the electro-weak force is interaction between lepton and hadron, then hadron being excited,because of this inducing the strong force has an effect of producing new hadrons(if possible).So that electro-weak force is ''intermediate force'' in producing new hadrons.Is that correct?
Thank you very much in advance.

I have noticed many posts like this from you recently. I suspect that there are two reasons why you get very few replies. The topics are very advanced, and your English is very, very difficult to understand. I'm sorry to say this, but I can't figure out what you are talking about.
 
I am grateful very much for the Physics Forum.In Vietnam I have to self-study Physics and English.The Forum has really helped very,very much.
 
ndung200790, I think I can figure out what you're asking, please correct me if I'm wrong.
In collider of lepton scattering from hadron
Most colliders these days are lepton-lepton (LEP) or hadron-hadron (Tevatron and LHC) colliders. The only lepton-hadron collider in the world is HERA at DESY, which collides 30 GeV electrons/positrons with 920 GeV protons.

As you see http://www.pd.infn.it/~longhin/tesidott/html/node3.html" , you are correct: the initial interaction is either electromagnetic (photon) or weak (W or Z). From that point on, the energy from the collision goes into the production of additional particles, both hadrons and leptons.
