Analyze the reaction in terms of constituent quarks

Click For Summary

Homework Help Overview

The discussion revolves around analyzing a particle reaction in terms of its constituent quarks, specifically focusing on the quantities of down (d), up (u), and strange (s) quarks involved before and after the reaction.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants are attempting to reconcile the reported quantities of quarks with the presence of strange quarks in the resulting particles. Questions are raised regarding the interpretation of the strange quark number and its implications for the reaction's feasibility.

Discussion Status

Some participants are exploring the implications of the strange quark number being zero despite the presence of strange quarks in the products. There is a mention of the net strange quark number remaining unchanged, which is presented as a point of clarification regarding the strong interaction involved in the process.

Contextual Notes

There appears to be confusion regarding the definitions and implications of quark numbers in the context of the reaction, particularly concerning the treatment of strange quarks.

Looks fine.
Thanks for your reply. The correct answer in the book is that there are 2d, 1u, and 0s quarks after the reaction. I understand that the strange number is zero but how can you say 0s if the 2 particles formed contain s quarks? Very confusing.
 
The net is zero: One strange, one antistrange. 1+(-1)=0. As that net number didn't change for any quark the process is possible via the strong interaction.
