    Basics Theory
Click For Summary
The Cabibbo theory quantifies the coupling strengths between different generations of quarks, specifically focusing on the up (u), down (d), and strange (s) quarks. This theory was later expanded by the GIM mechanism, which introduced the charm (c) quark to explain certain particle decay processes. The CKM matrix further extends Cabibbo and GIM theories to include all three generations of quarks. The initial understanding of the Cabibbo angle as a measure of these coupling strengths is accurate. Overall, the discussion clarifies the foundational aspects of Cabibbo theory and its significance in particle physics.

Hi,

I'm trying to cover the basics of Cabibbo theory, yet the materials I've been presented with give a very jumbled description, and I'd just like to ask here to obtain some clarity...

Is it fair to say that the Cabibbo angle is a means of quantifying the different coupling strengths between different generations of quarks?

Or is this too much a simplification or just plain ol wrong?

Regards

Luke

That is exactly what the cabibo angle is for. Cabbibo theory accounts only for the u d and s quarks. This was extended my the GIM mechanism which proposed the c quark to account for K0 -> mu+ mu - supression; And the CKM matrix extends the same (Cabbibo +GIM) theory to the complete 3 generations.

You're statement is the basis of the theory, yes.
 
Thanks alot,
