Analysis
Instructions for the analysis
Theory predicts that the various processes should have the following proportions in the production of W particles:
| process | Feynman diagram | proportion |
|---|---|---|
| gluon quark interaction |   |
66% |
| gluon gluon interaction |   |
34% |
- Calculate using the measurement of R± how many times more W+ than W- particles were produced in
quark gluon interactions.
Hint 1: W+ and W- particles are produced at about the same rate in gluon gluon interaction.
Hint 2: 66% of all W particles are produced in quark gluon interactions whereas 34% of them are produced in gluon gluon interactions.
- What do you conclude from your result about the structure of the proton?
