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%

  1. 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.

  2. What do you conclude from your result about the structure of the proton?
