# I need help interpreting form factor relations in parton model

Hello

My first post here and I don't know if this is the right place but i'm trying to get a grip on form factors when it comes to deep inelastic scattering. My tool is Gordon Kane's Modern Elementary Particle Physics. Exercises 5 and 6 chapter 18 seems like good exercises but I need som help in interpreting the meaning of the different relations

1. The problem statement, all variables and given/known data

The exercise states that one is to interpret three ralations regarding partons in deep inelastic scattering. Starting with $$\int^{1}_{0}{xdx\sum_{i=q, \bar{q}, g} f_i (x) = 1$$

where $$f_i (x)$$ is the probability of finding i:th parton with fractional momentum x

2. Relevant equations

My interpretation is that it simply states that the probability of finding any parton with any momentum is 1

Is this correct?
