# Quark parton model

• A
Hi,

I've been studying the quark parton model recently and all seems fine at first. However, there's just one thing bugging me right now. So in the quark parton model it is assumed that inelastic lepton-hadron scattering can be explained by elastic lepton-hadron scattering, but how can it be? I've seen articles saying something like an incoherent sum of elastic scatterings and I suppose that's the answer, but I just don't get it how is it possible to sum a load of elastic scatterings into something inelastic? if each of them does not lose energy then why does the sum of them lose energy?

Might be a silly question but just bear with me please. Thanks.

If you scatter elastic from a parton then you give energy to this parton - if it gets enough energy this will lead to the creation of new particles from the hadron it was part of.
