In this talk, I will discuss high-energy hadronic collisions involving moderate momentum transfers. Such reactions are the realm of multiple scatterings and gluon saturation, and cannot be handled by the usual approaches. I will expose a framework - the Colour Glass Condensate - in which one can compute observables related to such collisions; and explain how, at leading order, the problem reduces to finding classical solutions of the Yang-Mills equations. I'll also briefly discuss some ongoing work that aims at studying loop corrections and factorization in this framework.
