For a few months the LHC is gathering data of its first p-Pb run. This is the first time that we expect to clearly probe dense QCD matter. Saturated media in QCD seem to be properly described by the CGC effective field theory. On this basis we worked out the di-gluon production inclusive cross-section which is the dominant process at the LHC and the simplest evidence of saturation through the so called decoherence effect. My aim is first to give a detalled explanation of the importance for studying the di-gluon production at the LHC. Then I sketch the computation and emphasize the meaning of the structure of the cross-section. At the end I push up the strongly correlated regime in which analytic calculations can be easily continued. \ \ This work is in collaboration with Edmond Iancu.
