 The use of QCD evolution to detect gluon saturation in exclusive photo-production of vector mesons / Hentschinski, Martin (Americas U., Puebla) We investigate photo-production of vector mesons J/Ψ and Υ measured both at HERAand LHC, using 2 particular fits of inclusive unintegrated gluon distributions.The fits are based on non-linear Balitsky-Kovchegov evolution (Kutak-Sapetagluon; KS) and next-to-leading order Balitsky-Fadin-Kuraev-Lipatov evolution(Hentschinski-Sabio Vera-Salas gluon; HSS).
