Gluon Evolution and Saturation Proceedings

Understand

Almost 40 years ago, Gribov and colleagues at the Leningrad Nuclear Physics Institute developed the ideas that led to the Dokhsitzer-Gribov-Altarelli-Parisi the Baltisky-Fadin-Kuraev-Lipatov equations.

• These equations describe the evolution of the distributions for quarks and gluon inside a hadron to increased resolution scale of a probe or to smaller values of the fractional momentum of a hadronic constituent.
• I motivate and discuss the generalization required of these equations needed for high energy processes when the density of constituents is large.
• This leads to a theory of saturation realized by the Color Glass Condensate
