| contents | Saturation in High-energy QCD Grégory Soyez Física, Astronomía y Matemáticas High energy QCD Saturation Geometric scaling In these proceedings, I shall review the basic concepts of perturbative QCD in its high-energy limit, emphasisingthe approach to the unitarity limit, usually referred to as saturation. I shall explain the basic frameworkshowing the need for saturation, first, from a simple picture of the high-energy behaviour, then, giving a shortderivation of the equation driving this evolution. In the second part, I shall exhibit an analogy with statisticalphysics and show how this allows to derive geometric scaling in QCD with saturation. I shall finally considerthe effects of gluon-number fluctuations on this picture. 2006 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46436613 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.4A Vol.36 |
