====== TTP12-013 Quantum Chromodynamics ====== The classical Lagrangian of chromodynamics, its quantization in the perturbation theory framework, and renormalization form the subject of these lectures. Symmetries of the theory are discussed. The dependence of the coupling constant \alpha_s on the renormalization scale \mu is considered in detail. |**A.G.Grozin** | |** Baikal summer school 2011 ** | | {{preprints:2012:ttp12-013.pdf|PDF}} {{preprints:2012:ttp12-013.ps|PostScript}} [[http://arxiv.org/abs/1205.1815|arXiv]] | | |
