| contents | Yang-Mills effective action from QCD at finite chemical potential C. Villavicencio E. S. Fraga Física, Astronomía y Matemáticas Mills action Effective Yang Perturbative QCD Finite chemical potential We present a construction of an effective Yang-Mills action for QCD, from the expansion of the fermionic determinant in terms of powers of the chemical potential at high temperature for the case of massless quarks. We analyze this expansion in the perturbative region and find that it gives extra spurious information. We propose for the non-perturbative sector a simplified effective action which, in principle, contains only the relevant information. 2007 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46413544009 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.1 Vol.37 |
