Fraga Física, Astronomía y Matemáticas Finite Yukawa theory Equation of state temperature field theory Recent results for the two-loop thermodynamic potential of QCD at finite density have shown that nonzeroquark mass corrections to the pressure are relevant and can dramatically affect the structure of compact stars.Motivated by these findings, we consider a simple toy model cold and dense Yukawa theory to study theeffects of finite fermion masses on the pressure. The role of renormalization group running of the coupling andmass is also discussed. Results within this simple model might be useful in the description of condensates inthe core of neutron stars. 2007 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46437110 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.1A Vol.37 |
