Silva Física, Astronomía y Matemáticas Lattice QCD Confinement Landau gauge Gluon propagator Ghost propagator We report on the infrared limit of the quenched lattice Landau gauge gluon propagator computed from largeasymmetric lattices. In particular, the compatibility of the pure power law infrared solution (q2)2k of the Dyson-Schwinger equations is investigated and the exponent k is measured. The lattice data favours k » 0:52, whichwould imply a vanishing zero momentum gluon propagator as predicted by the Kugo-Ojima confinement mechanismand the Zwanziger horizon condition. Results for the ghost propagator and for the running couplingconstant are shown. 2007 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46437207 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.1B Vol.37 |
