Problems with the quenched approximation in the chiral limit [electronic resource]
In the quenched approximation, loops of the light singlet meson (the η′) give rise to a type of chiral logarithm absent in full QCD. These logarithms are singular in the chiral limit, throwing doubt upon the utility of the quenched approximation. In previous work, I summed a class of diagrams, leadi...
