Quenched Finite Volume Logarithms
Quenched chiral perturbation theory is used to compute the first finite volume correction to the quenched chiral condensate. The correction diverges logarithmically with the four-volume V . We point out that with dynamical quarks one can obtain both the chiral condensate and the pion decay constant from the distributions of the lowest Dirac operator eigenvalues. ∗On leave from: The Niels Bohr I...
متن کاملQuenched chiral logarithms.
I develop a diagrammatic method for calculating chiral logarithms in the quenched approximation. While not rigorous, the method is based on physically reasonable assumptions, which can be tested by numerical simulations. The main results are that, at leading order in the chiral expansion, (a) there are no chiral logarithms in quenched fπ, for mu = md; (b) the chiral logarithms in BK and related...
متن کاملChiral logarithms in quenched QCD
2014 From a strong coupling investigation of quenched QCD, and an analysis of a previous numerical simulation of quenched SU(2), we show that the infrared logarithms expected in the chiral limit of complete QCD are not suppressed by the suppression of all internal quark loops. This result explains the apparent nonvanishing of 03C0-mass extrapolations at zero quark mass, previously observed in s...
متن کاملEnhanced chiral logarithms in partially quenched QCD
I discuss the properties of pions in “partially quenched” theories, i.e. those in which the valence and sea quark masses, mV and mS, are different. I point out that for lattice fermions which retain some chiral symmetry on the lattice, e.g. staggered fermions, the leading order prediction of the chiral expansion is that the mass of the pion depends only on mV , and is independent of mS . This s...
متن کاملFinite-Volume Scaling of the Quenched Chiral Condensate∗
Surprisingly, there exists a deep connection between finite-volume gauge theories with spontaneous breaking of chiral symmetries, and Random Matrix Theory (RMT). In the chiral limit mi → 0 such that μi ≡ miΣV are kept fixed, the field-theoretic partition functions Zν({μi}) become identical to certain (chiral) RMT partition functions [1]. Here Σ denotes the (conventional) infinite-volume chiral ...
