Gribov Confinement and Chiral Perturbation Theory
I discuss the chiral dynamics of Gribov’s theory of confinement. At a critical coupling α s the light quark vacuum undergoes a series of phase transitions which should be taken into account in the application of chiral perturbation theory. The Gribov theory offers a simple explanation of the value of the pion nucleon sigma term without need to invoke a large strange quark component in the nucleon.
متن کاملColor Confinement in Perturbation Theory from a Topological Model
Color confinement by the mechanism of Kugo and Ojima can treat confinement of any quantized color carrying fields including dynamical quarks. However, the non-perturbative condition for this confinement has been known to be satisfied only in the pure-gauge model (PGM), which is a topological model without physical degrees of freedom. Here we analyze the Yang-Mills theory by adding physical degr...
متن کاملPerturbation Theory with Instantons
The large k asymptotics (perturbation series) for integrals of the form ∫ F μe ikS , where μ is a smooth top form and S is a smooth function on a manifold F , both of which are invariant under the action of a symmetry group G, may be computed using the stationary phase approximation. This perturbation series can be expressed as the integral of a top form on the space M of critical points of S m...
متن کاملStaggered Chiral Perturbation Theory for All-Staggered Heavy-Light Mesons
In HISQ simulations by the MILC and Fermilab Lattice collaborations, both the light quarks and the charm quark are staggered. We extend staggered chiral perturbation theory (S χ PT) to include such all-staggered heavy-light mesons. We assume that the heavy quark action is sufficiently improved that we may take am Q << 1 (where m Q is the heavy quark mass), but also that m Q >> Λ QCD so that a c...
متن کاملChiral Perturbation Theory for All-Staggered Heavy-Light Mesons
In highly improved staggered quark (HISQ) simulations by the HPQCD, MILC, and Fermilab Lattice collaborations, both the light quarks and the charm quark are staggered. We extend chiral perturbation theory for staggered quarks to include such all-staggered heavy-light mesons. We assume that the heavy quark action is sufficiently improved that we may take amQ << 1 (where mQ is the heavy quark mas...
