Quenched Chiral Perturbation Theory for Vector Mesons

We develop quenched chiral perturbation theory for vector mesons made of light quarks, in the limit where the vector meson masses are much larger than the pion mass. We use this theory to extract the leading nonanalytic dependence of the vector meson masses on the masses of the light quarks. By comparing with analogous quantities computed in ordinary chiral perturbation theory, we estimate the ...

Quenched and Partially Quenched Chiral Perturbation Theory for Vector and Tensor Mesons

Quenched and partially quenched chiral perturbation theory for vector mesons is developed and is used to extract chiral loop correction to the ρ meson mass. Connections to fully quenched and totally unquenched chiral perturbation theory results are discussed. It is also shown that (partially) quenched perturbation theory for tensor mesons can be formulated analogously, and the chiral correction...

Chiral perturbation theory for vector mesons.

The interactions of , K , and ! vector-mesons with low-momentum , K and pseudoscalar mesons are constrained by chiral symmetry. We derive a heavy vector-meson chiral Lagrangian in which the vector mesons are treated as heavy static matter elds. The unknown couplings of the chiral Lagrangian are further related using the 1=Nc expansion. Chiral perturbation theory is applied to the vector-meson m...

Quenched chiral perturbation theory for heavy-light mesons.

We formulate quenched chiral perturbation theory for heavy-light mesons coupled to pions, and calculate the one-loop chiral logarithmic corrections to fB, fBs , BB and BBs . We also calculate these corrections for “partially quenched” theories. In both theories, the chiral logarithms diverge in the chiral limit, indicating that (partially) quenched theories should not be used to study this limi...

Quenched Chiral Perturbation Theory

Partially quenched theories are theories in which the valenceand seaquark masses are different. In this paper we calculate the nonanalytic one-loop corrections of some physical quantities: the chiral condensate, weak decay constants, Goldstone boson masses, BK and the K + → π+π0 decay amplitude, using partially quenched chiral perturbation theory. Our results for weak decay constants and masses...
