The Mesonic Chiral Lagrangian of Order p 6 ∗
We construct the effective chiral Lagrangian for chiral perturbation theory in the mesonic even-intrinsic-parity sector at order p. The Lagrangian contains 112 in principle measurable + 3 contact terms for the general case of n light flavours, 91+3 for three and 53+4 for two flavours. The equivalence between equations of motion and field redefinitions to remove spurious terms in the Lagrangians...
متن کاملExtension of the chiral perturbation theory meson Lagrangian to order p6.
We have derived the most general chirally invariant Lagrangian L 6 for the meson sector at order p 6. The result provides an extension of the standard Gasser-Leutwyler Lagrangian L 4 to one higher order, including as well all the odd intrinsic parity terms in the Lagrangian. The most difficult part of the derivation was developing a systematic strategy so as to get all of the independent terms ...
متن کاملMesonic chiral rings in Calabi-Yau cones from field theory
We study the half-BPS mesonic chiral ring of the N = 1 superconformal quiver theories arising from N D3-branes stacked at Y pq and Labc Calabi-Yau conical singularities. We map each gauge invariant operator represented on the quiver as an irreducible loop adjoint at some node, to an invariant monomial, modulo relations, in the gauged linear sigma model describing the corresponding bulk geometry...
متن کاملAnomalous mesonic interactions near a chiral phase transition.
The axial anomaly is the observation that for fermions coupled to a gauge field, the divergence of the current for axial fermion number is not just the standard contribution from the classical equations of motion. In addition, at one loop order the divergence also contains a new term from quantum effects [1]. Due to deep geometrical reasons, there are no further corrections to this new term bey...
متن کاملStrange Mesonic Transition Form Factor in the Chiral Constituent Quark Model
The form factor g (S) ρπ (Q2) of the strange vector current transition matrix element 〈ρ|s̄γμs|π〉 is calculated within the chiral quark model. A strange vector current of the constituent U andD-quarks is induced by kaon radiative corrections and this mechanism yields the nonvanishing values of g (S) ρπ (0). The numerical result at the photon point is consistent with the one given by the φ-meson ...
