Finite volume effects in chiral perturbation theory
There has recently been an intense activity in the study of finite volume effects by means of chiral perturbation theory. In this contribution I review recent work in this field both for the ǫ– (MπL . 1) and the p–regime (MπL ≫ 1). For the latter I emphasize the importance of going beyond leading order calculations in chiral perturbation theory and the usefulness of asymptotic formulae à la Lüs...
متن کاملFinite-volume meson propagators in quenched chiral perturbation theory
Recent progress in the formulation of chiral fermions on the lattice makes it possible to approach the regime of the physical light quark masses. However, lattice volumes V = L needed to ensure negligible finite size effects are prohibitively large for such light quarks. Only when L is very large compared to the Compton wavelength of the lightest particles of the theory (i.e. the pions) are the...
متن کاملform factor at order p 6 of chiral perturbation theory
K 0 form factor at order p 6 of chiral perturbation theory Abstract This paper describes the calculation of the electromagnetic form factor of the K 0 meson at order p 6 of chiral perturbation theory which is the next-to-leading order correction to the well-known p 4 result achieved by Gasser and Leutwyler. On the one hand, at order p 6 the chiral expansion contains 1-and 2-loop diagrams which ...
متن کاملPion form factor analysis using NLO analytic perturbation theory
I present results for the pion’s electromagnetic form factor in the spacelike region, which implement the most advanced perturbative information currently available for this observable in conjunction with a pion distribution amplitude that agrees with the CLEO data on the pion-photon transition form factor at the 1σ level. I show that using for the running strong coupling and its powers their a...
متن کاملNear-threshold Isospin Violation in the Pion Form Factor from Chiral Perturbation Theory
We examine the isospin violation in the timelike pion form factor near threshold at next-to-leading order in the chiral expansion using the techniques of Chiral Perturbation Theory. This next-to-leading order contribution contains the first nonvanishing isospin violation. This isospin violation is found to be very small near threshold. In particular, the isospin violation at threshold is found ...
