Isospin Breaking Corrections to Low - Energy π − K Scattering
We evaluate the matrix elements for the processes π 0 K 0 → π 0 K 0 and π − K + → π 0 K 0 in the presence of isospin breaking terms at leading and next-to-leading order. As a direct application the relevant combination of the S-wave scattering lengths involved in the pion-kaon atom lifetime is determined. We discuss the sensitivity of the results with respect to the input parameters.
متن کاملThe Low Energy π π Amplitude To One and Two Loops
The low-energy ππ amplitude is computed explicitly to two-loop accuracy in the chiral expansion. It depends only on six independent (combinations of) low-energy constants which are not fixed by chiral symmetry. Four of these constants are determined via sum rules which are evaluated using ππ scattering data at higher energies. Dependence of the low-energy phase shifts and of the threshold param...
متن کاملFrom low-energy moments of Π(q2) to R(s)
We construct approximate formulas for the O(α3 s ) QCD contributions to the vector current correlator, which is valid for arbitrary values of momenta and masses. The derivation is based on conformal mapping and the Padé approximation procedure and incorporates known expansions in the low energy, threshold and high energy regions. We use our results to estimate additional terms in these expansions.

Electromagnetic corrections to the low-energy π+π− → π0π0 scattering amplitude at next-to-leading order in the chiral expansion are reviewed. Their effects on the corresponding scattering lengths are estimated and compared to the two-loop strong interaction contributions. Key-Words: Chiral perturbation theory, Pion, Electromagnetic corrections. Contribution to the Eighth International Symposium...
