چکیده
We determine the kinetic coefficients of ultrasoft pions using chiral perturbation theory at finite temperature close to limit. This is used compute axial charge diffusion and damping in hydrodynamic effective for these pion waves. show that provide a leading order answer one needs explore dynamics hard, soft, modes, which are represented microscopically by appropriate descriptions..

Off-shell electromagnetic form factors of pions and kaons in chiral perturbation theory.
The off–shell electromagnetic vertex of a (pseudo–) scalar particle contains, in general, two form factors F and G which depend, in addition to the squared momentum transfer, on the invariant masses associated with the initial and final legs of the vertex. Chiral perturbation theory to one loop is used to calculate the off–shell form factors of pions and kaons. The formalism of Gasser and Leutw...
متن کاملLow – energy photon – photon fusion into three pions in Generalized Chiral Perturbation Theory ∗
The processes γγ → π0π0π0 and γγ → π+π−π0 are considered in Generalized Chiral Perturbation theory, in view of their potential sensitivity to the mechanism of spontaneous breaking of chiral symmetry and to various counterterms. The amplitudes are computed up to order O(p6). The event production rates are estimated for the Daphne φ–Factory and for a future τ–Charm Factory. ∗Work supported in par...

BES II data for J/Ψ → K * (890)Kπ reveal a strong κ peak in the Kπ S-wave near threshold. Both magnitude and phase are determined in slices of Kπ mass by interferences with strong K 0 (1430), K 1 (1270) and K 1 (1400) signals. The phase variation with mass agrees within errors with LASS data for Kπ elastic scattering. A combined fit is presented to both BES and LASS data. The fit uses a Breit-W...

Abstract. The charged kaon decay channel K l3γ allows for studies of direct CP violation, possibly due to non-standard mechanisms, with the help of T -odd correlation variables. In order to be able to extract a CP -violating signal from experiment, it is necessary to understand all possible Standard Model phases that also produce T -odd asymmetries. We complement earlier studies by considering ...
متن کاملApplied Chiral Perturbation Theory
I consider some selected topics in chiral perturbation theory (CHPT) as probed at colliders such as DAΦNE. Emphasis is put on processes involving pions in the isospin zero S-wave which require multi-loop calculations. These include the scalar form factor of the pion, two–photon fusion into pion pairs and Kl4–decays. The physics of the chiral anomaly is briefly touched upon INVITED LECTURE SUMME...
