A preliminary analysis of eta' -> eta pi pi in chiral theories
Preliminary results for the Dalitz plot distribution of
decays in the frameworks of Large- Chiral
Perturbation Theory and Resonance Chiral Theory are given. We hope our results
to be of some relevance for the present and forthcoming analysis of these
decays at GAMS, CLEO, VES, KLOE-2, Crystal Ball, Crystal Barrel, WASA, and
BES-III.Comment: 5 pages, uses aipproc style. Talk presented at the XIII International

Dispersive representation of the K pi vector form factor and fits to tau -> K pi nu(tau) and Ke3 data
Recently, we introduced several dispersive representations for the vector
form factor and fitted them to the Belle spectrum of . Here, we briefly present the model and discuss the results for the
slope and curvature of arising from the best fit. Furthermore, we
compare the pole position of the charged computed from our model
with other results in the literature. Finally, we discuss the prospects of a
simultaneous fit to and spectra.Comment: Talk given at "International Workshop on Effective Field Theories:
