Measuring the a0-a2 pion scattering lengths through $K \to 3 \pi$ decays / Scimemi, Ignazio (Valencia U., IFIC) ; Gamiz, Elvira (Illinois U., Urbana) ; Prades, Joaquim (CERN)
We discuss the recent Cabibbo's proposal to measure the pion-pion scattering lengths combination a0-a2 from the cusp effect in the pi0-pi0 energy spectrum at threshold for K+ to (pi0 pi0 pi+) and KL to (pi0 pi0 pi0). We estimate the theoretical uncertainty of the a0-a2 determination at NLO in our approach and obtain that it is not smaller than 5% for K+ to (pi0 pi0 pi+). [...]

Determination of the $a_{0}-a_{2}$ pion scattering length from $K^{+} \to \pi^{+}\pi^{0}\pi^{0}$ decay / Cabibbo, Nicola (CERN)
We present a new method for the determination of the pion-pion scattering lenght combination a0-a2, based on the study of the pi0-pi0 spectrum in K->pi+ pi0 pi0 in the vicinity of the pi+ pi- threshold. The method requires a minimum of theoretical input, and is potentially very accurate..

Pion-pion scattering and the $K \to 3\pi$ decay amplitudes / Cabibbo, Nicola (CERN ; Rome U. ; INFN, Rome) ; Isidori, Gino (Frascati)
We revisit the recently proposed method for the determination of the pi-pi scattering length combination a_{0}-a_{2}, based on the study of the pi0 pi0 spectrum in K+ -> pi+ pi0 pi0. In view of a precision measurement, we discuss here the effects due to smaller absorptive contributions to the K+ -> pi+ pi0 pi0 and K+ -> pi+ pi+ pi- amplitudes. [...]
