Wolfgang Gradl (for the BABAR collaboration)
TL;DR
This paper reports preliminary measurements of cross sections for specific e+e- collision processes involving KS KL pi0 and KS KL pi0 pi0, using Initial State Radiation data from the BABAR experiment, including resonance substructure analysis.
Contribution
It provides new cross section measurements and resonance decay branching fractions for these processes, expanding understanding of charmonium decays.
Findings
Measured cross sections for e+e- --> KS KL pi0 and KS KL pi0 pi0.
Investigated the resonant substructure of KS KL pi0.
Determined branching fractions for J/psi and psi(2S) decays into these states.
Abstract
We present preliminary measurements of the cross sections for e+e- --> KS KL pi0 and KS KL pi0 pi0 obtained using the technique of Initial State Radiation with 469 fb^-1 of e+e- collision data collected with the BABAR detector at or near the Upsilon(4S) resonance. The resonant substructure of KS KL pi0 is investigated, and branching fractions for the decays of the charmonium resonances J/psi and psi(2S) into these final states are measured.
