Resumen

Using an e+e- collision data sample with a total integrated luminosity of 3.19 fb-1 collected with the BESIII detector at a center-of-mass energy of 4.178 GeV, the branching fraction of the inclusive decay of the Ds+ meson to final states including at least three charged pions is measured for the first time to be B(Ds+→π+π+π-X)=(32.81±0.35stat±0.63syst)%. In this measurement the charged pions from KS0 meson decays are excluded. The partial branching fractions of Ds+→π+π+π-X are also measured as a function of the π+π+π- invariant mass.
