dc.description.abstractUsing 16 energy points of e(+) e(-) annihilation data collected in the vicinity of the J/Psi resonance with the BESIII detector and with a total integrated luminosity of around 100 pb(-1), we study the relative phase between the strong and electromagnetic amplitudes of J/Psi decays. The relative phase between J/Psi electromagnetic decay and the continuum process (e(+) e(-) annihilation without the J/Psi resonance) is confirmed to be zero by studying the cross section lineshape of mu(+) mu(-) production. The relative phase between J/Psi strong and electromagnetic decays is then measured to be (84.9 +/- 3.6)degrees or (-84.7 +/- 3.1)degrees for the 2(pi(+) pi(-) )pi(0) final state by investigating the interference pattern between the J/Psi decay and the continuum process. This is the first measurement of the relative phase between J/Psi strong and electromagnetic decays into a multihadron final state using the lineshape of the production cross section. We also study the production lineshape of the multihadron final state eta pi(+) pi(-) with eta -> pi(+) pi(-) pi(0) , which provides additional information about the phase between the J/Psi electromagnetic decay amplitude and the continuum process. Additionally, the branching fraction of J/Psi -> 2(pi(+) pi(-) )pi(0) is measured to be (4.73 +/- 0.44)% or (4.85 +/- 0.45)%, and the branching fraction of J/Psi -> eta pi(+) pi(-) is measured to be (3.78 +/- 0.68) x 10(-4). Both of them are consistent with the world average values. The quoted uncertainties include both statistical and systematic uncertainties, which are mainly caused by the low statistics.
