“…Future calculations should test the elasticity assumption by computing correlators using operators that resemble four pions projected into isospin-2 in the appropriate partial waves. e. Results: In Figure 3 we show our results for S and D-wave phase shifts, at a range of pion masses, along with experimental data taken from [8][9][10][11]. We observe reasonable agreement with the experimental data at lower scattering momenta, where the scattering is purely elastic, for all the pion masses computed.…”

Recent progress at understanding the excited state spectra of mesons and baryons is described. I begin by outlining the application of the variational method to compute the spectrum of QCD, and then present results for the excited meson spectrum, with continuum quantum numbers of the states clearly delineated. I emphasise the need to extend the calculation to encompass multihadron contributions, and describe a recent calculation of the I = 2 ππ energy-dependent phase shifts as a precursor to the study of channels with resonant behavior. I conclude with recent results for the low lying baryon spectrum, and the prospects for future calculations.

Using 281 pb −1 of data recorded by the CLEO-c detector in e + e − collisions at the ψ(3770), corresponding to 0.78 million D + D − pairs, we investigate the substructure of the decay D + → π − π + π + using the Dalitz plot technique. We find that our data are consistent with the following intermediate states: ρ(770)π + , f 2 (1270)π + , f 0 (1370)π + , f 0 (1500)π + , f 0 (980)π + , and σπ + . We confirm large S wave contributions at low ππ mass. We set upper limits on contributions of other possible intermediate states. We consider three models of the ππ S wave and find that all of them adequately describe our data.
