Observation of eta' -> pi(+) pi(-) pi(+) pi(-) and eta' -> pi(+) pi(-) pi(0) pi(0)

Physical Review Letters, 2014
Using a sample of 1.3 x 10(9) J/psi events collected with the BESIII detector, we report the first observation of eta' -> pi(+) pi(-) pi(+) pi(-) and eta' -> pi(+) pi(-) pi(0) pi(0). The measured branching fractions are B(eta' -> pi(+) pi(-) pi(+) pi(-)) = [8.53 +/- 0.69(stat.) +/- 0.64(syst.)] x 10(-5) and B(eta' -> pi(+) pi(-) pi(0) pi(0))

Study of the D°---> pi- pi+ pi- pi+ decay

2007
Using data from the FOCUS (E831) experiment at Fermilab, we present new measurements for the Cabibbo-suppressed decay mode $D^0 \to \pi^-\pi^+\pi^-\pi^+$. We measure the branching ratio $\Gamma(D^0 \to\pi^+\pi^- \pi^+\pi^-)/\Gamma(D^0 \to K^-\pi^+\pi^-\pi^+) = 0.0914 \pm 0.0018 \pm 0.0022$.

pi pi --> pi pi cross-sections near threshold

1998
An analysis of new data for the reaction p6p!p6p1n at incident energies between 223 and 284 MeV is presented. p1p2 cross sections are obtained via Goebel-Chew-Low techniques by extrapolation to the pion pole using the pseudoperipheral approximation. A consistency check between the present experimental results and previous experiments at higher energies
