π±p elastic differential cross sections in the momentum range 1.72-2.80 GeV/c have been measured at the proton synchrotron "NIMROD" of the Rutherford High Energy Laboratory. The results are tabulated, and analyses of the differential cross sections employing optical models and Legendre polynomial expansions are advanced. A critical discussion of a recent interpretation of differential-cross-section structure in terms of interference between resonant and background amplitudes is presented.

Study of the process $e^+⁢e^-\to \pi^+\pi^-\pi^0$ in the energy range 840-1020 MeV on the VEPP-2M storage ring with the Cryogenic Magnetic Detector

On the electron-positron storage ring VEPP-2M using the Cryogenic Magnetic Detector, the cross section of the e+e- -> π+π-⁢π0 process was measured in the energy range 2x420-2x510 MeV. The energy dependence of the cross section is consistent with the predictions of the vector dominance model taking into account the interference of omega and phi mesons. The optimal value of the omega-phi interference phase is 136+-36+-10 degree.
