Differential cross sections for elastic (π+p) and π−p) scattering between 400 MeV/c and 590 MeV/c

Phase-shift analysis of ?+ p-scattering in the energy region from 194 to 600 MeV

“…The use of precise data on a(O) and P(O) obtained at LNPI [1,2] ~S,GeV 560 MeV which is in agreement with the predictions of the PSA [21,24]. At energies lower than 350MeV a quantitative agreement is observed with the PSA solution [6] for 7r+p scattering (Fig.…”

“…The results of the LNPI PSA are compared in Figs. 1 and 2 with the results of the latest phase-shift analyzes [6,21,24] that do not utilize the data on P(O) obtained in LNPI [2,3]. The inverse solutions of the LNPI PSA are assigned asterisks.…”

“…The procedures for interpolation of cross sections and polarizations as well as for excluding unreliable experimental points were performed automatically on the basis of the LNPI bank of data on nN scattering. In the PSA we made use of all the data on a(O) and P(O) obtained in LNPI [1,2] as well as of the results published in [11][12][13][14][15][16][17][18][19]. In Ref.…”

“…Within the framework of this program at the LNPI the measurements of the differential cross sections a+(O) [-1] and of the polarization parameters P_+(O) [2,3] in ~-+p scattering have been carried out. Before the investigations were initiated, and during accumulation of experimental data at the LNPI, phase-shift analyses (PSA) of ~N scattering were performed [-4, 5].…”

Delta excitation in antiproton-deuteron annihilation

“…system. The squares show the results for s = 1.251 GeV 2 [21], the triangles for 1.474 [22] and the circles for 1.711 [23] . The solid, dashed and dotted lines show our results calculated with the resonance model.…”
