Study of the reactions pi+ p ---> k+ sigma+ and pi+ p ---> k+ y*+(1385) between 3.5 and 14 gev/c

Measurements of the differential cross section for the reactions π+p→K+Σ+ and π+p→K+Y*+(1385) are reported at 3.5, 3.75, 4.0, 4.25, 4.5, 4.75, 5.0, 6.0, 10.0, and 14.0 GeV/c. Polarization in π+p→K+Σ+ is also reported at 6.0, 10.0, and 14.0 GeV/c. At small |t|, the cross section for π+p→K+Σ+ is well described by an exponential Aebt with slopes in the range b≈8−10 (GeV/c)−2; for |t|>0.5 (GeV/c)2 this slope decreases considerably. The cross section for π+p→K+Y*+(1385) is well described for |t|>0.2 (GeV/c)2 by a single exponential of slope about half that for π+p→K+Σ+; there is no break near |t|>0.5 (GeV/c)2. We observe a dip in this cross section near t=0. The polarization in π+p→K+Σ+ is consistent with zero for |t|<0.4 (GeV/c)2 and becomes large and positive for larger |t|.

PHOTOPRODUCTION OF pi0 FROM NEUTRONS AT 4-Gev

Bolon, G.C. ; Bellenger, D. ; Lobar, W. ; et al.
Phys.Rev.Lett. 27 (1971) 964, 1971.
Inspire Record 67576 DOI 10.17182/hepdata.29303

We have measured the reaction γ+n→π0+n at a photon energy of 4 GeV for 0.2<~−t<~1.8(GeVc)2. The cross section is slightly less than that with protons as a target.

DCS for π − p elastic scattering from 1.2 to 3.0 GeV/ c and phase shift analysis

Aplin, P.S. ; Cowan, I.M. ; Gibson, W.M. ; et al.
Nucl.Phys.B 32 (1971) 253-284, 1971.
Inspire Record 1104030 DOI 10.17182/hepdata.69638

Differential cross sections have been measured for π − p elastic scattering at laboratory momenta in the range 1.2 to 3.0 GeV/ c for the c.m. range 0.97 > cos θ ∗ > −0.98 . The corresponding mass range is 1.78 to 2.56 GeV/ c 2 . The data was obtained from a counter experiment in which the scattered pions and protons were detected in coincidence by arrays of scintillation counters.

MEASUREMENTS OF PI0 PHOTOPRODUCTION CROSS-SECTIONS FOR INCIDENT GAMMA-RAY ENERGIES OF 2.0-Gev/c TO 5.0-Gev/c

Bolon, G.C. ; Garelick, C. ; Homma, S. ; et al.
Phys.Rev.Lett. 18 (1967) 926, 1967.
Inspire Record 51286 DOI 10.17182/hepdata.21770

Cross sections for the reaction γ+p→π0+p for incident gamma-ray energies of 2.0 to 5.0 GeV and for baryon four-momentum transfers squared of 0.5 to 4.0 (GeV/c)2 are presented. The results are compared with theoretical predictions based on Reggeized vector-meson exchange.
