We present the results on total channel cross-sections obtained in the Saclay 180 l HBC exposed to a separated K− beam at Nimrod. The cross-sections for each channel are given at 13 incident K− momenta between 1.26 and 1.84 GeV/c.

Inspire Record 75745 DOI 10.17182/hepdata.41300

The K ∗− spectrum in the reaction K − +p → K ∗− +p has been measured at beam momenta 10.9, 13.4 and 15.9 GeV/ c using the missing mass technique. Production of the L(1770), and a Q-K ∗ (1420) enhancement are observed. Differential cross sections in the range of momentum transfer 0.12 < | t pp | < 0.40 (GeV/ c ) 2 are given. The L meson is observed with a width Γ = 100 ± 26 MeV. The mass spectrum between the L and 2.5 GeV does not show significant structure.

Reaction pi+ p ---> rho+ p at 2.67 gev/c - a study of isoscalar exchanges

Michael, W. ; Gidal, G. ;
Phys.Rev.Lett. 28 (1972) 1475-1479, 1972.
Inspire Record 75483 DOI 10.17182/hepdata.21443

Results are presented of a study of the reaction π+p→ρ+p at 2.67 GeV/c incident π+ momentum. The contributions due to given spin-parity exchanges are isolated; and, by combining these results with those of a similar π− experiment, the It=0 component of each series is separated. The ω (I=0, JPG=1−−) exchange contribution shows a pronounced dip at −t=0.4 (GeV/c)2. Evidence is presented for the exchange of a state of minimum quantum numbers, H (I=0, JPG=1+−).

Elastic electron - Proton Scattering at Large Four Momentum Transfer

Kirk, Paul N. ; Breidenbach, Martin ; Friedman, Jerome I. ; et al.
Phys.Rev.D 8 (1973) 63-91, 1973.
Inspire Record 73424 DOI 10.17182/hepdata.21999

Electron-proton elastic-scattering cross sections have been measured at the Stanford Linear Accelerator Center for four-momentum transfers squared q 2 from 1.0 to 25.0 (GeVc)2. The electric (GEp) and magnetic (GMp) form factors of the proton were not separated, since angular distributions were not measured at each q 2. However, values for GMp were derived assuming various relations between GEp and GMp. Several theoretical models for the behavior of the proton magnetic form factor at high values of q 2 are compared with the data.

Search for narrow resonances in the r region

Bowen, D. ; Earles, D. ; Faissler, W. ; et al.
Phys.Rev.Lett. 29 (1972) 890-893, 1972.
Inspire Record 75434 DOI 10.17182/hepdata.21418

We report on a measurement of the missing-mass, (mm)−, spectrum from the reaction π−+p→(mm)−+p at 8 GeV. The data contain 6500 events in the R peak (M2=2.72±0.02 GeV2, Γ=139±31 MeV). The R shape is consistent with either a single Breit-Wigner or several wide resonances, as suggested by bubble-chamber experiments, but inconsistent with the series of narrow resonances reported by the CERN missing-mass group.
