$K^- + p$ elastic scattering at 3.46 GeV/c

Gordon, J. ;

Phys.Lett. 21 (1966) 117-120, 1966.

Inspire Record 1389617 DOI 10.17182/hepdata.29930

1691 events were fitted to K - p elastic scatters at a K - momentum of 3.46 GeV/ c . The differential cross section as a function of 4 momentum transfer was fitted to exp ( A + Bt + Ct 2 ) with A = 3.7 B = 8.7 ( GeV / c ) −2 and C = 2.0 ( GeV / c ) −4 . The distribution is consistent with zero real part for the forward scattering amplitude.

Observation of the reaction $d + d \to ^{4}He + 2\pi$ at 1.69 GeV/c

Chapman, K.R. ; Jafar, J.D. ; Martelli, G. ; et al.

Phys.Lett. 21 (1966) 465-467, 1966.

Inspire Record 1389641 DOI 10.17182/hepdata.29926

The momentum spectrum of 4 He produced at 0 o lab. by deuteron collisions at 1.69 GeV/ c , has been measured to determine possible π-π resonances of low effective mass values. No significant deviations from phase space are found. The total cross sections for the reaction d + d → 4 He + 2π is found to be (0.6±0.2) × × 10 −30 cm 2 .

Search for new meson resonances in $K^+ p$ interactions at 12.7 GeV/c

Berlinghieri, J.C. ; Farber, M.S. ; Ferbel, T. ; et al.

Phys.Lett.B 27 (1968) 665-668, 1968.

Inspire Record 1389653 DOI 10.17182/hepdata.29197

In a study of K + p interactions at 12.7 GeV/ c we have carried out a search for meson resonances having any one of the following properties: (a) a strangeness of S =2, (b) S =1 and isotopic spin of I= 3 2 , or (c) S =1, I= 1 2 and decaying into an antihyperon ( Y ) and a nucleon (N).

Backward scattering of positrons and electrons on protons

Bouquet, B. ; Benaksas, D. ; Grossetête, B. ; et al.

Phys.Lett.B 26 (1968) 178-180, 1968.

Inspire Record 1389620 DOI 10.17182/hepdata.29320

The ratio R = σ (e + + p)/ σ (e − + p) of the elastic scattering cross-section detecting the recoil proton at 0 o in coincidence with the backward electron or positron was found to be R = 1.036 ± 0.018 at q 2 = 8 fm −2 , R = 1.079 ± 0.046 at q 2 = 32 fm −2 .

The angular distribution of backward elastically scattered pions at 3.55 GeV/c

Baker, W.F. ; Carlson, P.J. ; Chabaud, V. ; et al.

Phys.Lett. 23 (1966) 605-609, 1966.

Inspire Record 1389621 DOI 10.17182/hepdata.29776

The elastic scattering of 3.55 GeV/ c π + and π − mesons by protons was measured at centre-of-mass angles between 165° and 177°. The angular distributions for 864 events show a steeply rising backward peak for π + p, while the shape is less clear for π − p.
