Comparison of Exclusive Reactions at Large $T$

Baller, B.R. ; Blazey, G.C. ; Courant, H. ; et al.
Phys.Rev.Lett. 60 (1988) 1118-1121, 1988.
Inspire Record 264273 DOI 10.17182/hepdata.3063

Cross sections or upper limits are reported for 12 meson-baryon and two baryon-baryon reactions for an incident momentum of 9.9 GeV/c, near 90° c.m.: π±p→pπ±,pp±,π+°±,K+Σ±, (Λ0/Σ0)K0; K±p→pK±; p±p→pp. By studying the flavor dependence of the different reactions, we have been able to isolate the quark-interchange mechanism as dominant over gluon exchange and quark-antiquark annihilation.

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.

Phys.Lett.B 24 (1967) 596-598, 1967.
Inspire Record 1389623 DOI 10.17182/hepdata.29569

The differential elastic scattering cross section for 2.24 GeV/ c K − p collisions has been measured in film from the Brookhaven 20″ bubble chamber. The total elastic cross section is found to be 6.2 ± 0.7 mb. The exponential dependence on square of the momentum t in (GeV/ c ) 2 is fitted by ( d σ d Ω elastic = (12.4 ± 1.0 mb/sr) exp (7.81 ± 0.25)t . A A fit to a black disc model requires a radius of 0.95 ± 0.05 fm.

Study of k- pi- scattering using the reaction k- d ---> k- pi- p p(s)

Cho, Y. ; Derrick, M. ; Johnson, D. ; et al.
Phys.Lett.B 32 (1970) 409-412, 1970.
Inspire Record 63111 DOI 10.17182/hepdata.28719

Approximately 700 events of the reaction K − d → K − π − pp s produced by 5.5 GeV/ c kaons were used to measure the cross section for Kπ elastic scattering in the T = 3 2 state by a Chew-Low extrapolation. The cross section does not exceed 2.1 mb and has no structure for Kπ masses from threshold up to 2.0 GeV.

STUDY OF THE I = 3/2 K- pi- ELASTIC SCATTERING FROM THE REACTION K- p ---> K- pi- p pi+ AT 4.25-GeV/c INCIDENT K- MOMENTUM

Jongejans, B. ; van Meurs, R.A. ; Tenner, A.G. ; et al.
Nucl.Phys.B 67 (1973) 381-394, 1973.
Inspire Record 80765 DOI 10.17182/hepdata.32357

Results on the elastic K − π − scattering have been obtained from a study of the K − π − system in 15 000 events of the type K − p→K − π − p π + at a K − beam momentum of 4.25 GeV/ c . The on-mass-shell values of the spherical harmonic moments of the K − π − scattering angular distribution and the K − π − elastic cross section have been obtained by extrapolation to the pion pole. From these values we determined the s- and p-wave phase shifts δ 0 3 and δ 1 3 as a function of the effective mass of the K − π − system between threshold and 1.25 GeV/ c 2 . The value of | δ 0 3 | is smaller than 17° for all mass values and the existence of a p-wave cannot be neglected. At m K − π − = 1.18 GeV/ c 2 there are two solutions for the phase shifts. On the average, the cross section of the K − π − elastic scattering over the region of the effective mass considered amounts to approximately 2.5 mb.

We present preliminary results on the measurement of a variety of exclusive hadron interactions at center of mass scattering angles of 90°. Data are also presented which show the relative transparency of nuclei to πp and pp elastic scattering in this kinematic range.

K+- p elastic scattering at 5 gev/c. evidence for a k- p backward peak

Chabaud, V. ; Eide, A. ; Lehmann, P. ; et al.
Phys.Lett.B 38 (1972) 445-448, 1972.
Inspire Record 75816 DOI 10.17182/hepdata.5729

The elastic scattering of K ± mesons on protons has been studied at 5 GeV/c. A total of about 500 000 events have been measured in the c.m. angular range 17° < θ cm < 165° corresponding to 0.2 < − t < (GeV/ c ) 2 . We observed a K − p backward peak which we have parametrized as d σ /d u = (0.6 ± 0.2) exp [(3.3 ± 0.6) u ] μb /(GeV/c) 2 , while for the K + p backward peak we find d σ /d u = (17.5 ± 1) exp [(3.6 ± 0.2) u ] μb /(GeV/c) 2 . The K − p cross-section falls to about 0.03 μ b ( GeV /c) 2 around − t = 5 (GeV/ c ) 2 , while the K + p cross-section stays in the vicinity of 0.3 μ b ( GeV /c) 2 in the same t -region. The K + p and K − p differential cross-sections have cross-over points at − t = 0.2, 1.1 and about 3.5 (GeV/ c ) 2 .
