Cross-sections of backward proton production in 40-GeV/c pi- (K-, anti-p) A interactions

Antipov, Yu.M. ; Batarin, V.A. ; Bezzubov, V.A. ; et al.
Nucl.Phys.A 536 (1992) 637-647, 1992.
Inspire Record 337176 DOI 10.17182/hepdata.36704

The inclusive cross sections of backward proton production in π − ( K − , p ) -Be, Al, Cu, Pb interactions at 40 GeV/ c are presented. Protons have been detected in the angular range 150°–165° and kinetic energy region 0.1–0.3 GeV. The invariant cross-section ratios for various beam particles are independent of the values of kinetic energy and of the nuclear target type: 〈ƒ K − /ƒ π − 〉= 0.87 ± 0.03 stat ± 0.03 syst , 〈ƒ p /ƒ π − 〉 = 1.82 ± 0.10 stat ± 0.05 syst . The A -dependence of the cross-section slope parameter for A ⩾27 is less than ∼2%.

A STUDY OF FOUR AND SIX BODY REACTIONS IN K+ p AND pi+ p INTERACTIONS AT 250-GeV/c

The EHS/NA22 collaboration Ajinenko, I.V. ; Belokopytov, Yu. A. ; Bialkowska, H. ; et al.
Z.Phys.C 43 (1989) 15, 1989.
Inspire Record 279065 DOI 10.17182/hepdata.15471

Data on the reactions (K+/π+)p→(K+/π+)pπ+π- and (K+/π+)p→(K+/π+)p2π+2π-, obtained with the European Hybrid Spectrometer, are presented and compared with data at lower energies. The contribution of beam and target diffractive dissociation and double Pomeron exchange, and porperties of these reactions are discussed.

MEASUREMENT OF n p ELASTIC SCATTERING AT HIGH-ENERGIES AND VERY SMALL MOMENTUM TRANSFERS

The Freiburg-Moscow collaboration Arefev, A. ; Babaev, A. ; Bamberger, A. ; et al.
Nucl.Phys.B 232 (1984) 365, 1984.
Inspire Record 190837 DOI 10.17182/hepdata.33883

The np elastic differential cross section has been measured for incident neutron momenta 100–400 GeV/ c in the | t | range 6 · 10 −6 − 5 · 10 −1 (GeV/ c ) 2 . The np data of this experiment provide a first direct measurement of the hadronic amplitude for | t | < 10 −2 (GeV/ c ) 2 , which is consistent with the extrapolations from higher | t | values. Our data for | t | < 10 −4 (GeV/ c ) 2 are consistent with a rise which can be attributed to Schwinger scattering, caused by the interaction of the neutron magnetic moment with the proton.

Boson States in the Reaction pi- p --> pi- pi- pi+ p with Leading pi+ Meson at 25-GeV/c

The Serpukhov-CERN collaboration Antipov, Yu.M. ; Busnello, R. ; Damgaard, G. ; et al.
Nucl.Phys.B 119 (1977) 45-59, 1977.
Inspire Record 109772 DOI 10.17182/hepdata.35516

The reaction π − + p → π − + π − + π + + p at 25 GeV/ c was studied in the mass region M 3 π ⩾ 1.8 GeV with leading π + . The mass spectrum of the π + π − system shows peaks corresponding to the ϱ 0 , f and g 0 resonances and an enhancement around 1.9 GeV. Evidence is presented for a J P = 3 + s-wave g 0 π − state (A 4 ) similar to the ϱ 0 π − (A 1 ) and fπ − (A 3 ) threshold enhancements.

Nucl.Phys.B 86 (1975) 381-402, 1975.
Inspire Record 90643 DOI 10.17182/hepdata.32087

The reaction K − p → K − π − π + p has been measured at 25 and 40 GeV/ c at the Serpukhov Proton Accelerator. The production cross section at 25 and 40 GeV/ c as a function of momentum transfer and K ππ mass is presented, and results of the partial-wave analysis of the K ππ system yielding information about Q(1300), K ∗ (1400) and L(1770) mesons are discussed.
