The K/sup -/p charge exchange and elastic scattering reactions at 42 GeV/c / Marzano, F ; Blokzijl, R ; Gavillet, P ; Gay, J B ; Grossmann, P ; Heinen, P M ; Hemingway, R J ; Jongejans, B ; Kluyver, J C ; Maréchal, B et al.
Results are presented on the reactions K/sup -/p to K/sup 0/n and K /sup -/p to K/sup -/p from a high statistics CERN 2-metre hydrogen bubble chamber exposure at 4.15 GeV/c. The behaviour of the differential cross section as a function of four-momentum transfer shows remarkable similarities between the two reactions studied. [...]

Xi */sup -/(2030) production in K/sup -/p reactions at 42 GeV/c / Hemingway, R J ; Armenteros, Rafael ; Bergé, J P ; Díaz, J ; Gay, J B ; Heinen, P M ; Jongejans, B ; Lamb, P R ; Massaro, G G G ; McDowell, W L et al.
Significant production of Xi */sup -/(2030) is observed in the channel K/sup -/p to ( Sigma K)/sup -/K/sup +/ from a high statistics bubble chamber exposure at 4.2 GeV/c. The mass and width are determined to be 2024+or-2 MeV and 16+or-5 MeV respectively. [...]

Backward production of a spin parity 1/sup +/ rho pi enhancement at 104 GeV / Gavillet, P ; Bergé, P ; Blokzijl, R ; De van de Walle, R ; Engeler, J ; Ferrando, A ; Foster, B ; Grossman, P ; Hemingway, R J ; Holmgren, S O et al.
A spin-parity 1/sup +/ rho pi enhancement is observed for the 3 pi mass spectrum in the reaction K/sup -/p to Sigma /sup -/ pi /sup +/ pi /sup +/ pi /sup -/ where events with a small (K/sup -/ to Sigma /sup - /) momentum transfer are selected. The mass (1040 MeV) and width (230 MeV) of this enhancement are reminiscent of the A/sub 1/ to rho pi bump which has mainly been observed in the diffractive-like processes. [...]

A measurement of the eta ' spin parity / Cerrada, M ; Blokzijl, R ; Chaloupka, V ; Foster, B ; Hemingway, R J ; Holmgren, S O ; Jongejans, B ; Losty, Michael J ; Loverre, P F ; Marzano, F et al.
The spin parity of the eta '(958) is studied in the reaction K/sup -/p to eta ' Lambda at 4.2 GeV/c, using bubble chamber data with a statistical sensitivity of 128 events/ mu b. The data unambiguously prefer the 0/sup -/ assignment. [...]

Study of hypercharge exchange reactions of the type K/sup -/p to 1/sup -3///sub 2//sup +or-/ at 42 GeV/c / Aguilar-Benítez, M ; Barreiro, F ; Hemingway, Richard J ; Holmgren, S O ; Losty, Michael J ; Toet, D Z ; Worden, R P ; Zatz, J ; Kluyver, J C ; Massaro, G G G et al.
Results are presented for the quasi two-body hypercharge exchange reactions of the type 0/sup -1///sub 2//sup +/ to 1/sup -3///sub 2 //sup +/, i.e. K/sup -/p to rho /sup -/ Sigma /sup +/(1385) or K/sup - /p to phi Sigma /sup 0/(1385), and 0/sup -1///sub 2//sup +/ to 1/sup -3///sub 2//sup -/, i.e. [...]

The reactions K/sup -/p to lambda pi /sup 0/, Lambda eta , Lambda eta ' at 42 GeV/c / Marzano, F ; Blokzijl, R ; Hemingway, R J ; Hoogland, W ; Kluyver, J C ; Loverre, P F ; Maréchal, B ; Massaro, G G G ; Schrempp, Barbara ; Tiecke, H G et al.
In a high statistics CERN 2 m bubble chamber experiment the different cross sections and polarizations of the Lambda for the reactions K/sup -/p to Lambda pi /sup 0/, Lambda eta , lambda eta ' at 4.2 GeV/c have been measured. The reaction K/sup -/p to Lambda eta exhibits a pronounced dip around -t approximately 0.5 (GeV/c)/sup 2/ and all three reactions show a significant backward peaking (-u<1.0 (GeV/c) /sup 2/). [...]

Spin-parity structure of the (K pi pi )/sup 0/ system produced in the charge-exchange reaction K/sup -/p to (K/sup 0/ pi /sup +/ pi /sup -/) n at 42 GeV/c / Vergeest, J S M ; Cerrada, M ; Chaloupka, V ; Engelen, J J ; Gavillet, P ; Gay, J B ; Hemingway, R J ; Jongejans, B ; Kittel, E W ; Losty, Michael J et al.
A partial wave analysis of the K/sup 0/ pi /sup +/ pi /sup -/ system produced in the charge exchange reaction K/sup -/p to (K/sup 0/ pi /sup +/ pi /sup -/)n at 4.2 GeV/c has been performed both as a function of K pi pi mass and of t'. The 1/sup +/S wave forms the largest contribution to the K pi pi system and peaks at roughly the same mass as the Q in diffractive K pi pi production. [...]

Observation of the B meson in K-p interactions at 42 GeV/c / Flatte, S M ; Blokzijl, R ; Gay, J B ; Grossmann, P ; Hemingway, R J ; Holmgren, S O ; Kluyver, J C ; Lamb, P R ; Losty, Michael J ; Massaro, G G G et al.
A pi omega enhancement at 1245 MeV is observed in the reaction K/sup - /p to Sigma /sup +/ pi /sup -/ omega . Its properties agree with those of a B meson produced by natural-parity exchange thus establishing a coupling of the B to a KK/sup */ system. [...]

Backward production of a spin-parity 1$^{+}$ Krho resonance at 1.28 GeV / Amsterdam-CERN-Nijmegen-Oxford Collaboration
A (K pi pi )/sup +/ mass enhancement is observed in the reactions K /sup -/p to Xi /sup -/K/sup 0+//sub pi //sup +/ pi /sup 0-/ when events with a small (K/sup -/ to Xi /sup -/) four momentum transfer squared are selected. The signal is also visible in the reaction K/sup -/p to Xi /sup -/ pi /sup +/+neutrals. [...]
