Xi- and Anti-xi+ Production in $\pi^- p$ Interactions at 16-{GeV}/$c$

Balea, E. ; Berceanu, S. ; Coca, C. ; et al.

Nucl.Phys.B 150 (1979) 345-356, 1979.

Inspire Record 131824 DOI 10.17182/hepdata.34790

Production of Ξ − and Ξ + hyperons has been studied in 16 GeV/ c π − p interactions. Cross sections are given for Ξ − and gX + production. Distributions and average values of c.m. production angle, transverse and longitudinal variables are presented. Characteristics of some Ξ final states identified are also presented.

NEUTRAL STRANGE PARTICLE PRODUCTION IN PI- P INTERACTIONS AT 16-GEV/C

Balea, E. ; Berceanu, S. ; Coca, C. ; et al.

Nucl.Phys.B 163 (1980) 21-45, 1980.

Inspire Record 157169 DOI 10.17182/hepdata.8077

The production of K S 0 , Λ and Λ in π − p ractions at 16 GeV/ c is investigated. Cross sections for single strange particles are determined, both inclusively and as functions of the charged multiplicity. Some characteristics of the multiplicity distributions are also discussed. Inclusive distributions are studied as a function of the longitudinal and transverse variables of V 0 and the missing mass squared. The average charged multiplicities of the systems recoiling against the Λ and K S 0 are presented.

Inclusive Production of Anti-xi+ and $\Xi^-$ in $K^+ p$ Interactions at 32-{GeV}/c

Azhinenko, I.V. ; Belokopytov, Yu.A. ; Chliapnikov, P.V. ; et al.

Nucl.Phys.B 176 (1980) 51, 1980.

Inspire Record 153556 DOI 10.17182/hepdata.11096

The inclusive production of Ξ + and Ξ − hyperons is investigated in K + p interactions at 32 GeV/ c . The production cross sections, 36.4±9 μ b for the Ξ + and 6.5±3 μ b for the Ξ − , are rising strongly with energy similarly to Λ and Λ production in K + p interactions. The Ξ + are produced preferentially in the forward direction in the c.m.s., while the Ξ − are produced dominantly backwards. The average transverse momenta 〈p T 〉 Ξ + =0.73±0.09 GeV /c and 〈 p T 〉 Ξ − =0.58±0.09 GeV/ c .

Inclusive $\phi$ Production in $K^+ p$ Interactions at 70-{GeV}/$c$

The Brussels-CERN-Genoa-Mons-Nijmegen-Serpukhov collaboration Barth, M. ; De Clercq, C. ; De Wolf, E.A. ; et al.

Phys.Lett.B 117 (1982) 267-271, 1982.

Inspire Record 178885 DOI 10.17182/hepdata.41158

We present results on inclusive φ meson production in K + p interactions at 70 GeV/ c in the kaon fragmentation x >0.2 region. Comparison with other data on φ meson production in K ± and p induced reactions provides evidence that the strange valence-quark fragmentation or recombination processes play the dominant role in the K ± → φ transitions. Arguments are presented that the kaon valence strange s -quark carries a much higher momentum fraction than the u-quark. Evidence for the previously observed narrow φπ + state at mass ∼2.1 GeV is discussed.
