Test of {CP} Invariance in $\Lambda^0$ Decay

The R608 collaboration Chauvat, P. ; Erhan, S. ; Hayes, K. ; et al.

In an experiment at the CERN intersecting storage rings with √ s = 31 GeV, we have measured αP , the product of asymmetry parameter and polarization, for Λ 0 's and Λ 0 's produced in p p and pp interactions, respectively. The ratio, (αP) Λ /(αP Λ = −1.04±0.29 , is consistent with the value −1, and constitutes the first test of CP invariance in Λ decay.

The ratio CONST/CONST is obtained under assumption of POL(LAMBDA) = POL(LAMBDABAR).

Inclusive $K^0_S$, $\Lambda$ and $\bar{\Lambda}$ Production in 360-{GeV}/$c p p$ Interactions Using the European Hybrid Spectrometer

The EHS-RCBC & Bombay-CERN-Genoa-Innsbruck-Japan-Madrid-Mons-Rutgers-Serpukhov-Tennessee-Vienna collaborations Asai, M. ; Bailly, J.L. ; Banerjee, S. ; et al.
Z.Phys.C 27 (1985) 11, 1985.
Inspire Record 202938 DOI 10.17182/hepdata.16100

Results on cross sections, longitudinal and transverse momentum distributions forKs/0, Λ and\(\bar \Lambda \) production in 360GeV/cpp interactions are presented as obtained from EHS equipped with the Rapid Cycling Bubble Chamber (RCBC). The Λ and\(\bar \Lambda \) polarizations are measured. The cross section for the diffractive components is given using the recoil spectrum. The data are discussed with respect to charm production.

Differences in Leading Baryon Production From $p \bar{p}$ and $p p$ Collisions With $\sqrt{s}=31$-{GeV} at the {CERN} {ISR}

Chauvat, P. ; Cousins, R.D. ; Erhan, S. ; et al.
Phys.Lett.B 127 (1983) 384-388, 1983.
Inspire Record 190333 DOI 10.17182/hepdata.30717

Significant differences are observed between forward-produced Δ ++ (1232) and Λ 0 's in pp interactions and their corresponding anti-particles in p p interactions, as expected from quark counting and single q q annihilation. A possible relationship between these results and the p p -pp total cross section difference is discussed.

The Production of High Momentum Particles and Resonances in $p p$ Collisions at the {CERN} Intersecting Storage Rings

Bobbink, G.J. ; van Driel, M.A. ; Erne, F.C. ; et al.
Nucl.Phys.B 217 (1983) 11-30, 1983.
Inspire Record 181613 DOI 10.17182/hepdata.33961

Data are reported on the momentum distributions of Λ, Λ (1520), φ (1020), Λ and p , inclusively produced between 1° and 2° with respect to one of the primary proton beams at the CERN Intersecting Storage Rings. In addition, the decay angular distribution of the Λ(1520), the ratio of the cross sections for the production of Σ − (1385) and Σ + (1385) and the ratios among different charge states of the pairs Λπ , Λ K, Δ ++ (1232) π and ππ have been measured. These data are confronted with current ideas on fragmentation.

Neutral Strange Particle Production in Proton Proton Collisions at $\sqrt{s}=63$-{GeV}

The CERN-Dortmund-Heidelberg-Warsaw collaboration Drijard, D. ; Fischer, H.G. ; Frehse, H. ; et al.
Z.Phys.C 12 (1982) 217, 1982.
Inspire Record 168038 DOI 10.17182/hepdata.2139

The inclusive cross section for the production ofKs0 mesons, Λ and\(\bar \Lambda\) particles in proton-proton interactions at\(\sqrt s= 63\) GeV is presented. The produced particles have been detected in the full phase space. Behaviour of the longitudinal and transversal depandences of the cross sections are discussed. The total production cross sections fors0 mesons and Λ particles was determined to\(\sigma _{{\rm K}_S^0 }= (25.5 \pm 1.4)\) mb andσΛ=(7.8±1.2) mb respectively. A strong energy dependence of the production cross sections is observed.
