Bose-Fermi U(6/2J+1) Supersymmetries And High-Spin Anomalies

Morrison, I. ; Jarvis, Peter D. ;
Nucl.Phys.A 435 (1985) 461-476, 1985.
Inspire Record 212932 DOI 10.17182/hepdata.17659

A supersymmetric extension of the interacting boson model (IBM) is constructed to describe high-spin anomalies in both even- and odd-mass spectra of the Hg, Pt region (190 ⩽ A ⩽ 200). Supergroup chains such as U ( 6 2j + 1 ) ⊃ Osp ( 6 2j + 1 ) ⊃ O (6) × Sp ( 6 2j + 1 )… U ( 6 2j + 1 ) ⊃ U ( 5 2j + 1 ) ⊃ Osp ( 5 2j + 1 )… incorporate a single j -shell fermion in addition to the usual “s” and “d” bosons ( L = 0 and L = 2). The orthosympletic supergroup reflects the strong pairing force in the subspace of the fermion intruder level. The model agrees favourably with experiment and microscopic calculation.

INCLUSIVE GAMMA AND PI0 PRODUCTION IN K- P INTERACTIONS AT 32-GEV/C. FRANCE-SOVIET UNION AND CERN-SOVIET UNION COLLABORATIONS

Minaenko, A.A. ; Bryukhanova, T.M. ; Kruglov, N.A. ; et al.

Inspire Record 214989 DOI 10.17182/hepdata.2003

The inclusive production of γ's and πp0's inK−p-interactions at 32 GeV/c is studied. About 30.000 γ's coming from a Mirabelle bubble chamber experiment with a sensitivity of 6.5 ev/μb have been used for the analysis. Inclusive and topological cross sections of γ's are measured. The γ invariant differential distributions and their scaling properties are investigated. The inclusive cross section of πp0-production is determined and the πp0 invariant differential distributions are evaluated and compared to those of πp±.

FRAGMENTATION INTO STRANGE PARTICLES IN HIGH-ENERGY NEUTRINO P, neutrino N, ANTI-NEUTRINO P AND ANTI-NEUTRINO N INTERACTIONS

Phys.Lett.B 154 (1985) 231-235, 1985.
Inspire Record 218756 DOI 10.17182/hepdata.30415

The fragmentation of the hadronic system into Λ, Σ(1385), K ) and K ∗ (892) in deep-inelastic charged-current interactions of high energy neutrinos and antineutrinos with proton and neutron is analyzed. The results obtained for the production of these particles from the various initial states are compared with each other and with the predictions of the Lund fragmentation model. This comparison shows that a spectator diquark does not fragment as a whole in a fraction of the interactions. The role of the sea quarks in the baryon formation process is underlined. Strange vector and pseudoscalar mesons are likely to be produced at similar rates.

POLARIZATION EFFECTS IN RHO0 MESON PRODUCTION IN ANTI-PROTON PROTON INTERACTIONS AT 22.4-GEV/C, 12-GEV/C, AND 5.7-GEV/C

Phys.Rev.Lett. 55 (1985) 562-565, 1985.
Inspire Record 221353 DOI 10.17182/hepdata.20274

The ρ0-meson spin alignment is studied in p¯p interactions at 22.4 and 12 GeV/c and in the reaction p¯p→2π++2π−+neutrals at 5.7 GeV/c. An essential ρ0-meson spin alignment is observed. The values of the ρ00T element of the ρ0-meson spin-density matrix in the transversity frame are 0.56 ± 0.07, 0.53 ± 0.05, and 0.54 ± 0.04 for the above-mentioned interactions, respectively. An increase of ρ00T with ρ0 transverse momentum is obtained.

MEASUREMENT OF P (POLARIZED) P (POLARIZED) ---> P P WITH A 16.5-GEV/C POLARIZED PROTON BEAM

Brown, K.A. ; Bruni, R.J. ; Cameron, P.R. ; et al.
Phys.Rev.D 31 (1985) 3017-3020, 1985.
Inspire Record 220234 DOI 10.17182/hepdata.23579

Using the new Brookhaven Alternating Gradient Synchrotron polarized proton beam and our polarized proton target, we measured the spin-spin correlation parameter Ann in 16.5-GeV/c proton-proton elastic scattering. We found an Ann of (6.1±3.0)% at P⊥2=2.2 (GeV/c)2. We also measured the analyzing power A in two independent ways, providing a good test of possible experimental errors. Comparing our new data with 12-GeV Argonne Zero Gradient Synchrotron data shows no evidence for strong energy dependence in Ann in this medium-P⊥2 region.
