THRUST DISTRIBUTIONS AND DECAYS OF THE UPSILON BOUND STATES

Peterson, D. ; Bohringer, T. ; Franzini, P. ; et al.
Phys.Lett.B 114 (1982) 277-281, 1982.

We have studied the topologies of hadronic events in e + e - annihilation data taken in the region of the upsilon resonances with the non-magnetic CUSB detectors at CESR. Using a thrust-like variable we compare the decay of ϒ, ϒ′ and ϒPrime; find for ϒ″ a significant excess of high thrust events, which we interpret as evidence for electric dipole transitions.

We have observed ϱ 0 production in e + e − annihilation to hadrons at high energies. The differential cross section at a centre of mass energy W , of 34 GeV, is presented. In the range 0.2< x < 0.7, we measure 0.33 ± 0.06 (stat.) ± 0.07 (syst.), 0.22 ± 0.06 ± 0.05 and 0.22 ± 0.02 ± 0.05 ϱ 0 /event at W = 14, 22 and 34 GeV respectively.

A Partial Wave Analysis of the $K^- \phi$ System Produced in the Reaction $K^- p \to K^+ K^- K^- p$ at 18.5-{GeV}/$c$

The Bari-Birmingham-CERN-Milan-Paris-Pavia collaboration Armstrong, T. ; Baubillier, M. ; Beusch, W. ; et al.
Nucl.Phys.B 221 (1983) 1-15, 1983.
Inspire Record 180924 DOI 10.17182/hepdata.33954

About 15 000 K − Φp events have been collected in the CERN Ω′ spectrometer. A partial-wave decomposition of the K − Φ system is performed. The 1 + SO + wave is dominant. The 0 − P0 + and 2 − P0 + waves are important and show resonant behaviour at ∼ 1.83 GeV (Γ ∼ 0.25 GeV) and ∼ 1.73 GeV (Γ ∼ 0.22 GeV) respectively. The first one can be interpreted as the second radial excitation of the kaon while the second one can be identified as one of the two L mesons.

Large Transverse Momentum Particle Production in $\alpha \alpha$ and $p p$ Collisions at the {CERN} {ISR}

The Axial Field Spectrometer collaboration Akesson, T. ; Albrow, M.G. ; Almehed, S. ; et al.
Nucl.Phys.B 209 (1982) 309-320, 1982.
Inspire Record 178882 DOI 10.17182/hepdata.34016

The production of charged hadrons with high p T in αα collisions at √ s =126 GeV and pp collisions at √ s =31 and 63 GeV is compared, and the structure of the events associated with the high- p T particles is studied. The probability of finding associated particles close to the trigger particle increases strongly between √ s =31 and 63 GeV for pp collisions. For p T >2.5GeV/ c the αα/pp cross section ratio at the same energy per nucleon is measured to be 18.7 ± 2.0, to be compared with A 2 = 16, and a higher associated multiplicity is observed for αα.

A Measurement of the Inclusive Cross-section of Charged Pions at Very High Transverse Momenta

The CERN-Dortmund-Heidelberg-Warsaw collaboration Drijard, D. ; Fischer, H.G. ; Frehse, H. ; et al.
Nucl.Phys.B 208 (1982) 1-11, 1982.
Inspire Record 178573 DOI 10.17182/hepdata.30565

The inclusive cross sections for the production of high transverse momentum π + and π − mesons in proton-proton interactions have been measured at the highest ISR energy √ s = 63 GeV and at a c.m. production angle of 50°. The cross sections for π + and π − mesons are compared as a function of transverse momentum. It is shown that the inclusive cross section of π − mesons decreases faster than the π + cross section. particle σ ( π ± )/ σ (charged particles) are presented as a function of transverse momentum.
