Lemoigne, Y. ; Barate, R. ; Bareyre, P. ; et al.

Phys.Lett.B 113 (1982) 509, 1982.

Inspire Record 176731 DOI 10.17182/hepdata.30918

The χ 1 ++ (3507) and the χ 2 ++ (3553) states have been observed in the Goliath spectrometer at the CERN SPS in 185 GeV/ c π − -Be collisions. Their radiative decays contribute 27.7% (for the χ 1 ++ ) and 12.8% (for the χ 2 ++ ) to J ϕ production. At this energy, their cross sections are 65±19 nb and 96±29 nb, respectively

Phys.Lett.B 113 (1982) 190-194, 1982.

Inspire Record 177090 DOI 10.17182/hepdata.30958

The reaction e + e - → e + e - η' has been observed in the JADE experiment at PETRA, by detecting the final state π + π - γ, resulting from the decay η' → γϱ 0 . The cross section was measured at an average beam energy of 17.15 GeV to be σ(e + e - → e + e - η') = 2.2 ± 0.2 (stat.) ± 0.4(syst.) nb, yielding the radiative width Γ η'γγ = 5.0 ± 0.5(stat.) ± 0.9 (syst.) keV.

Transverse Momentum Distributions of Hadrons Produced in $\alpha \alpha$ and $\alpha p$ Collisions at the {CERN} Intersecting Storage Rings

The CERN-Heidelberg-Lund collaboration Bell, W. ; Braune, K. ; Claesson, G. ; et al.

Phys.Lett.B 112 (1982) 271-276, 1982.

Inspire Record 176957 DOI 10.17182/hepdata.30920

The inclusive production of charged hadrons has been measured in αα and αp collisions at nucleon-nucleon c.m. energies (√s nn )of 31 and 44 GeV, respectively, for transverse momenta p T up to 5 GeV/ c in the central rapidity ( y ) region. at high p T the yields are consistent with being 4 times and 16 times highere than the ones in pp interactions at y =0, for αp and αα interactions, respectively. However, an enhancement over these factors, as expected from an earlier FNAL experiment, cannot be ruled out.

Measurement of Polarized Target Asymmetry in $\gamma d \to p n$ in the Photon Energy Region Between 0.3-{GeV} and 0.7-{GeV}

Ohashi, Y. ; Awaji, N. ; Hayashii, H. ; et al.

Phys.Lett.B 110 (1982) 441-444, 1982.

Inspire Record 176585 DOI 10.17182/hepdata.30974

The target asymmetry in γ d → pn has been measured at proton c.m. angles of 70°, 100° and 130° in the photon energies between 0.3 and 0.7 GeV. Results show relatively small asymmetry values in contrast to large proton polarizations. A phenomenological analysis by Ikeda et al. does not reproduce the present data, especially in the lower energy region.

Charged Pion Production in $e^+ e^-$ Annihilation at 14-{GeV}, 22-{GeV} and 34-{GeV} Center-of-mass Energy

The TASSO collaboration Brandelik, R. ; Braunschweig, W. ; Gather, K. ; et al.

Phys.Lett.B 113 (1982) 98-104, 1982.

Inspire Record 176886 DOI 10.17182/hepdata.30892

The inclusive production of π ± mesons in e + e − annihilation has been measured at c.m. energies of 14, 22 and 34 GeV for pion momenta between 0.3 ans 10 GeV/ c . The fraction of pions among the charged hadrons is above 90% at 0.4 GeV/ c and decreases to about 50% at high momenta. The scaled cross sections ( s β ) d σ d x at 14, 22 and 34 GeV as well as the 5.2 GeV data from DASP have a rather similar x dependence. After integration over the x range from 0.2 to 0.6 the cross sections indicate a monotonic decrease with increasing centre-of-mass energy.

A Measurement of Sigma(tot) (e+ e- ---> Hadrons) for CM Energies Between 12.0-GeV and 36.7-GeV

The TASSO collaboration Brandelik, R. ; Braunschweig, W. ; Gather, K. ; et al.

Phys.Lett.B 113 (1982) 499-508, 1982.

Inspire Record 176887 DOI 10.17182/hepdata.6666

The ration R = σ (e + e − → hadrons) σ μμ was measured between 12.0 and 36.7 GeV c.m. energy W with a precision of typically ± 5.2%. R is found to be constant with an average R = 4.01 ± 0.03 (stat) ± (syst.) for W ⩾ 14 GeV. Quarks are found to be point-like, the mass parameter describing a possible quark form-factor being larger than 186 GeV. Fits including QCD corrections and a weak neutral-current contribution are presented.

Inclusive Strange Resonance Production in $p p$, $\pi^+ p$ and $K^+ p$ Interactions at 147 GeV/c

Brick, D. ; Rudnicka, H. ; Shapiro, A.M. ; et al.

Phys.Rev.D 25 (1982) 2248-2258, 1982.

Inspire Record 176545 DOI 10.17182/hepdata.23976

We have studied the inclusive production of K*±(890) and Y*±(1385) in pp, π+p, and K+p interactions at 147 GeV/c. The experiment used the Fermilab 30-inch hydrogen bubble chamber with the hybrid spectrometer system. Results are based on a sample of 1916 observed KS and 932 observed A. Inclusive cross sections are given for K*± and Y*± production from the three beams, and comparisons are made with experiments at other energies. Feynman-x and transverse-momentum-squared distributions are also calculated. The results suggest that the K*− is entirely produced in the central region, while the K*+ includes a component from beam fragmentation. Comparisons are made with the additive quark model.

A Study of Deep Inelastic Hadron - Hadron Collisions with a Large Acceptance Calorimeter Trigger

The Bari-Cracow-Liverpool-Munich-Nijmegen collaboration De Marzo, C. ; De Palma, M. ; Distante, A. ; et al.

Phys.Lett.B 112 (1982) 173-177, 1982.

Inspire Record 176541 DOI 10.17182/hepdata.34014

Large transverse energy cross sections of 300 GeV/ c pions and protons on hydrogen have been measured with a segmented calorimeter covering the central rapidity region −0.88 < y < 0.67 and 2 π in azimuth. The selected events show large multiplicities and no jet-like event structure. Processes more complicated than the scattering of two constituents appear to dominate these inelastic collisions.
