Measurement of single spin asymmetry for direct photon production in p p collisions at 200-GeV/c

The E704 collaboration Adams, D.L. ; Achurin, N. ; Belikov, N.I. ; et al.
Phys.Lett.B 345 (1995) 569-575, 1995.
Inspire Record 399938 DOI 10.17182/hepdata.28766

The single spin asymmetry for inclusive direct-photon production has been measured using a polarized proton beam of 200 GeV/c with an unpolarized proton target at −0.15 < xf < 0.15 and 2.5 < pt < 3.1 GeV/c at Fermilab. The data on the cross section for pp → γX at 2.5 < pt < 3.8 GeV/c are also provided. The measurement was done using lead-glass calorimeters and photon detectors which surrounded the fiducial area of the calorimeters. Background rejection has been done using these surrounding photon detectors. The cross section obtained is consistent with the results of previous measurements assuming a nuclear dependence of A 1.0 . The single spin asymmetry, A N , for the direct-photon production is consistent with zero within experimental uncertainty.

Single spin asymmetries and invariant cross-sections of the high transverse momentum inclusive pi0 production in 200-GeV/c p p and anti-p p interactions

The FNAL E704 collaboration Adams, D.L. ; Akchurin, N. ; Belikov, N.I. ; et al.
Phys.Rev.D 53 (1996) 4747-4755, 1996.
Inspire Record 382392 DOI 10.17182/hepdata.40544

The π0 inclusive and semi-inclusive, single-spin asymmetries have been measured using transversely polarized, 200-GeV/c proton and antiproton beams colliding with an unpolarized hydrogen target. The measured asymmetries are consistent with zero within the experimental uncertainties for the kinematic region -0.15

The data on invariant cross sections of deuterons emitted in the interactions of 3He with C, Cu and Pb targets at 4.9 GeV/nucleon are given. Inclusive spectra of deuterons produced in the reactions were measured from 20 deg to 150 deg in the laboratory frame with 10 deg step. Measurements were made on external 3He-beam at Dubna synchrophasotron

Inclusive $K^*$+ (890), $K^*$+ (1430) and $\bar{K}^*$ (890) Production in $K^+ p$ Interactions at 32-{GeV}/$c$

Azhinenko, I.V. ; Belokopytov, Yu.A. ; Borovikov, A.A. ; et al.
Z.Phys.C 25 (1984) 103, 1984.
Inspire Record 195755 DOI 10.17182/hepdata.47703

We present final results on inclusive production ofK*+(890),K*+(1430) andK*−(890) in\(\bar K^ +p\) interactions at 32 GeV/c, based on a statistics of ∼27 events/μb. Total cross sections,pT-andx-dependence of inclusive distributions are compared with experiments at other energies and with the Lund fragmentation model. Spin density matrix elements of theK*+(890) are also discussed. The results suggest that “recombination” of both initial state valence quarks\(\bar s\) andu of theK+ intoK*+(890), responsible in the Lund model for ∼45% of theK*+(890) cross section, is strongly suppressed.
