Charmed pair correlations in pi- Cu interactions at 230-GeV/c.

The ACCMOR collaboration Barlag, S. ; Becker, H. ; Bożek, A. ; et al.
Phys.Lett.B 302 (1993) 112-118, 1993.
Inspire Record 362064 DOI 10.17182/hepdata.28956

In the CERN NA32 experiment a high-resolution silicon vertex detector and a purely topological approach were used to collect 557 events consistent with associated charm production, both decay vertices being observed. The pseudorapidity gap distribution appears to be nearly independent of the nature of the charmed hadrons. This distribution is reasonably consistent with the next-to-leading order QCD calculations. However the azimuthal-angle distribution is significantly broader than the above predictions.

A Measurement of jet shapes in p anti-p collisions at s**(1/2) = 1.8-TeV

The CDF collaboration Abe, F. ; Amidei, Dante E. ; Anway, Carol E. ; et al.
Phys.Rev.Lett. 70 (1993) 713-717, 1993.
Inspire Record 340125 DOI 10.17182/hepdata.19744

We present a measurement of jet shapes in p¯p collisions at √s =1.8 TeV at the Fermilab Tevatron using the Collider Detector at Fermilab (CDF). Qualitative agreement is seen with the predictions of recent next-to-leading [O(αs3)] calculations and with leading logarithm QCD based Monte Carlo simulations. The dependence of the jet shape on transverse energy is studied.

Neutral strange particle production in K+ and pi+ collisions with Al and Au nuclei at 250-GeV/c

The NA22 collaboration Botterweck, F. ; Charlet, M. ; Chliapnikov, P.V. ; et al.
Z.Phys.C 55 (1992) 373-382, 1992.
Inspire Record 333307 DOI 10.17182/hepdata.14584

Data are presented on inclusiveKs0 and Λ production inK+ and π+ collisions with Al and Au nuclei at 250 GeV/c. Results are given on total inclusive cross sections and theA dependence, as well as on distributions in Feynman-xF, rapidityy and transverse momentum. Ratios ofKS0 and of Λ to π+ production are presented. The data are compared with predictions of the quark-parton model FRITIOF.

Transverse momentum of dimuons production in p U, O U and S U collisions at 200-GeV/nucleon.

The NA38 collaboration Abreu, M.C. ; Alimi, M. ; Baglin, C. ; et al.
Nucl.Phys.A 525 (1991) 469C-472C, 1991.
Inspire Record 328922 DOI 10.17182/hepdata.36783

Dimuon production m p-U, O-U and S-U collisions has been studied at 200 GeV/N. It is observed that 〈 p T 〉 and 〈 p 2 T 〉 of the J / Ψ transverse momentum distributions increase with the transverse energy of the ion induced reactions. Such a marked behaviour is not seen for muon pairs of the continuum.

A Study of massive electron pairs and associated particles produced at the CERN ISR

The CERN-Michigan State-Oxford-Rockefeller collaboration Angelis, A.L.S. ; Basini, G. ; Besch, H.J. ; et al.
Nucl.Phys.B 348 (1991) 1-22, 1991.
Inspire Record 298427 DOI 10.17182/hepdata.33054

A sample of 105 e + e − events with an invariant mass greater than 11 GeV/ c 2 produced in pp collisions at a center-of-mass energy of 62.3 GeV is discussed. Cross sections are presented as a function of mass and transverse momentum. The multiplicity, transverse momentum, and azimuthal dependence of associated particles are also studied.
