Bottomonium and Drell-Yan production in p-A collisions at 450- GeV

The NA50 collaboration Alessandro, B. ; Alexa, C. ; Arnaldi, R. ; et al.
Phys.Lett. B635 (2006) 260-269, 2006.
Inspire Record 712992 DOI 10.17182/hepdata.57411

The NA50 Collaboration has measured heavy-quarkonium production in p-A collisions at 450 GeV incident energy (sqrt(s) = 29.1 GeV). We report here results on the production of the Upsilon states and of high-mass Drell-Yan muon pairs (m > 6 GeV). The cross-section at midrapidity and the A-dependence of the measured yields are determined and compared with the results of other fixed-target experiments and with the available theoretical estimates. Finally, we also address some issues concerning the transverse momentum distributions of the measured dimuons.

Drell-Yann (for the mass region MMUMU>6GeV/c**2) and bottomonium cross sections, and their ratio.

Mean pT and Mean PT**2 for Drell-Yann (4.5<MMUMU<8 GeV/c**2) Errors for Drell-Yann are purely statistical, error value for Upsilon includes a systematical error due to uncertianty in the extrapolation of the drell-yann yield into the upsilon region. The total error is anyway dominated by the statistical contribution.

J/psi and psi-prime production and their normal nuclear absorption in proton-nucleus collisions at 400-GeV

The NA50 collaboration Alessandro, B. ; Alexa, C. ; Arnaldi, R. ; et al.
Eur.Phys.J. C48 (2006) 329, 2006.
Inspire Record 733916 DOI 10.17182/hepdata.57412

We report a new measurement of J/psi, psi' and Drell-Yan cross-sections, in the kinematical domain $-0.425&lt;y_{\rm cm}&lt;0.575$ and $-0.5&lt;\cos\theta_{\rm CS}&lt;0.5$, performed at the CERN-SPS using 400 GeV/c incident protons on Be, Al, Cu, Ag, W and Pb targets. The dependence of the charmonia production cross-sections on the size of the target nucleus allows to quantify the so-called normal nuclear absorption. In the framework of the Glauber model, this new measurement is combined with results previously obtained with the same apparatus, under different experimental conditions, and leads to a precise determination of the J/psi and psi' absorption cross-sections in the surrounding nuclear matter.

Parton energy loss limits and shadowing in Drell-Yan dimuon production

The NuSea collaboration Vasilev, M.A. ; Beddo, M.E. ; Brown, C.N. ; et al.
Phys.Rev.Lett. 83 (1999) 2304-2307, 1999.
Inspire Record 501230 DOI 10.17182/hepdata.19445

A precise measurement of the ratios of the Drell-Yan cross section per nucleon for an 800 GeV/c proton beam incident on Be, Fe and W targets is reported. The behavior of the Drell-Yan ratios at small target parton momentum fraction is well described by an existing fit to the shadowing observed in deep-inelastic scattering. The cross section ratios as a function of the incident parton momentum fraction set tight limits on the energy loss of quarks passing through a cold nucleus.

Observation of polarization in bottomonium production at $\sqrt{s}$ = 38.8-GeV

The NuSea collaboration Brown, C.N. ; Awes, T.C. ; Beddo, M.E. ; et al.
Phys.Rev.Lett. 86 (2001) 2529-2532, 2001.
Inspire Record 536629 DOI 10.17182/hepdata.19423

We present a measurement of the polarization observed for bottomonium states produced in p-Cu collisions at sqrt(s)=38.8 GeV. The angular distribution of the decay dimuons of the Upsilon(1S) state show no polarization at small xF and pT but significant positive transverse production polarization for either pT > 1.8 GeV/c or for xF > 0.35. The Upsilon(2S+3S) unresolved states show a large transverse production polarization at all values of xF and pT measured. These observations are compared with an NRQCD calculation that predicts a transverse polarization in bottomonium production arising from quark-antiquark fusion and gluon-gluon fusion diagrams.
