The D0 collaboration Abazov, V.M. ; Abbott, B. ; Abolins, M. ; et al.

Phys.Rev.Lett. 94 (2005) 232001, 2005.

Inspire Record 676877 DOI 10.17182/hepdata.51525

We present measurements of the inclusive production cross sections of the Upsilon(1S) bottomonium state in ppbar collisions at sqrt(s) = 1.96 TeV. Using the Upsilon(1S) to mu+mu- decay mode for a data sample of 159 +- 10 pb^-1 collected by the D0 detector at the Fermilab Tevatron collider, we determine the differential cross sections as a function of the Upsilon(1S) transverse momentum for three ranges of the Upsilon(1S) rapidity: 0 < |y| < 0.6, 0.6 < |y| < 1.2, and 1.2 < |y| < 1.8.

Inclusive Production Cross-Sections of Resonances in 32-GeV/c K+ p Interactions

The French-Soviet & CERN-Soviet collaborations Granet, P. ; Mosca, L. ; Saudraix, J. ; et al.

Nucl.Phys.B 140 (1978) 389, 1978.

Inspire Record 121746 DOI 10.17182/hepdata.34983

The inclusive production of resonances is systematically studied in K + p interactions at 32 GeV/ c . Total production cross sections are given for three baryon resonances, five vector and three 2 + tensor mesons. We also compare the central and fragmentation components of the total production cross sections with quark model predictions.

Inclusive particle production in 400-GeV/c p p interactions

Aguilar-Benitez, M. ; Allison, W.W. W. ; Batalov, A.A. ; et al.

Z.Phys.C 50 (1991) 405-426, 1991.

Inspire Record 314091 DOI 10.17182/hepdata.1435

We report on a study of inclusive particle production in pp-interactions at 400 GeV/c. The data are based on 472 K reconstructed events recorded in the NA 27 experiment using the LEBC-EHS facility at CERN. The production cross sections are determined of pseudo scalar (π±,0, η andK±), scalar (f0(975)), vector (ρ±,0(770), ω(783), ϕ(1020),K*0(892), and$\bar K^{ * 0} $(892)), and tensorf0 mesons, of protons and antiprotons, and theΔ++,+,0(1232), and Λ(1520) baryon resonances in the forward hemisphere of the center of mass system, as well as longitudinal and transverse momentum distributions. The results are compared with predictions of the FRITIOF model and with other experimental data.

NEUTRAL STRANGE PARTICLE PRODUCTION IN PI- P INTERACTIONS AT 16-GEV/C

Balea, E. ; Berceanu, S. ; Coca, C. ; et al.

Nucl.Phys.B 163 (1980) 21-45, 1980.

Inspire Record 157169 DOI 10.17182/hepdata.8077

The production of K S 0 , Λ and Λ in π − p ractions at 16 GeV/ c is investigated. Cross sections for single strange particles are determined, both inclusively and as functions of the charged multiplicity. Some characteristics of the multiplicity distributions are also discussed. Inclusive distributions are studied as a function of the longitudinal and transverse variables of V 0 and the missing mass squared. The average charged multiplicities of the systems recoiling against the Λ and K S 0 are presented.

K*0 and phi Meson Production in Proton-Nucleus Interactions at sqrt(s) = 41.6 GeV

The HERA-B collaboration Abt, I. ; Adams, M. ; Agari, M. ; et al.

Eur.Phys.J.C 50 (2007) 315-328, 2007.

Inspire Record 719788 DOI 10.17182/hepdata.43089

The inclusive production cross sections of the strange vector mesons K*0, K*0bar, and phi have been measured in interactions of 920 GeV protons with C, Ti, and W targets with the HERA-B detector at the HERA storage ring. Differential cross sections as a function of rapidity and transverse momentum have been measured in the central rapidity region and for transverse momenta up to pT=3.5 GeV/c. The atomic number dependence is parametrised as sigma(pA) = sigma(pN)*A**alpha, where sigma(pN) is the proton-nucleon cross section. Within the phase space accessible, alpha(K*0) = 0.86+/-0.03, alpha(K*0bar) = 0.87+/-0.03, and alpha(phi) = 0.96+/-0.02. The total proton-nucleon cross sections, determined by extrapolating the differential measurements to full phase space, are sigma(pN->K*0) = 5.06+/-0.54 mb, sigma(pN->K*0bar) = 4.02+/-0.45 mb, and sigma(pN->phi) = 1.17+/-0.11 mb. The Cronin effect is observed for the first time for vector mesons containing strange quarks/ compared to the measurements of Cronin et al. for K+- mesons, the measured values of alpha for phi mesons coincide with those of K- mesons for all transverse momenta, while the enhancement for K*0 / K*0bar mesons is smaller.

The inclusive single-particle spectra of pi-, K0(s) and Lambda in proton proton collisions at 19-GeV/c

The Scandinavian Bubble Chamber collaboration Boeggild, H. ; Dahl-Jensen, E. ; Hansen, K.H. ; et al.

Nucl.Phys.B 57 (1973) 77-99, 1973.

Inspire Record 84068 DOI 10.17182/hepdata.32535

Data on the inclusive production spectra of K S 0 and Λ from proton-proton collisions at 19 GeV are presented and discussed in connection with the earlier studied inclusive π − production spectrum. The three single-particle spectra are compared with a crude two-center thermal model for the average radiation from the pp collisions.
