Inelastic Interactions Between 6.8-BeV/c $\pi^-$ Mesons and Nucleons

Inspire Record 1387796 DOI 10.17182/hepdata.17077

An analysis was made of 355 interactions between 1r- mesons and nucleons. The momentum and angular distributions of the secondary charged particles were measured. Information on 1r0 mesons produced in the interactions has been obtained. The experimental data are compared with the statistical theory. The results suggest that peripheral interactions may exist. In events of low multiplicity (two-prong cases) "one-meson" peripheral interactions play an important role, while in events of large multiplicity an important role is played by interactions not of the one-meson type, among which also central collisions are possible.

Charged-particle multiplicities in pp interactions measured with the ATLAS detector at the LHC

New J.Phys. 13 (2011) 053033, 2011.
Inspire Record 882098 DOI 10.17182/hepdata.57077

Measurements are presented from proton-proton collisions at centre-of-mass energies of sqrt(s) = 0.9, 2.36 and 7 TeV recorded with the ATLAS detector at the LHC. Events were collected using a single-arm minimum-bias trigger. The charged-particle multiplicity, its dependence on transverse momentum and pseudorapidity and the relationship between the mean transverse momentum and charged-particle multiplicity are measured. Measurements in different regions of phase-space are shown, providing diffraction-reduced measurements as well as more inclusive ones. The observed distributions are corrected to well-defined phase-space regions, using model-independent corrections. The results are compared to each other and to various Monte Carlo models, including a new AMBT1 PYTHIA 6 tune. In all the kinematic regions considered, the particle multiplicities are higher than predicted by the Monte Carlo models. The central charged-particle multiplicity per event and unit of pseudorapidity, for tracks with pT >100 MeV, is measured to be 3.483 +- 0.009 (stat) +- 0.106 (syst) at sqrt(s) = 0.9 TeV and 5.630 +- 0.003 (stat) +- 0.169 (syst) at sqrt(s) = 7 TeV.

Multiplicity distribution in p n interaction at 400-GeV/c and its empirical regularity

Bhattacharjee, D.K. ; Cherian, P.J. ; Maity, D.K. ;
Phys.Rev.D 41 (1990) 9-12, 1990.
Inspire Record 299994 DOI 10.17182/hepdata.22897

Multiplicity distributions in pn interactions derived from 400-GeV/c pd data are presented along with other available pn data at and above 100 GeV/c. Charged multiplicities are seen to be negative-binomially distributed. Moments of distribution and different parameters of fit are evaluated and compared. The rise of the single-diffractive component in pn interactions from 100 to 400 GeV is observed to be compatible with that in pp interactions in the same energy range.

A Detailed Study of Strange Particle Production in $e^+ e^-$ Annihilation at High-energy

Results onK0 and Λ production ine+e− annihilation at c.m. energies of 14, 22 and 34 GeV are presented. The shape of theK0 and Λ differential cross sections are very similar to each other and to those of π±,K± and\(p(\bar p)\). Scaling violations are observed forK0 production. We obtain a value for the probability to produce strange quark-antiquark pairs relative to that to produce up or down quark-antiquark pairs of 0.35±0.02±0.05. The value ofRh=σ(e+e-→hX)/σµµ is shown to rise steadily with c.m. energy for all particle species. At 34 GeV we find 1.48±0.05K0 and 0.31±0.03 Λ per event. We have searched for possible Λ polarization. The production ofK0's and Λ's in jets is examined as a function ofpT2 and rapidity and compared to that of all charged particles; the yields in two and three jets are also investigated. Results are presented from events with two baryons\((\Lambda ,\bar \Lambda ,por\bar p)\) observed.
