Identical neutral kaon pair correlations are measured in √s=7 TeV pp collisions in the ALICE experiment. One-dimensional Ks0Ks0 correlation functions in terms of the invariant momentum difference of kaon pairs are formed in two multiplicity and two transverse momentum ranges. The femtoscopic parameters for the radius and correlation strength of the kaon source are extracted. The fit includes quantum statistics and final-state interactions of the a0/f0 resonance. Ks0Ks0 correlations show an increase in radius for increasing multiplicity and a slight decrease in radius for increasing transverse mass, mT, as seen in ππ correlations in pp collisions and in heavy-ion collisions. Transverse mass scaling is observed between the Ks0Ks0 and ππ radii. Also, the first observation is made of the decay of the f2′(1525) meson into the Ks0Ks0 channel in pp collisions.
A measurement of the multi-strange Ξ− and Ω− baryons and their antiparticles by the ALICE experiment at the CERN Large Hadron Collider (LHC) is presented for inelastic proton–proton collisions at a centre-of-mass energy of 7 TeV. The transverse momentum (pT) distributions were studied at mid-rapidity (|y|<0.5) in the range of 0.6<pT<8.5 GeV/c for Ξ− and Ξ¯+ baryons, and in the range of 0.8<pT<5 GeV/c for Ω− and Ω¯+. Baryons and antibaryons were measured as separate particles and we find that the baryon to antibaryon ratio of both particle species is consistent with unity over the entire range of the measurement. The statistical precision of the current data has allowed us to measure a difference between the mean pT of Ξ− (Ξ¯+) and Ω− (Ω¯+). Particle yields, mean pT, and the spectra in the intermediate pT range are not well described by the PYTHIA Perugia 2011 tune Monte Carlo event generator, which has been tuned to reproduce the early LHC data. The discrepancy is largest for Ω− (Ω¯+). This PYTHIA tune approaches the pT spectra of Ξ− and Ξ¯+ baryons below pT<0.85 GeV/c and describes the Ξ− and Ξ¯+ spectra above pT>6.0 GeV/c. We also illustrate the difference between the experimental data and model by comparing the corresponding ratios of (Ω−+Ω¯+)/(Ξ−+Ξ¯+) as a function of transverse mass.
Ziel des Beitrags ist die Darstellung der neuartigen Prototypen MultiGenera und MultiComb, die auf der Grundlage des multilingualen Valenzwörterbuchs zur Nominalphrase PORTLEX syntaktisch-semantische valenzbasierte Auskunft über die Nominalphrase sowie über ihren Satzrahmen anbieten. Nach der Schilderung der Haupteigenschaften der Ressourcen sowie des zugrunde liegenden methodologischen Verfahrens werden Hinweise über ihre möglichen didaktischen Anwendungsbereiche gegeben.
Ausgehend von der Engelschen Auffassung der Situativergänzungen wird hier an die Adverbialia mittels neu vorgeschlagener analytischer Verfahren herangegangen. Diese Studie leistet zum einen eine einheitliche Beschreibung bestimmter Verben - "stattfinden", "gebären", "sterben", "erschehen", "anfangen", "öffnen" und "beginnen" - und bietet zum anderen syntaktische, semantische, morphosyntaktische und kommunikative Unterscheidungsmittel für strittige Fälle bei der Unterscheidung zwischen adverbialen Ergänzungen und adverbialen Angaben. Das in diesem Aufsatz Dargestellte kann akzeptiert oder revidiert werden, aber der empirische Teil zeigt eindeutige Ergebnisse.
This article provides an overview of valence lexicography and focuses especially on the Spanish-German case. Based on valence dictionaries and ongoing projects that describe the languages mentioned, this paper addresses the question of equivalence considering both quantitative and qualitative parameters and the various diffi culties found out through the process of description. A central role is ascribed to the problems surrounding the selection and description of equivalence in non-standard cases. Discussion of new theoretical and practical proposals is also included.
