In French, Italian, and Romanian, forms inherited from the Latin paradigm 'esse' are used for the copula, the passive auxiliary and tense or perfective auxiliaries. We show that the copula and the passive auxiliary should be identified, while the tense or perfective auxiliaries are different lexemes. Moreover, the copula has the same description across all the Romance languages. While they all are argument inheritance verbs, the copula and the tense or perfective auxiliaries differ with respect to their complement structure: (i) the second only have one complement structure (the complement participle is complement unsaturated), the copula has two complement structures (the predicate is either complement saturated or unsaturated); (ii) French and Italian tense auxiliaries are the head of a flat VP, where the participle is sister to its subcategorized complements, the Romanian perfective auxiliary is the head of a verbal complex; (iii) when the complement predicate is unsaturated, the Romance copula is the head of a flat VP.
Two consequences of the analysis are worth mentioning. First, the copula (and the passive auxiliary) should not be taken into account when stating the environments for auxiliary selection in French and Italian. Second, argument inheritance and complement structure are different phenomena, and argue in favor of theories which systematically distinguish between valence features and constituent structures.
Differential invariant cross sections of light neutral mesons in p-Pb collisions at √sNN = 8.16 TeV and in pp collisions at √s = 8 TeV have been measured up to very high transverse momentum (pT). By combining independent reconstruction techniques available in ALICE using the EMCal and PHOS calorimeters as well as the central barrel tracking detectors, the combined spectra cover almost two orders of magnitude in pT for the π0 meson. The nuclear modification factor RpPb has been measured for the π0 and η mesons and is found to be consistent with NLO pQCD, CGC and energy loss calculations. Comparisons to the RpPb of π0 measured in √sNN = 5.02 TeV hint at a stronger suppression at low pT with increasing collision energy.
How can older adults participate equally in digitisation processes across Europe, and what inclusive research strategies are needed? This Zine summarizes findings from a “Research Innovation Lab on Ageing in a Digital Age”, funded by the VolkswagenStiftung, aiming to bring together 29 docs and postdocs anchored in 26 different disciplines coming from 11 countries, at all stages of their work, to address cutting edge questions relating to ageing in a digital age. Five groups worked together over five days in Frankfurt, Germany, in July 2023 in a creative and interactive hackathon, specific to developing non-technical solutions to social issues of this topic. Moreover, four distinguished experts presented keynote speeches and proposals from various conceptual, methodological and empirical perspectives.
b̄b̄ud tetraquark resonances in the Born-Oppenheimer approximation using lattice QCD potentials
(2019)
We study tetraquark resonances for a pair of static antiquarks b¯b¯ in presence of two light quarks ud based on lattice QCD potentials. The system is treated in the Born-Oppenheimer approximation and we use the emergent wave method. We focus on the isospin I = 0 channel but take different angular momenta l of the heavy antiquarks b¯b¯ into account. Further calculations have already predicted a bound state for the l = 0 case with quantum numbers I(JP) = 0(1+). Performing computations for several angular momenta, we extract the phase shifts and search for T and S matrix poles in the second Riemann sheet. For angular momentum l = 1, we predict a tetraquark resonance with quantum numbers I(JP) = 0(1−), resonance mass m = 10576+4−4 MeV and decay width Γ = 112+90−103 MeV, which decays into two B mesons.
We investigate BB̅ systems by computing potentials of two static quarks in the presence of two quarks of finite mass using lattice QCD. By solving the Schrodinger equation we check whether these potentials are sufficiently attractive to host bound states. Particular focus is put on the experimentally most promising bottomonium-like tetraquark candidate Zb± with quantum numbers I(JP) = 1(1+).
