First measurement of the charge asymmetry in beauty-quark pair production.
2014
The difference in the angular distributions between beauty quarks and antiquarks, referred to as the charge asymmetry, is measured for the first time in b[bar over b] pair production at a hadron collider. The data used correspond to an integrated luminosity of 1.0 fb[superscript −1] collected at 7 TeV center-of-mass energy in proton-proton collisions with the LHCb detector. The measurement is performed in three regions of the invariant mass of the b[bar over b] system. The results obtained are A[b[bar over b] over C](40 105 GeV/c[superscript 2]) = 1.6 ± 1.7 ± 0.6%, where A[b[bar over b] over C] is defined as the asymmetry in the difference in rapidity between jets formed from the beauty q…
Information Disclosure and Sustainable Competitive Advantage: Evidence from the Spanish Tourism Industry
2022
Of all the resources and capabilities that have a well-established impact on decision-making, information stands out. With the advent of the digital economy, organizations have been making significant information and communication technology (ICT) investments, but the empirical evidence of the impact of these investments on business outcomes has been inconsistent. This article studies the conditions that disclosed information resources and ICT must fulfil in order to become a source of sustainable competitive advantage in tourism organizations. The results point to the need to identify distinct financial and non-financial information dimensions, distinguished according to their direct poten…
Asset Tangibility, information asymmetries and intangibles as determinants of family firms leverage
2022
Using a sample of Spanish tourism small and medium-sized firms, we have tested the impact of family control, publicly-available information and tangibility on financial structure, providing a multi-theoretical model that incorporates contributions from the classical theory of finance, inspired by agency theory, the behavioural theory of the firm and strategic theory. The results point to the need to jointly consider the effects of information transmission practices, asset investment decisions and ownership structures on debt capacity. The results show how family control is associated with propensity to take on debt, so that the desire to maintain social control and socioemotional wealth pre…
Speed-dependent line profile: A test of a unified model from the Doppler to the collisional regime for molecule-molecule collisions
2000
International audience; A speed-dependent line profile combining soft and hard fully correlated Dicke-narrowing collisions was recently successfully tested on Ar-broadened H-2 spectra in a wide density and temperature range. A further test for mixtures of H-2 in nitrogen molecules (instead of Ar atoms) is presented. This test is also based on high resolution Raman investigation of the isotropic Q(1) line of H-2 from low to high density at various temperatures. The same consistency of the speed-dependent line profile as for H-2-Ar is obtained for H-2-N-2 through a remarkable agreement with all the data by using a unique set of four parameters (the collisional width and shift, the kinetic fre…
Features of W production in p-p, p-Pb and Pb-Pb collisions
2017
We consider the production of inclusive W bosons in variety of high-energy hadronic collisions: p--p, p--$\overline{\rm p}$, p--Pb, and Pb--Pb. In particular, we focus on the resulting distributions of charged leptons from W decay that can be measured with relatively low backgrounds. The leading-order expressions within the collinearly factorized QCD indicate that the center-of-mass energy dependence at forward/backward rapidities should be well approximated by a simple power law. The scaling exponent is related to the small-$x$ behaviour of the quark distributions, which is largely driven by the parton evolution. An interesting consequence is the simple scaling law for the lepton charge as…
Amor y misoginia. A propósito de "amor fou" de Marta Sanz
2019
En este breve texto abordamos una aproximación a las relaciones amorosas, la misoginia romántica y su vinculación con las relaciones asimétricas de género en sociedades occidentales contemporáneas, a partir del análisis discursivo de la novela Amor Fou de la escritora Marta Sanz (2018). Todo discurso narrativo imaginado es, simultáneamente, producto de la realidad social e histórica en la que se inscribe y productor de las representaciones simbólicas hegemónicas que sustentan relaciones instituidas de desigualdad entre los distintos agentes sociales. Desde esta perspectiva, el análisis que proponemos de esta ficción narrativa se inscribe en el cruce de algunas renovaciones epistemológicas y…
