Abstract

The effects of energy loss in cold nuclear matter on J/psi suppression in p-A collisions are studied. A simple model based on first principles and depending on a single free parameter is able to reproduce J/psi suppression data at large xF and at various center-of-mass energies. These results strongly support energy loss as a dominant effect in quarkonium suppression. They also give some hint on its hadroproduction mechanism suggesting color neutralization to happen on long time-scales. Predictions for J/psi and Upsilon suppression in p-Pb collisions at the LHC are made., Comment: 4 pages, 4 figures

Abstract

The postcranial skeleton of the European Middle Miocene feline Styriofelis lorteti has been traditionally known on the basis of fragmentary fossils mainly from the French locality of Sansan. The discovery of an almost complete skeleton in the same site in the excavations of 1990 opened the possibility of unprecedented assessment of the morphology and function of this early felid. In this paper we describe this material, and compare it with a sample of modern and fossil felids, finding a combination of a generally modern morphology, with moderate adaptations to terrestrial locomotion, besides a set of primitive characters linking S. lorteti with earlier felids like Proailurus lemanensis.El esqueleto post-craneal del felino Styriofelis lorteti, del Mioceno medio de Europa, ha sido tradicionalmente conocido en base a fósiles fragmentarios, procedentes principalmente del yacimiento francés de Sansan. El descubrimiento en este yacimiento de un esqueleto casi completo, durante la campaña de 1990, abrió la posibilidad de llevar a cabo un análisis sin precedentes de la morfología y función de este félido primitivo. En este trabajo se describe este material, comparándose con una muestra de felinos fósiles y actuales, hallándose una combinación entre una morfología general moderna, con adaptaciones moderadas para la locomoción terrestre, junto con una serie de caracteres primitivos que relacionan a S. lorteti con los félidos más antiguos como Proailurus lemanensis.
