No full textHeavy meson production in hot dense matter
No full textThe properties of charmed mesons in dense matter are studied using a unitary coupled-channel approach in the nuclear medium which takes into account Pauli-blocking effects and meson self-energies in a self-consistent manner. We obtain the open-charm meson spectral functions in this dense nuclear environment, and discuss their implications on hidden charm and charm scalar resonances and on the formation of D-mesic nuclei at FAIR energies.</p
The contribution of the Basque men to the Philippines
No full textEl director de la Biblioteca Nacional de Filipinas, Eulogio B. Rodríguez, señala que muchos apellidos filipinos son de origen vasco; en la época de dominio colonial español, la mayor parte de los oficiales de la marina eran vascos y una provincia del país se llama Nueva Vizcaya. Cita varios vascos que tuvieron una intervención importante en la historia de las islas filipinas: Miguel López de Legazpi, personaje principal en la colonización; los gobernadores Simón de Anda y Salazar, Guido de Lavezares y Gabriel de Curuzeleagui y Arriola; o el franciscano Melchor Oyanguren, autor de textos religiosos.Filipinar deitura asko euskal jatorrikoak direla azaltzen digu Eulogio B. Rodríguez, Filipinetako Liburutegi Nazionaleko zuzendariak. Espainia nagusi zeneko aro kolonialean, itsas armadako ofizial gehienak euskaldunak ziren, eta herrialdeko probintzia batek Nueva Vizcaya du izena. Filipinar uharteetako historian partaidetza garrantzitsua izan zuten zenbait euskaldun aipatzen du: Miguel López de Legazpi, kolonizazioko pertsonaia nagusia; Simón de Anda y Salazar, Guido de Lavezares eta Gabriel de Curuzeleagui y Arriola gobernariak; edo Melchor Oyanguren frantziskotarra, erlijiozko testu batzuen egilea.Le Directeur de la Bibliothèque Nationale des Philippines Eulogio B. Rodríguez indique que beaucoup de noms aux Philippines sont d'origine basque; à l'époque espagnole, la plupart des officiers de marine étaient Basques et une province des Philippines s'appelle Nueva Vizcaya. Il cite plusieurs Basques importants dans l'histoire des Iles Philippines: Miguel López de Legazpi, personnage notable de la colonisation; les gouverneurs Simón de Anda y Salazar, Guido de Lavezares et Gabriel de Curuzeleagui y Arriola; en fin, le Père Melchor Oyanguren, franciscain et auteur religieux.The director of the National Philippines Library, Eulogio B. Rodríguez, indicates that many Philippine surnames are of Basque origin; in the era of Spanish colonial dominance, most navy officers were Basque and one of the provinces in the country is called New Biscay. The author then quotes several Basques who played an important role in the history of the Philippine islands: Miguel López of Legazpi, one of the main characters during the coloniliasation; Governor Simón de Anda y Salazar, Guido de Lavezares and Gabriel de Curuzeleagui y Arriola; or the Franciscan monk Melchor Oyanguren, who was the author of important religious texts
On the ambiguities of sign determination of the S-matrix from energy levels in a finite box
No full textIn a recent paper the authors make a study on the determination of the S-matrix elements for scattering of particles in the infinite volume from the energy levels in a finite box for the case of multiple channels. The study is done with a toy model in 1+1 dimension and the authors find that there is some ambiguity in the sign of nondiagonal matrix elements, casting doubts on whether the needed observables in the infinite volume can be obtained from the energy levels of the box. In this paper I present an easy derivation, confirming the ambiguity of the sign and argue that this, however, does not put restrictions in the determination of observables.The author would like to thank T.

Transparency ratio in γ A -> η' A ' and the in-medium η ' width
No full textThe photoproduction of η′η′-mesons off different nuclei has been measured with the CBELSA/TAPS detector system for incident photon energies between 1500-2200 MeV. The transparency ratio has been deduced and compared to theoretical calculations describing the propagation of η′η′-mesons in nuclei. The comparison indicates a width of the η′η′-meson of the order of Γ=15-25 MeVΓ=15-25 MeV at ρ=ρ0ρ=ρ0 for an average momentum pη′=1050 MeV/cpη′=1050 MeV/c, at which the η′η′-meson is produced in the nuclear rest frame. The inelastic η′Nη′N cross section is estimated to be 3-10 mb. Parameterizing the photoproduction cross section of η′η′-mesons by σ(A)=σ0Aασ(A)=σ0Aα, a value of α=0.84±0.03α=0.84±0.03 has been deduced.M. Nanova1, V. Metag1, A. Ramos2, E. Oset3, I. Jaegle4,a, K.

La prosa del arte mozárabe: algunos apuntes sobre S. Eulogio
No full textThe present paper aims at a study of the Latin as used by writers from Córdoba in the 9th ccntury. To this end, we propose an analysis of some lexical and stylistic features of St. Eulogius’ works, as the language of this particular author has received scant attention up to the present.El presente trabajo contribuye al estudio sobre el latín de los escritores cordobeses del s. IX. Con ese fin se analizan algunos aspectos léxicos y estilísticos de la obra de S. Eulogio, ya que la lengua de este importante autor apenas ha recibido atención hasta este momento
