Comunicació política i estratègia electoral: Xavier Trias i les eleccions municipals del 22 de maig del 2011 a Barcelona

En les eleccions municipals del 22 de maig del 2011 el candidat de CiU es va imposar a les urnes. En el seu tercer intent des del 2003, el veterà polític Xavier Trias aconseguia derrotar el PSC, que controlava l'Ajuntament des de l'any 1979, quan es van celebrar els primers comicis locals de la nova etapa democràtica. Seguint propostes d'anàlisi provinents de la comunicació política i el màrqueting, aquest article indaga les raons de l'èxit del candidat nacionalista: les fortaleses del candidat (diàleg, empatia, experiència), la selecció d'eslògans rellevants i simples («L'alcalde de les persones», «El canvi en positiu» i «Tu&Trias»), una campanya transversal en la qual es va potenciar l'organització de trobades directes amb públics objectius (reunions, col·loquis, dinars), la difusió d'informació a través de periodistes i mitjans de comunicació tradicionals, i una estratègia activa a Internet i les xarxes socials.In the municipal elections of 22 May 2011, the candidate of the Convergence and Union party (CiU) won in the polls. In his third attempt since 2003, Xavier Trias managed to defeat the Catalan Socialist Party (PSC), which had controlled the City Council since 1979 when the first local elections were held in Spain’s new democratic era. Applying analysis proposals based on political communication and marketing, this paper explores the reasons for Trias’s success: his strengths (dialogue, empathy, experience); the use of simple relevant slogans (“The mayor for people”, “Positive change” and, in a play on words in Catalan, “You&Trias”/ “It’s Up to You”), and a transverse campaign focused on personal meetings with target groups through gatherings, discussions and lunches, on the dissemination of information through journalists and traditional communication media, and on an active Internet and social networks strategy

Prototype ATLAS IBL Modules using the FE-I4A Front-End Readout Chip

The ATLAS Collaboration will upgrade its semiconductor pixel tracking detector with a new Insertable B-layer (IBL) between the existing pixel detector and the vacuum pipe of the Large Hadron Collider. The extreme operating conditions at this location have necessitated the development of new radiation hard pixel sensor technologies and a new front-end readout chip, called the FE-I4. Planar pixel sensors and 3D pixel sensors have been investigated to equip this new pixel layer, and prototype modules using the FE-I4A have been fabricated and characterized using 120 GeV pions at the CERN SPS and 4 GeV positrons at DESY, before and after module irradiation. Beam test results are presented, including charge collection efficiency, tracking efficiency and charge sharing.Comment: 45 pages, 30 figures, submitted to JINS

Constraints on the χ_(c1) versus χ_(c2) polarizations in proton-proton collisions at √s = 8 TeV

The polarizations of promptly produced χ_(c1) and χ_(c2) mesons are studied using data collected by the CMS experiment at the LHC, in proton-proton collisions at √s=8  TeV. The χ_c states are reconstructed via their radiative decays χ_c → J/ψγ, with the photons being measured through conversions to e⁺e⁻, which allows the two states to be well resolved. The polarizations are measured in the helicity frame, through the analysis of the χ_(c2) to χ_(c1) yield ratio as a function of the polar or azimuthal angle of the positive muon emitted in the J/ψ → μ⁺μ⁻ decay, in three bins of J/ψ transverse momentum. While no differences are seen between the two states in terms of azimuthal decay angle distributions, they are observed to have significantly different polar anisotropies. The measurement favors a scenario where at least one of the two states is strongly polarized along the helicity quantization axis, in agreement with nonrelativistic quantum chromodynamics predictions. This is the first measurement of significantly polarized quarkonia produced at high transverse momentum

X-ray emission from the Sombrero galaxy: discrete sources

We present a study of discrete X-ray sources in and around the bulge-dominated, massive Sa galaxy, Sombrero (M104), based on new and archival Chandra observations with a total exposure of ~200 ks. With a detection limit of L_X = 1E37 erg/s and a field of view covering a galactocentric radius of ~30 kpc (11.5 arcminute), 383 sources are detected. Cross-correlation with Spitler et al.'s catalogue of Sombrero globular clusters (GCs) identified from HST/ACS observations reveals 41 X-rays sources in GCs, presumably low-mass X-ray binaries (LMXBs). We quantify the differential luminosity functions (LFs) for both the detected GC and field LMXBs, whose power-low indices (~1.1 for the GC-LF and ~1.6 for field-LF) are consistent with previous studies for elliptical galaxies. With precise sky positions of the GCs without a detected X-ray source, we further quantify, through a fluctuation analysis, the GC LF at fainter luminosities down to 1E35 erg/s. The derived index rules out a faint-end slope flatter than 1.1 at a 2 sigma significance, contrary to recent findings in several elliptical galaxies and the bulge of M31. On the other hand, the 2-6 keV unresolved emission places a tight constraint on the field LF, implying a flattened index of ~1.0 below 1E37 erg/s. We also detect 101 sources in the halo of Sombrero. The presence of these sources cannot be interpreted as galactic LMXBs whose spatial distribution empirically follows the starlight. Their number is also higher than the expected number of cosmic AGNs (52+/-11 [1 sigma]) whose surface density is constrained by deep X-ray surveys. We suggest that either the cosmic X-ray background is unusually high in the direction of Sombrero, or a distinct population of X-ray sources is present in the halo of Sombrero.Comment: 11 figures, 5 tables, ApJ in pres
