Evidence for the decay B0→J/ψω and measurement of the relative branching fractions of meson decays to J/ψη and J/ψη′
No full textFirst evidence of the B 0 → J / ψ ω decay is found and the B s 0 → J / ψ η and B s 0 → J / ψ η ′ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 fb -1 collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV. The branching fractions of these decays are measured relative to that of the B 0 → J / ψ ρ 0 decay:frac(B (B 0 → J / ψ ω), B (B 0 → J / ψ ρ 0)) = 0.89 ± 0.19 (stat) - 0.13 + 0.07 (syst),frac(B (B s 0 → J / ψ η), B (B 0 → J / ψ ρ 0)) = 14.0 ± 1.2 (stat) - 1.5 + 1.1 (syst) - 1.0 + 1.1 (frac(f d, f s)),frac(B (B s 0 → J / ψ η ′), B (B 0 → J / ψ ρ 0)) = 12.7 ± 1.1 (stat) - 1.3 + 0.5 (syst) - 0.9 + 1.0 (frac(f d, f s)), where the last uncertainty is due to the knowledge of f d / f s, the ratio of b-quark hadronization factors that accounts for the different production rate of B 0 and B s 0 mesons. The ratio of the branching fractions of B s 0 → J / ψ η ′ and B s 0 → J / ψ η decays is measured to befrac(B (B s 0 → J / ψ η ′), B (B s 0 → J / ψ η)) = 0.90 ± 0.09 (stat) - 0.02 + 0.06 (syst)

Pagaburo, Col. 21/04/1999.</p> <p> <b>Etymology.</b> Pacha comes from the Aimara and Quechua indigenous languages from northwestern Argentina. It means “earth” and by extension “world” or “cosmos”. In this part of the country, social gatherings called Pachamama are celebrated every year in the autumn to thank and bless the earth and its products.</p> <p> <b>Diagnosis.</b> <i>Liolaemus pacha</i> <b>sp. nov.</b>, belongs to the <i>L. boulengeri</i> group because it has a patch of enlarged scales on the posterior region of the thigh (Etheridge 1995; Abdala <i>et al.</i> 2006). Within this group, it belongs to the <i>L. laurenti</i> group (Abdala 2007) because its posterior teeth have straight edged crowns and sexual dichromatism is evident. Within the <i>L. laurenti</i> group, <i>Liolaemus pacha</i> sp nov. is a member of the <i>L. darwinii</i> group (Abdala 2007) or the <i>darwinii</i> complex (Etheridge 1993) because it has a black line which crosses the eye vertically (except <i>L. chacoensis</i>) and pre-scapular spots in both males and females (Abdala 2007). Within the <i>L. darwinii</i> group (Abdala 2007), <i>L. pacha</i> differs from the members of the <i>L. ornatus</i> group (<i>L. albiceps, L. calchaqui, L. crepuscularis, L. irregularis, L. lavillai</i>, and <i>L. ornatus</i>) because it has an oviparous reproductive mode. It also differs from <i>L. albiceps</i> and <i>L. irregularis</i> because it is smaller (max SVL 67.9 mm vs 82.5 and 86.1 mm, respectively). <i>Liolaemus pacha</i> differs from <i>L. abaucan</i> and <i>L. uspallatensis</i> in having imbricate and keeled dorsal scales, whereas in those two species the dorsal scales are smooth or weakly keeled. <i>Liolaemus chacoensis</i> exhibits keeled temporal scales and mucronate dorsal scales, absent in <i>L. pacha</i>. The presence of a large prescapular spot distinguishes <i>L. pacha</i> from <i>L. abaucan</i>, <i>L. darwinii</i> and <i>L. koslowskyi</i>, which have large and evident postscapular spots. It differs from <i>L.</i></p> <p> <i>cinereus</i> in having a black stripe in the lateral field and in lacking melanism on the throat. <i>Liolaemus darwinii</i>, <i>L. grosseorum, L. laurenti, L. montanezi</i> and <i>L. olongasta</i> have a black antehumeral arch, absent in <i>L. pacha</i>.</p> <p> <i>Liolaemus pacha</i> <b>sp. nov.</b> differs from <i>L. quilmes</i> mainly because of its size (see below). It has a larger prescapular spot (Fig. 5, left) than <i>L. quilmes</i> (Fig. 6, left) and numerous light blue scales on the sides of the body and tail (Fig. 2). It has a Y-shaped mark on the snout (Fig. 7), reduced in <i>L. quilmes</i> (Table 1). In <i>L. pacha</i>, scales on dorsum are uniformly colored (Fig. 8) whereas in <i>L. quilmes</i> scales on dorsum are irregularly variegated with diffuse spots (Fig. 9). Both species present alternating light and dark spots on supra and infralabials, more diffuse on infralabials in <i>L. pacha</i> <b>sp. nov.</b> (Fig. 10, top), well marked in <i>L. quilmes</i> (Fig. 10, bottom). Anterior limbs with lightly visible bands and posterior limbs without these (Fig. 2 and 5, left), whereas in <i>L. quilmes</i> both anterior and posterior limbs with visible bands (Fig. 6, left). The new species presents yellow dorsolateral spotted bands (Fig. 2), different from <i>L. quilmes</i> which are continuous. <i>Liolaemus pacha</i> <b>sp. nov.</b> has ventrally scattered spots in the jaw area, light yellow on the throat and thigh areas (Fig. 3 and 5, right), in <i>L. quilmes</i> throat with spots that reach to the neck, ventral area white (Fig. 6, right, Table 1).</p> <p> Moreover, among its distinctive characteristics, <i>L. pacha</i> <b>sp. nov.</b> differs significantly from 3 populations of <i>L. quilmes</i> in 10 characters (Table 2, P <0.05, shown with asterisk): greater snout-vent-lengths in both males and females; higher, wider and longer head in males; larger and wider male torso; longer hand; more scales on average around the body; more gular scales. The new species differs in four other characters (Table 2, P <0.05, shown without asterisk) from one or two of these populations: in two cases, it differed from El Tio y Las Ruinas de Quilmes but not from Animaná (ventral scales, length of female torso); in one case, it differed from Animaná and El Tio but not from Ruinas de Quilmes (length of humerus); and lastly, it differed from Animaná but not from El Tío and Ruinas de Quilmes (head width of females).</p> <p> <b>Description of the holotype.</b> Adult male.

The type locality is characterized by firm substrate, large rocks, scattered shrubs and tall cacti (<i>Thrichocereus pasacana</i>, Cactaceae). It corresponds to the Monte and Prepuna ecoregions (Cabrera & Willink 1980 <b>)</b>. They are mainly insectivorous occasionally eating small plant parts depending on the season and availability (Halloy <i>et al</i>. 2006). It is an oviparous species (Ramirez Pinilla 1992). Males defend territories which generally overlap with two to three females (Halloy 1996; Halloy & Robles 2002; Robles & Halloy 2009; Robles 2010). Both males and females use visual displays, such as headbobs, forelimb waves, and tail movement, during encounters as well as during courtship (Halloy 1996; Martins <i>et al.</i> 2004; Halloy & Castillo 2006; Halloy 2012).</p> <p> It is a dimorphic species (Etheridge 1993; Halloy 1996; this study), males being slightly larger and more colorful than females. Females present during the reproductive season nuptial coloration on the side of the neck, going from yellowish to intense orange (Halloy <i>et al.</i> 2007; Salica 2008; Salica & Halloy 2009b). Males emerge from hibernation in September whereas females emerge one to two months later (Halloy & Robles 2003). Matings occur end of October, beginning of November. Neonates are observed by the end of December and in January (Ramírez Pinilla 1992; pers. obs.). Males and females remain active through March and April when they return to hibernation.</p>Published as part of <i>Heredia, Viviana Juárez, Robles, Cecilia & Halloy, Monique, 2013, A new species of Liolaemus from the darwinii group (Iguania: Liolaemidae), Tucumán province, Argentina, pp. 524-538 in Zootaxa 3681 (5)</i> on pages 526-533, DOI: 10.11646/zootaxa.3681.5.2, <a href="http://zenodo.org/record/217441">http://zenodo.org/record/217441</a>

El emplazamiento de Canata y la fundación de la villa de Oropesa: Una contribución a la geografía histórica del valle de Cochabamba (Bolivia) en los siglos XV y XVI
No full textHasta la fundación de la villa de Oropesa (hoy ciudad de Cochabamba, Bolivia) en 1571, el centro político, social y económico en el fértil valle de Cochabamba, ya desde tiempos prehispánicos, estaba en “Canata”, localidad mencionada en los documentos españoles más antiguos pero cuyo emplazamiento exacto ha eludido hasta ahora a los investigadores. En el presente artículo deseamos dar a conocer los resultados de un análisis de una documentación nueva de archivo sobre la geografía humana del valle en el siglo XVI; la cual, cotejada con la evidencia arqueológica y topográfica de la zona acumulada desde la década de 1950 para el periodo inca, permite apuntar con unas mínimas garantías hacia la precisa ubicación de Canata en el extremo oriental del valle, resolviendo de paso el problema de la relación de este asentamiento con la posterior fundación de Oropesa.La investigación de Juan J. R. Villarías-Robles es un resultado del proyecto de investigación financiado por el Gobierno español PB 89-0051, "Discursos etnográficos y contextos histórico-sociales ...

Measurement of the time-dependent CP asymmetry in B0 -> J/ψ KS0 decays
No full textThis Letter reports a measurement of the CP violation observables SJ/ψK0S and CJ/ψK0S in the decay channel B0→J/ψK0S performed with 1.0 fb−1 of pp collisions at s√=7 TeV collected by the LHCb experiment. The fit to the data yields SJ/ψK0S=0.73±0.07(stat)±0.04(syst) and CJ/ψK0S=0.03±0.09(stat)±0.01(syst). Both values are consistent with the current world averages and within
expectations from the Standard Model
