    Description: Author(s): L. J. Flores, E. A. Garcés, and O. G. Miranda One of the main purposes of long-baseline neutrino experiments is to unambiguously measure the C P violating phase in the neutrino sector within the three neutrino oscillation picture. In the presence of physics beyond the Standard Model, the determination of the C P phase will be more difficult, due ... [Phys. Rev. D 98, 035030] Published Tue Aug 21, 2018

    Description: Author(s): R. Martinez, R. Gaitán, J. H. Montes de Oca, and E. A. Garcés We compute the contributions to rare top decays t → c Z and t → c h 1 from the scalar sector in the two Higgs doublet model type III with C P violation, where h 1 is the Standard Model Higgs boson. The branching ratios for BR ( t → c Z ) and BR ( t → c h 1 ) are obtained as a function of the model parameters. In particul... [Phys. Rev. D 98, 035031] Published Tue Aug 21, 2018

    Description: El cangrejo de tierra Cardisoma guanhumi, (Latreille, 1825) habita en el Parque Nacional Ciénaga de Zapata y constituye un recurso de importancia comercial. Se determinó la densidad media de la población de C. guanhumi en las zonas de captura Guamutal, El Maíz, La Arenera y Bolanio. Se utilizó un método de estimación indirecta y se muestrearon 11 parcelas de 81 m2 en febrero/2013 para un área total de 748 m2; además, se realizaron muestreos mensuales durante la temporada de captura (mayo, junio y julio del 2013). La densidad media de cuevas varió de 0,52 a 2,23 cuevas/m2, con una media de 1,43 cuevas/m2. La zona de mayor densidad fue La Arenera con 1,81 cuevas/m2 y la menor Bolanio con 0,52 cuevas/m2. El diámetro promedio de las cuevas fue de 10,13 ± 0,34 cm, 7,74 ± 0,56 cm y 5,59 ± 0,30 cm en El Maíz, La Arenera y Guamutal respectivamente. Se observaron diferencias significativas entre los diámetros medios. Los valores de menor diámetro en Guamutal refuerzan la hipótesis de que ésta constituye una zona de reclutamiento. La talla media del cangrejo disminuye a medida que trascurre la corrida. La captura posee un esquema de “Libre Acceso” y por ello se considera al cangrejo explotado intensamente, con disminución de la talla media de captura e incremento de ejemplares por debajo de la talla mínima legal. La presencia de cangrejos está asociada a los mangles Laguncularia racemosa y Conocarpus erectus. La fauna asociada a C. guanhumi la constituyen cangrejos ermitaños (Eupagurus sp.), cocodrilos (Crocodylus rhombifer) y perros jíbaros (Canis familiares).
    Description: At the National Park, Cienaga de Zapata inhabits the land crab (Cardisoma guanhumi, Lattreille, 1825) constituting a resource of commercial importance. To determinate the average density of the population in the catchment areas Guamutal, El Maiz and La Arenera, it was used an indirect method; it were sampled 11 locations with 81 m2 at febrary/2013 for a total area of 748 m2. Also there were done monthly samples to the capture during the capture season. The caves average density varied from 0,52 to 2,23 caves/m2, with an overall average of 1,43 caves/m2. The area most densely populated was La Arenera with 1,81 caves/m2 and the lower was Bolanio with 0,52 caves/m2. The average diameter of the caves was 10,3±0,34cm, 7,74±0,56cm and 5,59±0,30cm in El Maiz, La Arenera and Guamutal respectively. There is significant difference between the mean diameters. The presence of small diameters caves in Guamutal reinforces the hypothesis that this is the main area of recruitment. The crab average size decrease along the capture season. His capture has a “Free Access” scheme and crab is considered as intensely exploited. The percentage of specimens below the legal minimum size has been increased and therefor the average size has decreased. The crab presence is associated with gender mangrove, Laguncularia racemosa and Conocarpus erectus. In the fauna associated with C. guanhumi there were observed the hermit crabs (Eupagurus sp.), crocodiles (Crocodylus rhombifer) and wild dogs (Canis familiares).
