Estrategias asociadas al concepto de publicidad popular en las plazas de mercado de la ciudad de Bogotá Colombia/ Estratégias associadas com o conceito de publicidade popular nos mercados da cidade de Bogotá Colômbia

En el proyecto Publicidad Popular en Plazas de Mercado, se describen las estrategias de publicidad popular identificadas en cuatro plazas de mercado de la ciudad de Bogotá: Quirigua, Fontibón, 20 de Julio y 7 de Agosto, en donde se evidencian las relaciones existentes entre la estética visual y la cultura popular, exteriorizada en costumbres, estilos, y situaciones de vida, que hacen que empíricamente, se desarrollen procesos comunicativos, ligados a la tradición familiar. En este proyecto se encuentran patrones de ruptura y continuidad, que sí bien responden a una manifestación del folklore demosófico, son dinámicas que posibilitan la generación de narrativas y relatos publicitarios que pueden aparecer por mera intuición o como resultado de una estrategia

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
