La Ventilla

The research presented here confronts the issue of ritual variation and its role in structuring the social dynamics of ancient Teotihuacan, a state that dominated central Mexico during the first half-millennium A.D. Most of Teotihuacan's urban population lived in apartment compounds located across the city, but the nature of these co-residing groups is not well understood. Even less is known about how subordinate settlements beyond the city limits were organized and to what degree they identified socially with urban Teotihuacan. Because ritual practices are salient in the negotiation of social identities related to gender, age, ethnicity, social status, and religious affiliation, they are an important focus of archaeological research.

RESUMEN Este artículo nació con un deseo, y es hablar de arquitectura de la antigua ciudad de Teotihuacan (México), sin que se omita la labor de los gremios de albañiles que la hicieron posible y cuyas actividades no han figurado dentro de las preocupaciones académicas de los especialistas de esta metrópoli precolombina. Por ello, en el marco de las exploraciones arqueológicas realizadas dentro del barrio teotihuacano de La Ventilla y particularmente del hallazgo de enigmáticos patrones de fosas sobre sus suelos, es que realizamos ejercicios de arqueología experimental con el fin de aproximarnos a algunas operaciones, técnicas y soluciones ingenieriles que cotidianamente realizaban estos albañiles como parte de su subsistencia básica., Un intento por dimensionar la relevancia técnica e importancia social de estos gremios en el universo de la arquitectura antigua. ABSTRACT This article was born with a desire, and talk about architecture of the ancient city of Teotihuacan (Mexico), without the guilds of stonemasons who made it possible and whose activities have not figured within the academic concerns of specialists and this pre-Columbian metropolis. Therefore, as part of archaeological explorations in the Teotihuacan neighborhood of La Ventilla and particularly the discovery of enigmatic patterns of pits on their floors, is that we do exercises of experimental archeology in order to approach some operations, techniques and engineering solutions that routinely performing these builders as part of their basic subsistence., an attempt to scale their technical relevance and social importance of these associations in the universe of ancient architecture.

The ALICE experiment has measured the inclusive J/ψ production in Pb-Pb collisions at √ s NN = 2.76 TeV down to zero transverse momentum in the rapidity range 2.5 < y < 4. A suppression of the inclusive J/ψ yield in Pb-Pb is observed with respect to the one measured in pp collisions scaled by the number of binary nucleon-nucleon collisions. The nuclear modification factor, integrated over the 0%-80% most central collisions, is 0.545 ± 0.032(stat.) ± 0.083(syst.) and does not exhibit a significant dependence on the collision centrality. These features appear significantly different from measurements at lower collision energies. Models including J/ψ production from charm quarks in a deconfined partonic phase can describe our data. * See Appendix A for the list of collaboration members J/ψ suppression at forward rapidity in Pb-Pb collisions at √ s NN = 2.76 TeV 1
