Klebanov-Witten theory with massive dynamical flavors

We consider the addition of a large number of massive dynamical flavors to the Klebanov-Witten theory, the quiver gauge theory describing the low energy dynamics of Nc D3-branes at the conifold singularity. Massive flavors are introduced by means of Nf D7-branes which are holomorphically embedded and smeared along the transverse directions. After some general comments on the validity of the smearing procedure, we find the full backreacted supergravity solution corresponding to a particular class of massive embeddings. The solution depends on a running effective number of flavors, whose functional form follows from the smeared embedding. The running reflects the integrating in/out of massive degrees of freedom in the dual field theory as the energy scale is changed. We study how the dynamics of the theory depends on the flavor parameters, mainly focusing on the static quark-antiquark potential. As expected, we find that the dynamical flavors tend to screen the static color charges.Comment: 31 pages, 8 figures; v2: few comments and a reference added, minor change

Self/scape: an exploration of belonging and wayfaring

Self/Scape is an autoethnographic sonic exploration of searching, belonging, and praying through sound as well as exploring the socio-cultural conditions and the lived experiences of a globalized Latino. Following the framework of Practice as Research (PaR), Miguel has been creating and theorizing about and through this piece during his two-year degree. This piece is the culmination of Miguel’s research at UCT in which a theatrical production is transformed into a curated space that is made to coexist with(in) a digital soundscape. That is to say that this piece has been created to be experienced through the use of headphones and QR codes. Each QR code will be specifically placed in relation to the content of the code which documents the journey of self-discovery through a multitude of spaces around the world from Los Angeles to Cape Town

Non chiral dynamical flavors and screening on the conifold

We present a new class of string theory solutions which are conjectured to be dual to the N=1 conifold theory by Klebanov and Witten coupled to non chiral massive dynamical flavors. These are introduced, in the Veneziano limit, by means of suitably embedded and smeared D7-branes whose full backreaction on the background is taken into account. The string solutions are used to study chromoelectric charge screening effects due to the dynamical flavors in the non perturbative regime of the dual gauge theories.Comment: 6 pages, 1 figure, previously unpublished results presented.

Proyecto: plan de negocios "The Coffee Workshop Inc. generación de escenarios en base a factores exógenos" / subtítulo.

The Coffee Workshop Inc. is a gourmet coffee shop that offers to their clients the opportunity to experience all the sensations that the coffee can offer. The atmosphere in our shops will try to enhance all the characteristics of the coffee, so our clients will have a complete experience surrounding the coffee. Our main target will be business people, executives that lacking of a conference room in their own companies, are searching for conference halls. Our business rooms will offer all the facilities the executives need, we will offer catering service, and all the IT resources needed for an optimal meeting. Our project is meant to start its operation on January 5th, 2013 and our projections are made for predicting the next five years of sales. We will generate three scenarios based of the fluctuation of the rent payments, the analysis will be created from the industry information, inflation forecast and historical rent prices. These scenarios will try to predict what will happen if we have to pay higher or lower rent payments. This will help us to be more prepared to face all the different incidents that on the operations that can appear

Holographic Flavored Quark-Gluon Plasmas

Holography provides a novel method to study the physics of Quark Gluon Plasmas, complementary to the ordinary field theory and lattice approaches. In this context, we analyze the informations that can be obtained for strongly coupled Plasmas containing dynamical flavors, also in the presence of a finite baryon chemical potential. In particular, we discuss the jet quenching and the hydrodynamic transport coefficients.Comment: 10 pages.
