Maximum Entropy Inferences on the Axion Mass in Models with Axion-Neutrino Interaction

In this work we use the Maximum Entropy Principle (MEP) to infer the mass of an axion which interacts to photons and neutrinos in an effective low energy theory. The Shannon entropy function to be maximized is suitably defined in terms of the axion branching ratios. We show that MEP strongly constrains the axion mass taking into account the current experimental bounds on the neutrinos masses. Assuming that the axion is massive enough to decay into all the three neutrinos and that MEP fixes all the free parameters of the model, the inferred axion mass is in the interval $0.1\$eV$\ <m_{A}<0.2$ eV, which can be tested by forthcoming experiments such as IAXO. However, even in the case where MEP fixes just the axion mass and no other parameter, we found that $0.1$ eV $< m_A < 6.3$ eV in the DFSZ model with right-handed neutrinos. Moreover, a light axion, allowed to decay to photons and the lightest neutrino only, is determined by MEP as a viable dark matter candidate.Comment: 13 pages, 5 figures, typos corrected, figures update

Inferences on the Higgs Boson and Axion Masses through a Maximum Entropy Principle

The Maximum Entropy Principle (MEP) is a method that can be used to infer the value of an unknown quantity in a set of probability functions. In this work we review two applications of MEP: one giving a precise inference of the Higgs boson mass value; and the other one allowing to infer the mass of the axion. In particular, for the axion we assume that it has a decay channel into pairs of neutrinos, in addition to the decay into two photons. The Shannon entropy associated to an initial ensemble of axions decaying into photons and neutrinos is then built for maximization.Comment: Contributed to the 13th Patras Workshop on Axions, WIMPs and WISPs, Thessaloniki, May 15 to 19, 201

Fronteras del deseo: melodrama y crítica social en "Tengo miedo torero", de Pedro Lemebel

este artículo investiga la novela Tengo miedo torero (2001), del escritor chileno Pedro Lemebel, y su objetivo es demostrar que la narrativa de dicha obra despliega un discurso crítico en torno a la historia chilena bajo la dictadura militar - hecho que le confiere un carácter de metaficción historiográfica (Hutcheon, 1991)-, relacionándolo, además, con artificios temáticos y formales del género melodramático, lo cual crea en esa ficción un espacio discursivo híbrido para el reconocimiento y el abrigo de lenguajes y comportamientos no instituidos por el tejido social, que ahí logran ser aceptados como subjetivos y legítimos (Agamben, 2008). La performance del personaje protagonista de la narrativa y su condición de frontera en cuanto al género y otras cuestiones vinculadas con las minorías sociales, forman algunas de las cuestiones que la novela despliega y que conducen las representaciones del deseo de libertad (Bauman, 1998) que sostienen el eje principal de la obra literaria de Lemebel.this article analyzes the novel Tengo miedo torero (2001), by Chilean writer Pedro Lemebel. The study aims to demonstrate how that narrative develops a critic discourse about the Chilean history under military dictatorship's power. The Lemebel's text can be described as a historiographic metafiction (Hutcheon, 1991). The textual construction, in this novel, is associate with the melodramatic genre, and its writing procedures create a hybrid discursive space where the literary enunciation acknowledges discourses and languages that hasn't generally been institutionalized by social structures. These constructive aspects contribute for the protagonist character's subjectivity (Agamben, 2008), an effeminate gay man that is representative character of a social condition characterized by borders and risks. In this novel, then, the performance made by the protagonist shows and promotes some discussions about the (homo)sexual desire, the individual and collective freedom (Bauman, 1998) and the representations of certain minority groups in Latin American Contemporary Literature
