A New Parametrization Of Mass Varying Neutrinos Applied In Supernovae
No full textWe propose a phenomenological model of mass varying neutrino (MaVaN) to be applied to supernovae. We consider oscillations of . νV e→νV s in this MaVaN approach and seek for possible modifications of survival probabilities. © 2012 Elsevier B.V.229-232557Fardon, R., Nelson, A.E., Weiner, N., (2004) JCAP, 410, p. 005. , arxiv:astro-ph/0309800Kaplan, D.B., Nelson, A.E., Weiner, N., (2004) Phys.

Solar Mhd Waves And Solar Neutrinos
No full textWe analyze here how solar neutrino experiments could detect time fluctuations of the solar neutrino flux due to magnetohydrodynamics (MHD) perturbations of the solar plasma. We state that if such time fluctuations are detected, this would provide a unique signature of the Resonant Spin-Flavor Precession (RSFP) mechanism as a solution to the Solar Neutrino Problem.10701/02/158997Abdurashitov, D.N., (2001) Nucl.Phys.

Dissipation And θ 13 In Neutrino Oscillations
No full textWe obtain a complete survival and transition probability involving three neutrino flavors when dissipation effects in vacuum are taken into consideration. In an approach that presents decoherence and relaxation effects, we study the behavior of the probabilities obtained from complete positivity constraints. Making the von Neumann entropy increase in time, many cases can be obtained and studied with the Lindblad master equation with addition of only one or two parameters related to dissipation. New possibilities are obtained when we take into account two decoherence parameters with different magnitudes which are given by reactor and accelerator neutrino oscillation experiments. We also present a model with only one parameter that has an important symmetry property, which can be used when the effective matter potential is important. Furthermore, the dissipation effects can contribute to the appearance of neutrinos that can hide or imitate the θ 13 effects and we study these possibilities showing that dissipative effects have an important role in three-neutrino oscillations. © 2013 Springer-Verlag Berlin Heidelberg and Società Italiana di Fisica.735110Gago, A.M., (2002), arXiv: hep-ph/0208166Barenboim, G., Mavromato, N.E., (2005) J.

Updated Solution To The Solar Neutrino Problem Based On Non-standard Neutrino Interactions
No full textWe present an updated version of the solution to the solar neutrino problem based on non-standard flavor changing neutrino interactions (FCNI) and non-universal flavor diagonal neutrino interactions (FDNI). We find a good fit not only to the total rates measured by all solar neutrino experiments but also to the day-night and seasonal variations of the event rate, as well as the recoil electron energy spectrum measured by the SuperKamiokande collaboration. © 2001 Elsevier Science B.V.1001-36264Bergmann, S., Guzzo, M.M., De Holanda, P.C., Krastev, P.I., Nunokawa, H., (2000) Phys.

Simulation Of Double-bang Event Induced By Neutrino In The Atmosphere
No full textWe use CORSIKA+Herwig simulation code to produce ultra-high energy neutrino interactions in the atmosphere. Our aimis to reproduce extensive air showers originated by extragalactic tau-neutrinos. For charged current tau-neutrino interactions in the atmosphere, beside the air shower originated from the neutrino interaction it is expected that a tau is created and may decay before reaching the ground. That phenomenon makes possible the generation of two extensive air showers, the so called Double- Bang event. We make a quantitative analysis of the main characteristics of Double-Bang events in the atmosphere and conclude that it may be possible to observe this kind of event in ultra-high energy cosmic ray observatories such as Pierre Auger.5HE PART 213811384Sokolsky, P., (2004) Introduction to Ultrahigh Energy Cosmic Ray Physics, , Westview PressGaisser, T.K., (1990) Cosmic Rays and Particle Physics, , Cambridge University Press, UKYamamoto, T., Mase, K., Takeda, M., Sakaki, N., Teshima, M., Signatures of ultrahigh energy cosmic ray composition from propagation of nuclei in intergalactic photon fields (2004) Astropart.

Authority and Personality in M.M. Bakhtin\u27s Author and Hero in Aesthetic Activity
No full textM.M. Bakhtin\u27s fundamental claim in his seminal essay Author and Hero in Aesthetic Activity situates verbal action as the most essential constituent of human personality. A careful reading of this text reveals important truths about the relationship between free individual personhood and the nature of the speech utterance. Bakhtin connects the human experience of speech to the life and person of Jesus Christ emphasizing the incarnation and the Trinitarian view of God as essential principles for understanding the creative power of the word and consequent liabilities. Bakhtin develops these theological and philosophical coordinates around a discussion of the author-hero relationship in the novel asserting that the verbal utterance is creatively involved in building and sustaining the inner personhood of those it addresses. Bakhtin\u27s critical conclusion substantiates that from whom a word is received, and to whom the spoken word appeals has weighty influence on the type and character of human personality, and that personality\u27s relationship to authority
