Neutriinojen ja kvarkkien sekoitusmatriisien välinen yhteys

2012

In this thesis relations between neutrino mixing matrix and quark mixing matrix are studied. The focus of the analysis is on two simple cases. In the first case it is assumed that the left matrix that diagonalizes the mass matrix of charged leptons and the corresponding matrix of down quarks are equal. In the second case it is likewise assumed that the corresponding diagonalizing matrices of neutrinos and up quarks are equal. First, theoretical concepts related to the mixing of quarks and especially to the mixing of neutrinos are presented. These are e.g. fermion mass generation in the Standard Model, Majorana masses of neutrinos and the so-called seesaw mechanism. Regarding experiments, ne…

La desintegración doble beta sin neutrinos es un proceso hipotético en el que dos neutrones de un núcleo se transforman en dos protones emitiendo únicamente dos electrones, sin neutrinos. La detección de un proceso así demostraría que los neutrinos son partículas de Majorana y que el número leptónico total no se conserva (las oscilaciones de neutrinos ya han demostrado que el número leptónico por familia no se conserva). La determinación de la naturaleza del neutrino podría responder a varias preguntas de diversa índole dentro de la física de partículas. Primero, podría dar explicación a la escala de masas del neutrino a través de un mecanismo de balancín (see-saw). Por…

Within each breath, a large diversity of volatiles molecules of the surrounding reaches our olfactory receptors. Despite the chemical complexity of the natural environment, the organisms succeed to represent their world using relevant information carried by single odorants or mixtures. Focusing on the perception of these stimuli, we explored the processes involved in the treatment of this complex information, sometimes supported by mixtures or sub-mixtures. The treatment is based on two processes: the elemental mode, which allows extracting the odor quality of all or some of the elements, or the configural mode which allows the holistic representation of the mixture. In this doctoral thesis…

International audience; A functional sense of smell is essential for evaluating and enjoying food, receiving information about conspecifics, and detecting threats via airborne chemical cues. Olfactory dysfunction has been associated with an impaired quality of life, reflected by a higher incidence of undesirable mental states such as depression and social insecurity. Addressing and overcoming related olfactory dysfunction issues require a detailed understanding of peripheral and central processes involved in olfaction. Consequently, there is a growing body of research unravelling molecular and cellular interactions that shape olfactory sensation. Recent studies have demonstrated that in the…
