| dc.description | En el presente trabajo se expone un modelo para producci´on de materia oscura escalar a partir de neutrinos pesados de Majorana por medio del mecanismo de freeze-in. Estos neutrinos forman parte del modelo est´andar m´ınimamente extendido, cuya diferencia principal con el modelo esta´ndar es que incluye neutrinos derechos. El acoplamiento entre las part´ıculas de materia oscura y dichos neutrinos es de tipo Yukawa. La herramienta principal para la produccio´n de materia oscura es la ecuacio´n de Boltzmann, por medio de esta se halla el nu´mero de part´ıculas en funcio´n del cociente entre la masa de los neutrinos pesados de Majorana y la temperatura del universo. En particular, se encontraron cotas para la masa de la materia oscura y su acoplamiento con los neutrinos derechos. Adem´as, se mostro´ la viabilidad del modelo para la produccio´n de materia oscura a partir de neutrinos pesados. | es_CO |
| dc.description.abstract | In the present work, a model for the production of scalar dark matter from heavy Majorana neutrinos by means of the freeze-in mechanism is exposed. These neutrinos are part of the minimally extended standard model, whose main difference from the standard model is that it includes straight neutrinos. The coupling between the dark matter particles and these neutrinos is of the Yukawa type. The main tool for the production of dark matter is the Boltzmann equation, through which the number of particles is found as a function of the quotient between the mass of Majorana’s heavy neutrinos and the temperature of the universe. In particular, bounds were found for the mass of dark matter and its coupling with the right neutrinos. In addition, the feasibility of the model for the production of dark matter from heavy neutrinos was shown. | es_CO |
