description Neutrinos are still an intriguing matter in physics due to their odd properties, nevertheless there is a rising field on Neutrino Geoscience using their unique properties to study the Earth. This project shows the results of the simulations done in order to calculate the expected geoneutrino (electron antineutrinos from natural beta decay) signal from different mantle distributions of Heat Producing Elements and Bulk Silicate Earth models. The probability of detecting a geoneutrino is called survival probability. The average two-flavor survival probabilities and an exact approach to matter-oscillations are used. Overall, the two-flavor case shows a good fit to other studies on signal prediction from the mantle but underestimates the total flux from the Earth, while the exact-solution approach overestimates the mantle signal and gives total-flux results within the limits of the observed geoneutrino fluxes provided by KamLAND and Borexino detectors. In spite of that, further testing on the software written for the exact-solution are to be performed to evaluate the implementation accuracy. So far, geoneutrinos have proven to be an useful tool to understand the chemical composition of the planet. However, the resolution of the detectors is a significant limitation; improvements in this matter are expected in the years to come

No obstante, ha surgido un campo en Geociencia de Neutrinos, el cual usa estas propiedades únicas para estudiar la Tierra. En este proyecto se muestran los resultados de las simulaciones hechas para calcular la señal esperada de geoneutrinos (antineutrinos electrónicos provenientes de decaimiento beta natural) para distintas distribuciones de Elementos Productores de Calor (HPE) en el manto, así como diferentes modelos de Composición del Manto Primitivo (BSE). Se denomina probabilidad de supervivencia a la probabilidad de detectar un geoneutrino; para calcularla se utilizó la aproximación de dos sabores y una solución exacta para la oscilación en la materia. En general, el primer caso se ajusta a las predicciones de otros estudios para la señal del manto pero los resultados para el flujo de toda la Tierra son menores de lo esperado; mientras el segundo caso resulta en valores altos para la señal del manto y otorga, para el flujo total, resultados dentro de los límites dados por las observaciones de los detectores KamLAND y Borexino. A pesar de esto, son necesarias más pruebas sobre el software escrito para la solución exacta que tendrá como objetivo evaluar su precisión. Los geoneutrinos muestran ser de utilidad para el estudio de la composición química de la Tierra, sin embargo la resolución de los detectores es una limitante significativa; se esperan avances en este ámbito durante los próximos añosGeocientíficoPregrado48 hojasapplication/pdfengUniandesGeocienciasFacultad de CienciasDepartamento de Geocienciasinstname:Universidad de los Andesreponame:Repositorio Institucional SénecaGeoneutrino oscillations approach to discriminate distributions of HPE in the earth's mantleTrabajo de grado - Pregradoinfo:eu-repo/semantics/bachelorThesishttp://purl.org/coar/resource_type/c_7a1fhttp://purl.org/coar/version/c_970fb48d4fbd8a85Texthttp://purl.org/redcol/resource_type/TPManto terrestreGeodinámicaEstratigrafíaGeocienciasPublication2e3cac64-ccc2-42c3-b3f9-2ef8e094ba71virtual::14846-12e3cac64-ccc2-42c3-b3f9-2ef8e094ba71virtual::14846-1https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0000008419virtual::14846-1ORIGINALu807125.pdfapplication/pdf5047734https://repositorio.uniandes.edu.co/bitstreams/64fb981e-4138-4a9c-90d4-1fdeee7c2439/download5b7c4c2ea512dde307f99843018e5f43MD51TEXTu807125.pdf.txtu807125.pdf.txtExtracted texttext/plain50526https://repositorio.uniandes.edu.co/bitstreams/0efe95ab-2a19-4636-afd6-3796cbbcfb3f/download55c3bba35b94dab035ef0defc07de7a4MD54THUMBNAILu807125.pdf.jpgu807125.pdf.jpgIM Thumbnailimage/jpeg9050https://repositorio.uniandes.edu.co/bitstreams/42450bb7-2e3c-4153-a1ed-5f6217180e81/download0b51da3fab43eb265ffe691e631d1d74MD551992/39740oai:repositorio.uniandes.edu.co:1992/397402024-03-13 15:18:27.67http://creativecommons.org/licenses/by-nc-sa/4.0/open.accesshttps://repositorio.uniandes.edu.coRepositorio institucional Sénecaadminrepositorio@uniandes.edu.co
