Descripción del proyecto
Una avanzada técnica de análisis de datos podría aportar nueva información sobre la verdadera naturaleza de la materia oscura
El modelo estándar de la física de partículas ha predicho satisfactoriamente muchos resultados experimentales. Sin embargo, sigue sin permitir explicar algunos fenómenos fascinantes, como el gran exceso de materia oscura no observable del universo. En el proyecto DARKJETS, financiado por el Consejo Europeo de Investigación, se examinará si la materia oscura puede consistir en partículas creadas durante las colisiones protón-protón en el Gran Colisionador de Hadrones (LHC, por sus siglas en inglés) de la Organización Europea de Investigación Nuclear. Los investigadores, en su búsqueda de señales que indiquen la presencia de partículas de materia oscura, utilizarán un nueva técnica de análisis de datos en tiempo real, así como una nueva firma de búsqueda, a fin de superar las limitaciones de almacenamiento de datos. Dado que el LHC pronto reanudará sus operaciones, el proyecto DARKJETS representa una oportunidad única para mejorar de forma notable la comprensión de la materia oscura.
Objetivo
The Standard Model of Particle Physics describes the fundamental components of ordinary matter and their interactions. Despite its success in predicting many experimental results, the Standard Model fails to account for a number of interesting phenomena. One phenomenon of particular interest is the large excess of unobservable (Dark) matter in the Universe. This excess cannot be explained by Standard Model particles. A compelling hypothesis is that Dark Matter is comprised of particles that can be produced in the proton-proton collisions from the Large Hadron Collider (LHC) at CERN.
Within this project, I will build a team of researchers at Lund University dedicated to searches for signals of the presence of Dark Matter particles. The discovery strategies employed seek the decays of particles that either mediate the interactions between Dark and Standard Model particles or are produced in association with Dark Matter. These new particles manifest in detectors as two, three, or four collimated jets of particles (hadronic jets).
The LHC will resume delivery of proton-proton collisions to the ATLAS detector in 2015. Searches for new, rare, low mass particles such as Dark Matter mediators have so far been hindered by constraints on the rates of data that can be stored. These constraints will be overcome through the implementation of a novel real-time data analysis technique and a new search signature, both introduced to ATLAS by this project. The coincidence of this project with the upcoming LHC runs and the software and hardware improvements within the ATLAS detector is a unique opportunity to increase the sensitivity to hadronically decaying new particles by a large margin with respect to any previous searches. The results of these searches will be interpreted within a comprehensive and coherent set of theoretical benchmarks, highlighting the strengths of collider experiments in the global quest for Dark Matter.
