Tecnicas Experimentales de Identificación y Reconstrucción de Partículas en Física de Energías Medias

Abstract

The work will be focused in two scenarios: Direct and indirect identification of particles. The former is helpful when the particle mean decay path is comparable with the detector size such that, on average, they do not decay before reaching the corresponding detector; in this case, there exist some methods to perform the data analysis such as mass cuts, time of flight and energy loss. The latter is related to either particles decaying on its way through the detectors or slow particles that cannot surpass the detection threshold; in this case, it is necessary to reconstruct the particles using methods based on the conservation laws of energy and momentum such as invariant mass and missing mass. The analysis will be performed using the software ROOT and the implementation of described methods to two nuclear reactions.
