Análisis experimental del proceso de redispersión Σ-p en la reacción γd→K+Σ-p para energías del fotón entre 1.9 y 2.3 GeV

Abstract

One of the main studies in modern physics is strong interaction, interaction between quarks and gluons that allows them to be found together in the hadrons. The study of the reaction γd→K+Σ-p is the objective of the institutionalized research project and may contribute to the study of these interactions, and in particular to the gathering of information in the dynamics of hadrons containing strange quarks due to the lack of information. In this work, a study of the reaction γd→π+π-pn was made as contribution to the research work, due to the fact that this reaction is one of the main sources of contamination in this research. To study the reaction, methods currently employed in particles physics were used, such as particle selection with Δβ, particle reconstruction through missing mass, and others, until the reaction in interest was filtered. The study is made from the analysis of experimental data facilitated by the CLAS collaboration, recorded with the CLAS (CEBAF Large Acceptance Spectrometer) detector during period g13 in the Hall-B of the Thomas Jefferson National Accelerator Laboratory in Virginia, USA.
