The importance of this process holds in the quantification of the effect on the cross section that an interactive potential produces before particle annihilation. In order to provide insight into the Sommerfeld enhancement we analytically compute it for the potential well and the attractive Coulomb potential. Finally, within the use of a numerical program we compute the Sommerfeld enhancement for the Yukawa potential since it is not analytically solvable5 p.application/pdfengcc-by-nc-nd (c) Jiménez, 2018http://creativecommons.org/licenses/by-nc-nd/3.0/es/Teoria quànticaMatèria fosca (Astronomia)Treballs de fi de grauQuantum theoryDark matter (Astronomy)Bachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
