We extend this formula by considering two corrections: one takes into account the finite mass of the hypernucleus in terms of a Λ reduced mass and the other implements the effects of charge symmetry breaking (CSB). Both corrections are found non-negligible for finite hypernuclei. Moreover, our study reveals some inconsistencies in the SΛ data of mirror hypernuclei, preventing us from obtaining a well-determined CSB parameter5 p.application/pdfengcc-by-nc-nd (c) Corts, 2020http://creativecommons.org/licenses/by-nc-nd/3.0/es/HipernucliEnergia de separacióTreballs de fi de grauHypernucleiSeparation energyBachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
