2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/105893Using the approximate flavor SU(3) symmetry of strong interactions, we argue for the existence of a new Lambda baryon with J^P=3/2^-, the mass around 1850 MeV, the total width of about 130 MeV, significant branching into the Sigma πand Sigma^{\ast} πstates and a vanishingly small coupling to the N {\bar K} state. This confirms quark model predictions suggesting a new Lambda baryon in the mass range between 1775 MeV and 1880 MeV with a very small coupling to the N {\bar K} state.4 pages, RevTeXHigh Energy Physics - Phenomenologytext
