2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/182573In this article we consider the three-particle decays $χ_{b0,2}\to J/ψc\bar c\to J/ψD\bar D+X$. We present the analytical formulae for the differential widths of these decays, the numerical values of their integrated widths and check the duality relation that connects the decays $χ_{b0,2}\toψc\bar c$ with the two-particle decays $χ_{b0,2}\to J/ψ(c\bar c)$. We also study the possibility of observing the $χ_{b0,2}\to J/ψDD+X$ mode at Tevatron and LHC colliders.8 pages, 3 figures; minor changesHigh Energy Physics - Phenomenologytext
