Description
In this talk, I'll show our first implementation of the finite-volume $N/D$ representation to study two-baryon interactions from lattice QCD data. We include the left-hand cut induced by one-pion exchange in this formalism, and study the H-dibaryon at the SU(3)$_\text{F}$-symmetric point, with a pion mass around $417$MeV. The $N/D$ formalism is also compared to the Luscher quantization condition, used to describe the same system via effective-range expansions. Our results show a mild but statistically significant effect produced by the inclusion of the left-hand cut, especially on the binding energy of the shallow bound H-dibaryon here.
