(H\) dibaryon away from the \(SU(3)_f\) symmetric point

We present the current status of our efforts in search of \(H\) dibaryon on \(N_f\)=2+1 CLS ensembles away from the \(SU(3)\) flavor symmetric point. Utilizing the distillation framework (also known as LapH) in its exact and stochastic forms, we calculate two-point correlation matrices using large b...

Zusammenfassung:We present the current status of our efforts in search of \(H\) dibaryon on \(N_f\)=2+1 CLS ensembles away from the \(SU(3)\) flavor symmetric point. Utilizing the distillation framework (also known as LapH) in its exact and stochastic forms, we calculate two-point correlation matrices using large bases of bi-local two-baryon interpolators to reliably determine the low-energy spectra. We report the low lying spectrum on several moving frames for multiple ensembles with different lattice spacing and physical volumes. The status of finite-volume analysis to extract the scattering amplitudes is also discussed.
