Hypertriton radius calculated from the $\Lambda$ separation energy using the pionless EFT~ (blue band) and a simple quantum mechanical model~ (dashed black line). The measured hypertriton radius is shown as a red band. The red point represents $B_\Lambda$, which is determined from the intersection of the central values of the EFT calculation and the measured radius. The red contour is the total uncertainty of the measurement. The vertical lines represent the obtained value of $B_\Lambda$ (middle full line) and its uncertainty (outer dashed lines). In the lower panel the $B_\Lambda$ world average~ is shown.
