Latest results from Jefferson Lab HKS experiment

The goal of Jefferson Lab HKS experiment is to obtain high resolution spectroscopy for $^{12}_\Lambda$B, $^{28}_\Lambda$Al and $^{7}_\Lambda$He hypernuclei. Recently, to further improve the precision of the binding energy determination, we have done a thorough new analysis with better tracking resolution at spectrometer focal planes and a new kinematics calibration procedure. In this talk, I will present the latest spectra of $^{12}_\Lambda$B, $^{28}_\Lambda$Al and $^{7}_\Lambda$He and compare them to the most recent theoretical predictions.
