AA.00001: Solving the riddle and mystery of the enigmatic neutrino Invited Speaker: J.F. Wilkerson Over the past generation, a series of intricate and challenging experiments have revealed that neutrinos have surprising, unexpected properties. These revolutionary discoveries unveiled shortcomings in the standard model of fundamental interactions and our understanding of the role neutrinos play in the universe. Many intriguing questions remain unanswered with profound implications. Might neutrinos offer an explanation of the matter-antimatter asymmetry? What are the masses of the neutrinos and the origin of these masses? Can the hints of sterile neutrinos be substantiated? This talk will review our current understanding of neutrinos, discuss the neutrino’s intertwined relationship with nuclear physics, astrophysics, and cosmology, and examine the prospects for further discoveries as today’s generation of precision measurements move forward. |

AA.00002: Topics on (e,e'K$^+$) spectroscopy of $\Lambda$ hypernuclei at JLab Invited Speaker: Satoshi N Nakamura Spectroscopic study of electro-produced $\Lambda$ hypernuclei started at Jefferson Lab in 2000. Though it was known that spectroscopy of electro-produced hypernuclei has many advantages over other meson-produced hypernuclear spectroscopy, there are many experimental difficulties such as small production cross-section, huge elecron background and so on. After more than 15 years efforts by an international collaboration lead by Japan and US groups, the spectroscopy of $\Lambda$ hypernuclei has finally established by introducing novel experimental techniques. JLab hypernuclear collaboration is now preparing new experiments such as E12-15-008 (study of isospin dependence of $\Lambda$ hypernuclei) and E12-17-003 (study of $\Lambda$N interaction by study of $\Lambda$nn resonance). I will overview unique features of spectroscopy of $\Lambda$ hypernuclei with electron beams and discuss future prospects. Current status of $\Lambda$nn resonance or bound state search experiment which will start very soon at JLab will be also reported. |
