Explore experiments of few-nucleon scattering to investigate three-nucleon forces in this 34-minute conference talk by Kimiko Sekiguchi from Tokyo Tech. Recorded as part of the Opportunities and Challenges in Few-Body Physics: Unitarity and Beyond conference at the Kavli Institute for Theoretical Physics, delve into the current status of few-body physics near unitarity. Examine the connections between atomic and nuclear physics through phenomena like the three-body Efimov effect. Gain insights into the cross-fertilization between theory and experiment across various research areas, including nuclear, atomic, molecular, condensed matter, high-energy, and mathematical physics, with a focus on universality and its organizing principles.
