Popis: | In this work we propose a new method to measure the evolution of the neutron skin thickness between different isotopes. We consider antiproton-nucleus interactions close to the production threshold of ${\Lambda}\overline{\Lambda}$ and ${\Sigma}\overline{\Lambda}$ pairs. At low energies, ${\Lambda}\overline{\Lambda}$ pairs are produced in p + p collisions, while ${\Sigma}\overline{\Lambda}$ pairs can only be produced in p + n interactions. Measuring these cross sections provides information on the neutron skin thickness Comment: 4 pages, 3 figures, 14th International Conference on Hypernuclear and Strange Particle Physics - HYP2022 |
