abstract

Strong interaction level shifts and widths in $\Sigma^-$ atoms are analyzed by using a $\Sigma$ nucleus optical potential constructed within the relativistic mean field approach. The analysis leads to potentials with a repulsive real part in the nuclear interior. The data are sufficient to establish the size of the isovector meson--hyperon coupling. Implications to $\Sigma$ hypernuclei are discussed.

    hep-ph 2024-11 reject novelty 4.0 of 10

    Using a 3-flavor NJL model with axions, the authors find that a CP-violating angle theta=pi reduces the chiral transition density and, with a vector repulsion, yields stable hybrid neutron stars with enhanced f-mode o...
