Meson-Nucleon Interactions: Meson-Nucleon Interactions
- Justin Stevens (William & Mary)
Large scale fits to pionic atoms data show that the in-medium pion-nucleon
isovector scattering length b1 gets renormalized in pionic atoms by 30-40%
away from its free-space value [1], apparently owing to the decrease of the
pion decay constant in the nuclear medium in terms of the pion-nucleon sigma
term [2]. Accepting the validity of this approach, we extracted this sigma
term from a...
The behavior of the $\phi$ meson in nuclear matter has attracted renewed interest because
of (recent and future) experiments that aim to study its properties in nuclei [1-3]. Theoretically,
many works have however been conducted assuming infinite nuclear matter [4-5], which is
not realistic from an experimental point of view. To relate theoretical predictions with experimental
observables,...
