Anharmonic O(N) oscillator model in next-to-leading order of the 1/N expansion
Alan Dzhioev, J. Wambach, A. Vdovin +1
An extended Holstein-Primakoff mapping which incorporates both single- and double boson mappings is used in the context of O(N+1) anharmonic oscillator with the global symmetry bro…

Dropping Sigma-Meson Mass and In-Medium Pion-Pion Correlations
P. SchucK, Z. Aouissat, G. Chanfray +1
The influence of a dropping sigma-meson mass on previously calculated in-medium pion-pion correlations in the J=I=0 (sigma-meson) channel is investigated. It is found that the inva…

In-Medium Correlations in the '-Meson'-Channel
P. Schuck, Z. Aouissat, F. Bonutti +4
The present status of the in-medium invariant mass distribution in the sigma-meson channel around the threshold is reviewed from the theory side and contrasted with recent ex…
