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…
Single Boson Images Via an Extended Holstein Primakoff Mapping
Zoheir Aouissat
The Holstein-Primakoff mapping for pairs of bosons is extended in order to accommodate single boson mapping. The proposed extension allows a variety of applications and especially…
Dropping Sigma-Meson Mass and In-Medium S-Wave pion-pion Correlations
Z. Aouissat, G. Chanfray, P. Schuck +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…
Symmetry conserving non-perturbative s-wave renormalization of the pion in hot and baryon dense medium
Z. Aouissat, M. Belkacem
A non-perturbative s-wave renormalization of the pion in a hot and baryon rich medium is presented. This approach proceeds via a mapping of the canonical pion into the axial Noethe…
Moments of event observable distributions and many-body correlations
M. Belkacem, Z. Aouissat, M. Bleicher +2
We investigate event-by-event fluctuations for ensembles with non-fixed multiplicity. Moments of event observable distributions, like total energy distribution, total transverse mo…
