Fresh view of the hot brown dwarf HD 984 B through high-resolution spectroscopy
J. C. Costes, J. W. Xuan, A. Vigan +26
Context. High-resolution spectroscopy has the potential to drive a better understanding of the atmospheric composition, physics, and dynamics of young exoplanets and brown dwarfs,…
The semi-classical approach to the exclusive electron scattering
W. M. Alberico, G. Chanfray, J. Delorme +2
The semiclassical approach, successfully applied in the past to the inelastic, inclusive electron scattering off nuclei, is extended to the treatment of exclusive processes. The fi…
Neutrino-Oxygen interactions: role of nuclear physics in the atmospheric neutrino anomaly
J. Marteau, J. Delorme, M. Ericson
The apparent anomaly in the ratio of muon to electron atmospheric neutrinos first observed by Kamiokande and IMB has been confirmed by Super-Kamiokande and Soudan-2. The experiment…
Axial and Vector Correlator Mixing in Hot and Dense Hadronic Matter
G. Chanfray, J. Delorme, M. Ericson +1
We study the manifestations of chiral symmetry restoration which have a significance for the parity mixing. Restricting to pions and nucleons we establish a formalism for the expre…
Correlator mixing and mass reduction as signals of chiral symmetry restoration
J. Delorme, M. Ericson, P. A. M. Guichon +1
Chiral symmetry restoration in a dense medium is to some extent a consequence of the nuclear pion cloud. These pions induce a mixing of the axial and vector current contributions i…
Pion Scalar Density and Chiral Symmetry Restoration at Finite Temperature and Density
G. Chanfray, D. Davesne, J. Delorme +2
This paper is devoted to the evaluation of the pionic scalar density at finite temperature and baryonic density. We express the latter effect in terms of the nuclear response evalu…
