Formation of small-scale structure in SUSY CDM
S. Hofmann, D. J. Schwarz, H. Stocker
The lightest supersymmetric particle, most likely the lightest neutralino, is one of the most prominent particle candidates for cold dark matter (CDM). We show that the primordial…
Damping scales of neutralino cold dark matter
Stefan Hofmann, Dominik J. Schwarz, Horst Stoecker
The lightest supersymmetric particle, most likely the neutralino, might account for a large fraction of dark matter in the Universe. We show that the primordial spectrum of density…
Strange quark stars within the Nambu-Jona-Lasinio model
M. Hanauske, L. M. Satarov, I. N. Mishustin +2
We investigate the properties of charge-neutral -equilibrium cold quark matter within the Nambu-Jona-Lasinio model. The calculations are carried out for different ratios of coup…
Phase Transition to Hyperon Matter in Neutron Stars
Jurgen Schaffner-Bielich, Matthias Hanauske, Horst Stocker +1
Recent progress in the understanding of the high density phase of neutron stars advances the view that a substantial fraction of the matter consists of hyperons. The possible impac…
Neutron star properties in a chiral SU(3) model
M. Hanauske, D. Zschiesche, S. Pal +3
We investigate various properties of neutron star matter within an effective chiral model. The predictions of this model are compared with a Walecka-type m…
Neutron star properties in the quark-meson coupling model
S. Pal, M. Hanauske, I. Zakout +2
The effects of internal quark structure of baryons on the composition and structure of neutron star matter with hyperons are investigated in the quark-meson coupling (QMC) model. T…
