Dark matter scenarios in the minimal SUSY B-L model
We perform a study of the dark matter candidates of a constrained version of
the minimal R-parity-conserving supersymmetric model with a gauged
. It turns out that there are four additional candidates for dark
matter in comparison to the MSSM: two kinds of neutralino, which either
correspond to the gaugino of the or to a fermionic bilepton, as
well as "right-handed" CP-even and -odd sneutrinos. The correct dark matter
relic density of the neutralinos can be obtained due to different mechanisms
including new co-annihilation regions and resonances. The large additional
Yukawa couplings required to break the radiatively often lead to
large annihilation cross sections for the sneutrinos. The correct treatment of
gauge kinetic mixing is crucial to the success of some scenarios. All
candidates are consistent with the exclusion limits of Xenon100.Comment: 45 pages, 22 figures; v2: extended discussion of direct detection

Is economics scientific discipline loyal to its own starting points and fundamental principles?
The article argues that the economic scientific community, by disregarding the importance of freedom which was essential for its emancipation and market as its key criterion of choice, is disloyal to its own starting points and fundamental principles. By dictating strict methodological rules the neoclassical school has consolidated its
monopoly position within economics. The article highlights that this methodological normativism is substantially reducing the diversity of methodological approaches and that such restriction of freedom has become a source of subordination within economic community. The author argues that today a new emancipation is needed, with a strong emphasis on the freedom to forge new approaches and acute awareness of the fact that no theoretical platform can persist without adequate demand for its findings in the science market
