The new FERMI data on the diffuse Galactic gamma rays shows a large unidentifiedcomponent. The compatibility with a dark matter annihilation (DMA) contribution has been investigated. Furthermore, the data is compared with extremely precise new data on the outer rotation curve from maser interferometry and gasflaring. Both measurements indicate a ring of dark matter in the outer Galaxy in...

The thermally produced LSP has long believed to be the best candidate
for dark matter in the Universe. However, recently reported PAMELA/Fermi's
observations on high energy cosmic positrons' excess seem to require
a new dark matter theory. It will be pointed out that they do not necessarily imply the presence of a new dark matter theory, and discussed how PAMELA/Fermi data can be...

I look at the MSSM augmented by righthanded neutrinos and 3 new singlets. In addition a new U(1) gauge symmetry, with a Fayet-Iliopoulos term, under which two of the singlets are (oppositely) charged is added. Rather than breaking supersymmetry, the F-I term will be balanced by a MSSM flat direction vacuum expectation value during inflation. Thus ”all MSSM fields vanishes” is not a minimum,...

We calculate the cosmic ray positron and antiproton spectra of a gauge-Higgs dark matter candidate in a recently proposed warped five-dimensional SO(5) xU(1) gauge-Higgs unification model. The stability of the gauge-Higgs boson is guaranteed by the H parity under which only the Higgs boson is odd at low energy. The 4-point vertices of HHWW and HHZZ, allowed by H parity conservation, have...

The E6SSM is an E6 GUT group inspired supersymmetric model. The low energy theory contains an extra U(1) gauge group and a standard model singlet that is only charged under this extra U(1). The LSP dark matter candidate typically comes from a new and approximately decoupled sector containing two inert extra generations of Higgsinos and singlinos, where inert means that their scalar...

If broken susy is discovered at Fermilab or the LHC it may become more pressing to study the possibility of an exact susy phase to which an enhanced transition probability could arise in dense matter. In collaboration with Peter Biermann several astrophysical anomalies are addressed which could be attributed to this phase. Among these are the gap in the black hole mass distribution, the...
