Some Practical Applications of Dark Matter Research

Two practical spin-offs from the development of cryogenic dark matter detectors are presented. One in materials research, the other in biology.

Some Applications of Semidefinite Optimization from an Operations Research Viewpoint

Singlet scalar dark matter in noncommutative space

In this paper, we examine the singlet scalar dark matter annihilation to becoming the Standard Model particles in the non-commutative space. In the recent decades, many candidates of dark matter have been offered,  but our information about  the nature of dark matter is still limited. There are such particle candidates as  scalar matetr, fermion, boson, gauge boson, etc.; however, they have nei...

BOLOMETRIC DETECTION OF COLD DARK MATTER CANDIDATES: Some Material Considerations*

We discuss the use of crystal bolometers to search for weakly interacting cold dark matter particles in the galactic halo. For particles with spin dependent nuclear interactions, such as photinos, Majorana neutrinos and higgsinos, we show that compounds of boron, lithium, or fluorine are optimal detector components. We give careful estimates of expected cross-sections and event rates and discus...

Some Issues Related to the Direct Detection of Dark Matter

We briefly review some theoretical issues involved in the direct detection of supersymmetric (SUSY) dark matter. After a brief discussion of the allowed SYSY parameter space, we focus on the determination of the traditional neutralino detection rates, in experiments which measure the energy of the recoiling nucleus, such as the coherent and spin induced rates and the dependence of the rate on t...
