Dark Matter: Key Issues

Statistical issues in dark matter detection

Statistical techniques used to analyse data from direct detection dark matter experiments are reviewed with an emphasis on general issues which could benefit from further study. In order to illustrate these issues three case studies are presented of detectors operating in different statistical regimes which require novel approaches to data analysis. (From the workshop ‘Advanced Statistical Tech...

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...

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...

Dark matter and dark radiation

Lotty Ackerman, Matthew R. Buckley, Sean M. Carroll, and Marc Kamionkowski California Institute of Technology, Pasadena, California 91125, USA (Received 16 December 2008; published 23 January 2009) We explore the feasibility and astrophysical consequences of a new long-range Uð1Þ gauge field (‘‘dark electromagnetism’’) that couples only to dark matter, not to the standard model. The dark matter...
