Some corollary quests for a candidate in some of the many possible model frameworks considering DAMA/NaI data
On the basis of the obtained 6.3 σ model-independent result, corollary
investigations can also be pursued on the nature of the Dark Matter particle candidate.
This latter investigation is instead model-dependent
and -- considering the large uncertainties which exist on the
astrophysical, nuclear and particle physics
assumptions and on the theoretical and experimental
parameters needed in the calculations -- has no general
meaning (as it is also the case of exclusion plots
and of the Dark Matter particle parameters evaluated in indirect
Various candidates, kinds of couplings with ordinary matter and implications, cross sections, nuclear form factors, spin factors, scaling laws, halo models, priors, etc. can be considered. The results briefly summarized in the following are not exhaustive at all of the many scenarios possible at present level of knowledge. For example other halo models and/or related parameters can be considered, etc. For some discussions on theoretical and experimental uncertainties existing in model-dependent analyses (of whatever nature in the field: allowed volumes/regions or exclusion plots or DM particle parameters from indirect searches) see e.g. Riv. N. Cim. 26 n.1 (2003) 1, Int. J. Mod. Phys. D13 (2004) 2127, Int. J. Mod. Phys. A 21 (2006), Eur. Phys. J. C 47 (2006) 263, trasparencies in the Download section and in literature.
For simplicity, the results of corollary quests for a candidate particle are given in terms of allowed regions obtained as superposition of the configurations corresponding to likelihood function values distant more than 4σ from the null hypothesis (absence of modulation) in each of the several (but still a very limited number) of the possible astrophysical, nuclear and particle Physics model frameworks.
