Symmetric vs Asymmetric TIMPs Can pNGB TIMPs have a symmetric relic density? Φ complex composite scalar with Yield and relic density in the presence of asymmetry: uncharged components ~ λ s motivated by achieving Minimality & Walking (Griest & Seckel 85) (Dynamical realization of scalar singlet DM models) α=0 Specific model example: 'Ultra Minimal TC' (Ryttov & Sannino 09) (Belyaev, M.T.F, Sarkar & Sannino 10)
Symmetric vs Asymmetric TIMPs TIMPs with charged constituents Symmetric relic density of T 0 (Belyaev, M.T.F, Sarkar & Sannino 10) Higgs interactions of T 0 identical to those of φ α=0 T may also have charge radius interaction : In addition T 0 has contact interactions with SM gauge bosons, due to EW charges of U, D: (Preskill 81; Chadha and Peskin 81)
Back to light ADM Most nuclear recoil experiments optimized to heavy WIMPs with little sensitivity to low mass particles O(keV) recoil energies Recently several experiments have reported events close to threshold Region of interest for Solar neutrinos (Schwetz @IDM 10) ~ 5 GeV Dark Matter candidates with ~10 -39 cm 2 spin-independent cross-section remains viable. Spin-dependent cross-sections up to 10 -36 cm 2
Signatures of light ADM Similar to TIMPs light ADM may be a composite scalar or fermion Higgs exchange can naturally provide cross-section up to ~10 -41 Charge radius can provide ~10 -39 cm 2 cm 2 SI cross-sections Large SI and SD cross-sections of fermionic ADM can be realized via magnetic moment interactions (Sigurdson et al 2006, Gardner 08, Heo 09, Masso et al 09, An et al 10, Banks et al 10, Barger et al 10...) (Fit Courtesy of McCabe, M H =150 McCabe 10) Interesting LHC signatures like for TIMPs incl 'monojets' (Goodman et al 10, Bai, Fox & Harnik 10)
Astrophysical aspects of light ADM Long range self-interactions are more tightly constrained by the 'Bullet cluster' (Feng, Kaplinghat and Yu 10)
