1 On Symmetric/Asymmetric Light Dark Matter Hai-Bo Yu University of Michigan, Ann Arbor Exploring Low-Mass Dark Matter Candidates PITT PACC, 11/16/2011

2 Motivations Traditionally, we focus on O(100 GeV) dark matter. Hints for light dark matter DAMA, CoGeNT, CRESST (10 GeV); Dan Hooper`s talk; 511 kev gamma rays (MeV) Challenges for light DM models (1MeV-10GeV) CMB constraints; Collider constraints In this talk, we will examine cosmological, astrophysical and collider constraints on light DM. Ways to evade these bounds.

3 Outline Theoretical models: usual thermal WIMP and asymmetric DM The CMB and collider constraints; light DM prefers light mediators DM halo shape constrains on mediator mass Implications for direct detection

4 Theory: Thermal WIMP SM SM (DM has zero chemical potential) - Early Universe DM density: Annihilation cross section - Late Universe

5 Theory: Asymmetric DM Nussinov (1985); Kaplan (1992); Hooper, March- Russell, West (2004); Kaplan, Luty, Zurek (2009)... Mass (Ω DM /Ω b )m p 5 GeV - DM density: Primordial DM asymmetry Annihilation cross section - Early Universe Late Universe Anti-DM is negligible now! Look for accumulation McDermott, HBY, Zurek (2011); Zentner, Hearin (2011)

6 CMB Constraints Energy deposition from DM annihilation at z 1000 Ionize atoms Distort CMB power spectra de dtdv = ρ2 cω 2 CDM(1 + z) 6 f σv CMB m f 1(e ± ); f 0.2(q ± ) f 0(ν) WMAP7 95% C.L. For symmetric DM f σv CMB < cm 3 /s m GeV Galli, Iocco, Bertone, Melchiorri (2011)

7 Evade CMB constraints Symmetric DM Annihilate to neutrinos Annihilation cross section is p-wave suppressed σv CMB (v CMB /v f ) 2 σv f, v CMB 10 8, v f 0.3 Asymmetric DM - -

8 Asymmetric Case The present anti-dm to DM ratio Lin, Zurek, HBY (2011) r = n n ( ) exp [ η σv 0.264m pl m g /x f ] CMB constraints for ADM primordial DM asymmetry η Ω CDM m 2r (1 + r) 2 f σv < cm 3 /s m GeV ρ c s 0 if r 1 The anti-dm to DM ratio is exponentially suppressed by the annihilation cross section, so does the energy injection rate. In the ADM scenario, the CMB bounds set a minimal annihilation cross section.

9 CMB Bounds in ADM minimal annihilation cross section ADM can avoid CMB constraints rather naturally. Large annihilation cross section How to get large <σv>? Lin, Zurek, HBY (2011)

10 Achieving Large <σv> _ ϕ SM SM _ ϕ ϕ m <m φ m >m φ Collider constraints m φ p O(100 GeV) m φ p O(100 GeV) Mono-jet+missing energy No collider constraints ϕ mass? Couple to the SM? Astrophysical/Cosmological constraints

11 A Simple Argument q - jet q - m φ p T O(100 GeV) _ ϕ σv g2 g2 SM m2 m 4 φ SM SM m φ p O(100 GeV) σ C g2 g2 SM p2 m 4 φ σv p2 m 2 σ C g2 g2 SM p 2 σv m 4 φ p 2 m 2 Strong constraints Weak

12 An Effective Theory missing energy+mono-jet q - jet q m φ p O(100 GeV) - Goodman, Ibe, Rajarama, Shepherd, Tait, HBY (2010)

13 Tevatron Constraints LHC (expected) D5,D7 (GeV) M * Tevatron WIMP cross section D5 D6 D7 D8 D6,D8 10 m! 2 10 (GeV) Goodman, Ibe, Rajarama, Shepherd, Tait, HBY (2010) m φ p O(100 GeV) 3 10

14 Lighter Mediator Case Graesser, Shoemaker, Vecchi (2011) m φ p O(100 GeV) g SM = g B 3 < BR(φ ) =1 If not g SM g SM / BR Lin, HBY, Zurek (2011) m >m φ? m <m φ p O(100 GeV) OK

15 How light can ϕ be? If ϕ is nearly massless, DM mass has to be O(1 TeV). ϕ The mediator can lead to DM selfinteractions. Constraints on DM self-interactions: the Bullet Cluster DM halo shapes Feng, Kaplinghat, Tu, HBY (2009)

16 The Bullet Cluster σ cm2 <1 m g Markevitch, Gonzalez, Clowe, Vikhlinin, David, Forman, Jones, Murray, Tucker (2003) = cm2 GeV

17 Ellipticity of DM Halos If DM self-interactions are strong enough to create O(1) velocity change, they can erase the anisotropy of the DM velocity dispersion and create spherical halos. There are elliptical galaxies and clusters. We consider the well-studied, nearby (about 25 Mpc away) elliptical galaxy NGC720. v 2 r (240 km/s) 2, ρ 4 GeV/cm 3 Feng, Kaplinghat, Tu, HBY (2009); Feng, Kaplinghat, HBY (2009);

18 Ellipticity of DM Halos We consider the rate to create O(1) velocity change Γ k = d 3 v 1 d 3 v 2 f(v 1 )f(v 2 )(n v rel σ )(vrel/v 2 0) 2 Determine the coefficient by comparing with simulation. > years Γ 1 k σ m 3 cm2 < g = cm2 GeV About two orders of magnitude stronger than the bound from the Bullet Cluster. Feng, Kaplinghat, HBY (2009); Lin, HBY, Zurek (2011)

19 Lower Mass Bounds on ϕ Lin, HBY, Zurek (2011) For DM mass 1 MeV-10 GeV, ϕ mass > 40 KeV-40 MeV

20 Cosmology of Massive ϕ ϕ SM g SM? SM Dark sector thermalizes with the SM sector Γ φ >H(T m ) g SM > Inverse decay keeps ϕ in thermal equilibrium. Decay before BBN; Two sectors evolve differently Γ φ > s g SM > 10 11

21 Direct Detection Assume a vector ϕ ϕ N Lin, HBY, Zurek (2011) N Consistent with all constraints Two sectors are thermalized Wide range! Neutrino background? Strigari (2009)

22 Electron Scattering ϕ e Lin, HBY, Zurek (2011) e Bjorken, Essig, Schuster, Toro (2009) Ge line: Essig, Mardon, Volansky (2011)

23 Summary Many constraints become relevant if DM is light. ADM can avoid CMB bounds quite naturally. Light DM prefers to have light mediators to avoid collider constraints.
