Closing the Window on Strongly Interacting Dark Matter

Autor: Mack, Gregory D., Manohar, Adithya

Constraints are placed on the spin-independent interaction cross section of dark matter with regular matter by refining two methods. First, dark matter--cosmic ray interactions are considered, wherein cosmic ray protons collide with dark matter to co

Conservative Constraints on Dark Matter Annihilation into Gamma Rays

Autor: Mack, Gregory D., Jacques, Thomas D., Beacom, John F., Bell, Nicole F., Yuksel, Hasan

Publikováno v: Phys.Rev.D78:063542,2008

Using gamma-ray data from observations of the Milky Way, Andromeda (M31), and the cosmic background, we calculate conservative upper limits on the dark matter self-annihilation cross section to monoenergetic gamma rays, _{gamma gamma}, ove

Towards Closing the Window on Strongly Interacting Dark Matter: Far-Reaching Constraints from Earth's Heat Flow

Autor: Mack, Gregory D., Beacom, John F., Bertone, Gianfranco

Publikováno v: Phys.Rev.D76:043523,2007

We point out a new and largely model-independent constraint on the dark matter scattering cross section with nucleons, applying when this quantity is larger than for typical weakly interacting dark matter candidates. When the dark matter capture rate

Upper Bound on the Dark Matter Total Annihilation Cross Section

Autor: Beacom, John F., Bell, Nicole F., Mack, Gregory D.

Publikováno v: Phys.Rev.Lett.99:231301,2007

We consider dark matter annihilation into Standard Model particles and show that the least detectable final states, namely neutrinos, define an upper bound on the total cross section. Calculating the cosmic diffuse neutrino signal, and comparing it t
