Indirect, direct and collider detection of neutralino dark matter in the minimal supergravity model

Indirect, direct and collider detection of neutralino dark matter in the minimal supergravity model
Indirect, direct and collider detection of neutralino dark matter in the minimal supergravity model
We examine the prospects for supersymmetry discovery in the minimal supergravity (mSUGRA) model via indirect detection of neutralino dark matter. We investigate rates for muon detection in neutrino telescopes, and detection of photons, positrons and anti-protons by balloon and space based experiments. We compare the discovery reach in these channels with the reach for direct detection of dark matter, and also with the reach of collider experiments such as Fermilab Tevatron, CERN LHC and a ?s = 0.5–1 TeV linear e+e? collider. We pay particular attention to regions of model parameter space in accord with recent WMAP results on the dark matter density of the universe. We find that third generation direct dark matter detection experiments should be able to cover the entire WMAP allowed portion of the hyperbolic branch/focus point (HB/FP) region of parameter space, while the IceCube neutrino telescope can cover almost all this region. This is in contrast to the case of the CERN LHC or a linear e+e? collider, where only a fraction of the HB/FP region can be accessed. In addition, we show that detection of ?s, e+s and ¯ps should occur in much of the HB/FP region, as well as in the low m1/2 portion of the A annihilation funnel, and will be complementary to searches via colliders in these regions.

Abstract

We examine the prospects for supersymmetry discovery in the minimal supergravity (mSUGRA) model via indirect detection of neutralino dark matter. We investigate rates for muon detection in neutrino telescopes, and detection of photons, positrons and anti-protons by balloon and space based experiments. We compare the discovery reach in these channels with the reach for direct detection of dark matter, and also with the reach of collider experiments such as Fermilab Tevatron, CERN LHC and a ?s = 0.5–1 TeV linear e+e? collider. We pay particular attention to regions of model parameter space in accord with recent WMAP results on the dark matter density of the universe. We find that third generation direct dark matter detection experiments should be able to cover the entire WMAP allowed portion of the hyperbolic branch/focus point (HB/FP) region of parameter space, while the IceCube neutrino telescope can cover almost all this region. This is in contrast to the case of the CERN LHC or a linear e+e? collider, where only a fraction of the HB/FP region can be accessed. In addition, we show that detection of ?s, e+s and ¯ps should occur in much of the HB/FP region, as well as in the low m1/2 portion of the A annihilation funnel, and will be complementary to searches via colliders in these regions.

Published date: 9 August 2004
Additional Information: This was the first paper where discovery reach of indirect detection of neutralino dark matter was compared with the reach for direct detection dark matter experiments and also with the reach of collider experiments such as Fermilab Tevatron, CERN LHC and a sqrt (s)= 0.5-1 TeV linear e+e- collider, demonstrating a high degree of complementarity of the above experiments.
