  1. Ambrosio, ; M, ; others, , Limits on dark matter WIMPs using upward-going muons in the MACRO detector, Physical Review D, vol. 6008 no. 8 (October, 1999), pp. art. no.-082002 .

    We perform an indirect search for weakly interacting massive particles (WIMPs) using the MACRO detector to look for neutrino-induced upward-going muons resulting from the annihilation of WIMPs trapped in the Sun and Earth. The search is conducted in various angular cones centered on the Sun and Earth to accommodate a range of WIMP masses. No significant excess over the background from atmospheric neutrinos is seen. We set experimental flux limits on the upward-going muon fluxes from the Sun and the Earth. These limits are used to constrain neutralino particle parameters from supersymmetric theory, including those suggested by recent results from DAMA-NaI. ©1999 The American Physical Society.
