Direct detection of dark matter in SU(5) x U(1) supergravity

We compute the scattering rates for the lightest neutralino \chi^0_1 in the forthcoming germanium (^{73}{\rm Ge}+^{76}{\rm Ge}) detector and a proposed lead detector (^{207}{\rm Pb}), within the framework of SU(5)\times U(1) supergravity. We find that in only a small portion (\lsim10\%) of the param...

description We compute the scattering rates for the lightest neutralino \chi^0_1 in the forthcoming germanium (^{73}{\rm Ge}+^{76}{\rm Ge}) detector and a proposed lead detector (^{207}{\rm Pb}), within the framework of SU(5)\times U(1) supergravity. We find that in only a small portion (\lsim10\%) of the parameter spaces of this class of models, are the rates in the germanium detector above the expected initial experimental sensitivity of 0.1 events/kg/day. However, a much larger portion (\lsim40\%) of the parameter spaces could be probed with an improved background rejection capability (0.01 events/kg/day) and/or a more sensitive detector (^{207}{\rm Pb}).

We find that in only a small portion ($\lsim10\%$) of the parameter spaces of this class of models, are the rates in the germanium detector above the expected initial experimental sensitivity of 0.1 events/kg/day. However, a much larger portion ($\lsim40\%$) of the parameter spaces could be probed with an improved background rejection capability (0.01 events/kg/day) and/or a more sensitive detector $(~{207}{\rm Pb})$.We compute the scattering rates for the lightest neutralino χ 1 0 in the forthcoming germanium ( 73 Ge + 76 Ge ) detector and a proposed lead detector ( 207 Pb), within the framework of SU(5) × U(1) supergravity. We find that in only a small portion (≲ 10%) of the parameter spaces of this class of models, are the rates in the germanium detector above the expected initial experimental sensitivity of 0.1 events/kg/d. However, a much larger portion (≲ 40%) of the parameter spaces could be probed with an improved background rejection capability (0.01 events/kg/d) and/or a more sensitive detector ( 207 Pb).hep-ph/9412237CERN-TH-7520-94CTP-TAMU-63-94ACT-21-94ACT-1994-21CERN-TH-7520-94CTP-TAMU-94-63oai:cds.cern.ch:2733531994-12-05
