NUCLEAR SPIN STRUCTURE IN DARK-MATTER SEARCH: THE ZERO MOMENTUM TRANSFER LIMIT Bednyakov V. A., imkovic F. The calculation of spin-dependent matrix elements relevant to scattering of weakly interacting massive particles (WIMP) on nuclei is reviewed. A comprehensive list, to our knowledge, of the proton and neutron total spin expectation values (< S p > and < S n > ) calculated within different nuclear models is presented. These values allow a conclusion about the event rate expected in direct dark matter search experiments due to spin-dependent neutralino-nucleon interaction, provided neutralino is a dark matter particle. |
