Abstract
Annual modulation due to the Earth's motion around the Sun is a well-known signature of the expected weakly interacting massive particle (WIMP) signal induced in a solid state underground detector. In the present paper, we di scuss the prospects of this technique on statistical grounds, introducing a nnual-modulation sensitivity plots for the WIMP-nucleon scalar cross-sectio n for different materials and experimental conditions. The highest sensitiv ity to modulation is found in the WIMP mass interval 10 less than or simila r to m(W) less than or similar to 130 GeV, the actual upper limit depends o n the choice of the astrophysical parameters, while the lowest values of th e explorable WIMP-nucleon elastic cross-sections fall in most cases within one order of magnitude of the sensitivities of the present direct detection WIMP searches.
