摘要
An analytic expression allowing to evaluate the spin-independent detection rate of weakly interacting massive particles as a function of the detector energy threshold for any dark matter mass and absorber material, is presented. The detection rate is calculated taking into account the dynamics of the dark matter particles and the loss of coherence in the neutral-current interactions due to the nuclear form factor. The amplitude of the seasonal modulation in the rate is discussed, showing that, in the case of detectors made of heavy nuclei, the sign of the modulation in the counting rate can be different from the amplitude of the modulation in the dark matter flux.
