标题： Sensitivity plots for WIMP direct detection using the annual modulation signature

摘要： 由于地球绕太阳运动而引起的年调制是预期的由WIMP（弱相互作用大质量粒子）在地下的固态探测器中诱导信号的一个众所周知的特征。在本文中，我们从统计学的角度讨论了这种技术的前景，并为不同的材料和实验条件引入了WIMP-核子标量截面的年调制灵敏度图。最高的调制灵敏度出现在WIMP质量区间10 GeV < m_W < 130 GeV内，实际的上限取决于天文学参数的选择，而可探索的WIMP-核子弹性截面的最低值通常落在当前直接探测WIMP搜索灵敏度的一个数量级以内。 显示英文摘要

摘要： Annual modulation due to the Earth's motion around the Sun is a well known signature of the expected WIMP signal induced in a solid state underground detector. In the present letter we discuss the prospects of this technique on statistical grounds, introducing annual-modulation sensitivity plots for the WIMP-nucleon scalar cross section for different materials and experimental conditions. The highest sensitivity to modulation is found in the WIMP mass interval 10 GeV< m_W < 130 GeV, the actual upper limit depending from the choice of the astrophysical parameters, while the lowest values of the explorable WIMP-nucleon elastic cross-sections fall in most cases within one order of magnitude of the sensitivities of present direct detection WIMP searches.
