之所以称其为“弱作用”，是为了指出粒子受到四大基本力中的另一种——由放射性衰变所产生的弱核力（四大基本力是：引力、电磁力、强力、弱力）。
By calling them “weakly interacting”, physicists mean that the particles experience another of the four fundamental forces, namely, the weak nuclear force that is responsible for radioactive decay.
而且，在弱相互作用重粒子衰变成超级弱相互作用重粒子过程中，应该产生光子和电子等副产品，并且这些粒子也会与质量较轻的原子核发生碰撞，将它们撞碎。
In addition, the decay from WIMP to super-WIMP should have produced photons or electrons as a by-product, and these particles can smash into light nuclei and break them apart.
