A certain process produces mesons that decay with a lifetime of 6 *10^-¹⁰ s. The decay is a result of:

Question

Quizplus · Accepted Answer

The fact that the mesons decay with a lifetime of 6 × 10-10 s indicates that the weak interaction is involved, as this is the timescale over which weak decays typically occur. The other interactions (gravitational, electromagnetic, and strong) do not occur on such short timescales and cannot explain the meson decay.
