## A Brief Discussion on Participation of \mu-mesons (muons) based upon Relativistic Dynamics

 The life time of muons { $\mu$-mesons } is $2.2 \times 10^{-6}$ seconds and their speed $0.998c$, so that they can cover only a distance of $0.998c \times 2.2 \times 10^{-6}$ or 658.6 meters in their entire lifetime, and yet they are found in profusion at sea level, i.e., at a depth of 10 kilometers from the upper atmosphere where they are produced. How may this be explained on the basis of (i) Lorentz – Fitzgerald Contraction; (ii) Time Dilation.
