Thus, the lifetime of a particle is the direct inverse of the particle's resonance width. For example, the charged pion has the second-longest lifetime of any meson, at 2.6033×10^−8 s. Therefore, its resonance width is very small, about 2.528×10−8 eV or about 6.11 MHz. inclination walking treadmill variability
