10−44 5.4?10-20 ys = 5.4?10-44 s: One Planck time tP = ≈ 5.4?10-44 s,[1] the time required for light to travel one Planck length, is the briefest physically meaningful span of time. It is the unit of time in the natural units system known as Planck units. 10−20 ys, 10−19 ys (10−44 s, 10−43 s)
10−24 1 yoctosecond ys[2] Yoctosecond, (yocto- + second), is one septillionth (short scale) of a second. 0.3 ys: mean life of the W and Z bosons.[3][4][a]
0.5 ys: time for top quark decay, according to the Standard Model.
1 ys: time taken for a quark to emit a gluon.
23 ys: half-life of 7H. 1 ys and less, 10 ys, 100 ys
10−21 1 zeptosecond zs Zeptosecond, (zepto- + second), is one sextillionth (short scale) of one second. 7 zs: half-life of helium-9's outer neutron in the second nuclear halo.
