After being created in a high-energy particle accelerator, a pi meson at rest has an average lifetime of 2.60 10-8 s. Traveling at a speed very close to the speed of light, a pi meson travels a distance of 127 m before decaying. How fast is it moving? (Enter your answer to four significant figures.)

1) Muons naturally decay with a half-life of 1.52 μs, meaning that if Mo muons are created at t'=0, then vo will survive at time t 1.52 us as measured by their 'internal clock'. The population N actually decays exponentially according to N(t')=Mo exp(-t σ), where σ=2.2,s. Assume that muons are created in a laboratory and accelerated to essentially the speed of light (a wee bit slower, of course!) in a time much shorter than their half-life. The muons then...

An η meson, whose rest energy is 548 MeV, is moving in the Lab frame with a total energy of 685 MeV in the +x-direction. It decays into two photons a) What is the momentum of the n before the decay? b) What is the velocity of the n before the decay? c) Given that one of the photons is detected going in the +x-direction (this is one of many possible scenarios), find its energy and the energy and direction...

The Σ− Particle The Σ− is an exotic particle that has a lifetime (when at rest) of 0.15 ns. Part A How fast would it have to travel in order for its lifetime, as measured by laboratory clocks, to be 0.28 ns ? Express your answer using two significant figures. v = c
Muons are unstable subatomic particles that decay to electrons with a mean lifetime of 2.2 μs...
Muons are unstable subatomic particles that decay to electrons with a mean lifetime of 2.2 μs . They are produced when cosmic rays bombard the upper atmosphere about 12.4 km above the earth's surface, and they travel very close to the speed of light. The problem we want to address is why we see any of them at the earth's surface. a) What is the greatest distance a muon could travel during its 2.2 μs lifetime? b) According to your...
