Muon Decay By Bye Bye Miss American Pions newbooksinbrief.com www.scienceinschool.org www.alternativephysics.org Our Experiment The Scintillator Scintillator Scintillation detector Theory of Poisson Decay dp =λdt given Dp = Probability that the muon will decay λdt P(0,dt) = (1-λdt) Probability that the muon won’t decay What is the probability that the muon has not decayed by the time t + dt ? What is the probability that the muon has not decayed by the time t + dt ? At time dt decay won’t happen P(0,dt) At time t decay won’t happen P(0,t) 1-p 1-p At time dt decay won’t happen P(0,dt) = t + dt P(0,dt) At time t decay won’t happen P(0,t) P(0,t) X p(0,dt) P(0,t+dt) = p(0,t)x p(0,dt) 1-p = p(0,t)(1-λdt) 1-p Won’t happen Now we know the probability that muon decay won’t happen which is p(0,t)(1-λdt) P(0,t+dt) = P(0,t)- λdtp(0,t) P(0,t+dt) - P(0,t) = - λdtp(0,t) P(0,t+dt)− P(0,t) = - λ 𝑃 0, 𝑡 𝑑𝑡 Rearrangement making - λ 𝑃 0, 𝑡 subject P(0,t+dt)− P(0,t) 𝑑𝑝(0,𝑡) = 𝑑𝑡 𝑑𝑡 𝑑𝑝 = −λ𝑝 𝑑𝑡 Integration 1 Dp(0,t) 𝑝(0,𝑡) = −λ𝑑𝑡 𝑑𝑡 = 1𝑋𝑑𝑡 𝑡 0 𝑑𝑡 P(0,t) = -λt + c P(0,t) = 𝑒 −λt + c P(0,t) = 𝑒 −λt + c = 1 0 = -λt + c c= λt t+c P(0,t) = 1 Substitute c= λt into P(0,t) = 𝑒 −λt + c P(0,t) = e^-λ(t + t1) So why do we care? 6 km 0.994c = 2.01x10-5s 20.1µs > http://www.deepscience.org/contents/summary.shtml 2.2µs Time Dilation 2d t= c http://www.astronomyforum.net/astrophysics-forum/133179-cause-gravitational-time-dilation.html http://hyperphysics.phy-astr.gsu.edu/hbase/relativ/tdil.html 2b t= c Thank you for listening
