Cosmic Ray Muon Production Altitude is not right! Hi there, I wrote a Programm to calculate the cosmic ray muon intensity on different altitudes. I dedicated this programm from the intensity of the primary cosmic rays and the intercations in the atmosphere. First a Proton with the Energy...

I am looking at muons being lost as they travel through a concrete bunker (with various things inside). The minimum energy (mean) for a muon to go through the walls is about 1.82GeV, and for the stuff inside (flakes of magnesium) it is 2.7GeV. For a piece of heavy metal it is 0.13GeV (it's...

The muon energy loss equation (at high energies) is: -dE/dx = a(E) + b(E)E where a(E) represents the ionization losses (Bethe equation), and b(E) represents radiative losses (bremsstrahlung, pair production, photo-nuclear). From what I have read, at high energies for high-Z materials...

I have been looking at the flux of muons (as secondary cosmic ray particles) at the Earth's surface as a function of both energy and angle from the zenith. From what I have read, the flux follows a squared cos theta relationship with angle from the zenith and several attempts have been made to...

A muon is observed to travel 800 meters before disintigrating. The lifetime of a muon is 2 * 10 ^ -6. So the observer concludes that the muon traveled at a speed of 4 * 10^8 m/s which is faster than c. Why is the observer wrong? I though it was impossible for anything to travel faster...

Homework Statement a muon moving in a straight line enters a region w/ speed of 5 x 10^6 m/s. it then slowed down at a rate of 1.25 m/s^2. how far does the muon take to stop?? Homework Equations 2ad + square of initial velocity = square of final velocity The Attempt at a...

Hallo everybody! Is there anybody dealing with CMS stuff? Let's share infos here, and let's discuss the stuff related to Compact Muon Solenoid experiment simulations. I am a student, and have to work on H-->2mu ee- (Higgs to muon+ muon- electron positron) Plz, leave here any related...

free neutrons are unstable: would a muon in say uranium be "stable"? free neutrons are unstable: would a muon in say uranium be "stable"? free neutrons decompose and have a half-life of about 15 minutes. neutrons bound in a nucleus, especially in a magic shell configuration like helium-4 or...

I was actually pondering the existence of modern electronics, and the ability of a magnetic generator which applies a force to move electrons in a copper wire. As another energy source is used to turn the turbine (e.g coal, fuel - combustion, nuclear), the magnets apply a electromagnetic force...

The positive pion decays into a muon and a neutrino. The pion has rest mass m_\pi , the muon has m_\mu , while the neutrino has m_v = 0. Assuming the original pion was at rest, use conservation of momentum and energy to show that the speed of the muon is given by: \frac{u}{c} = \frac{...

A few years ago BNL did some experiments measuring muon g-2. At the time there was a significant enough difference from the calculations based on the Standard Model to raise questions about SM. Since then I've seen papers indicating that SM was probably OK, with the discrepancy being due to...

I'm speaking of the Muon decay experiment which showed no additional gravitationally related time effects in a centrifuge... Firstly does anyone have a real reference for the experiment? All I find are offhand mentions of it. The only identifying info I've gotten on it was that it was in 1966...

I've been doing some research on Muon spectroscopy, and am not that far in the physics world yet. I've got kind of a fuzzy picture of what goes on, but could use some help in identifying some key concepts. The information I have been getting is from the following paper Muon-Spin Rotation...

The electron in the Hydrogen atom can be replaced by the heavier muon resulting in a muonic atom. The muonic atom is not stable because the muon lives for 2.2 ms on average and then it decays into an electron and two neutrinos. However some very fast experiments can be performed on the muonic...

Need HELP! Muon Lifetime Experiment I just recently collected data from a muon lifetime determination experiment. The data was presented in the form of two columns: x = time (microseconds) and y = counts/bin. After plotting this xy into a graph I found that my muon lifetime was 2.12 (close...

How are the electron neutrino, the muon neutrino and the tau neutrino different from each other (except for the leptonic number they carry)? I heard they BEHAVE like their associated Lepton (el., muon, tau). If so, in what way? Thanks.

I am new to this matter, but I was reading a problem about how as the muon travels at .98c, that it's half life is increased by an approximate factor of 5. What I have trouble with is when using the Lorentz transform, why time dilation is calculated in the moving system at the same X and V...

i have a question i have to do this problem i know somewhat how it sets up but what do u take from the initial condition? do u take the distance the muon travels? can someone help me set this bad boy up Suppose a muon produced as a result of a cosmic ray colliding with a nucleus in the...
