Muons. They live thousands of times longer than
their otherwise identical cousins that move more slowly.
Things have moved on since 1918. Don;t tell me you
too are "stuck in the past"?

Muons couple to their surroundings with a force
10,000,000,000,000,000,000,000,000,000,000 times

the force that gives the components of your watch
some inertia.

A rubber ducky in you bathtub is closer to the
QE II for comparisons sake.

That isn't an answer. They couple similarly to a proton. No
"new physics" there either.

They are coupled to accelerator magnets rather than
to Stella's wrist watch.

Ya know what is really strange? The half life is proportional to the
apparent velocity in the storage ring, NOT the field strength of the
magnets of the accelerator. Seems like if it depended on the coupling,
it would be proportional to the magnets field strength, wouldn't it?

In the case of accelerators light is more a motive tool
than an observational tool. A hockey puck doesn't know
the muzzle velocity of a rifle. But if you are accelerating
the puck by shooting at it, it will *appear* to have a top
speed equal to the muzzle velocity of the rifle.



In fact, I bet that if I used a very strong em field to 'trap' the
muons but don't make them run around in circles, they don't live any
longer than their brothers that never are subject to the magnetic
field.

Guessing how muons behave is certainly easier than
reading about them.

Congratulations, once again you succeed in finding an article that is
almost totally unrelated to the subject in question.

This dissertation describes an experiment which measured the inclusive
production of muons with momenta greater than 1.6 GeV/c in multihadron
events in e('+)e(' -) interactions in the center of mass energy range 12.0
-31.6 GeV. The experiment was performed at the positron -electron storage
ring PETRA at the Deutsches Elektronen -Synchrotron Lab in Hamburg, West
Germany. The apparatus used was the PLUTO detector which is a general-
purpose magnetic detector with essentially complete coverage for charged
particles, photons and leptons. Muon identification was achieved by an
approximately one meter thick mostly steel absorber, with arrays of planar
drift chambers outside the absorber to detect penetrating particles. In the
center of mass energy range 12.0-31.6 GeV, the measured inclusive muon
production cross section is found to be consistent with a source of muons
coming from semi-muonic decay of charm and bottom mesons produced in e('+)e
('-) annihilation. The larger muon production cross section expected from
production and semi-muonic decay of top mesons in the standard model is not
observed. The momentum spectrum of the muons was also measured for momenta
greater than 1.6 GeV/c and is found to agree with predictions of the charm
and bottom decay model. A search for a new charged lepton heavier than the
tau was also performed. In the center of mass energy range 29.9-31.6 GeV,
no multihadron event with an isolated muon which can be attributed to the
production and muonic decay of a new heavy lepton was found. A new charged
sequential heavy lepton in the mass range 7-14 GeV/c('2) is excluded at 95%
CL.

There is no sign that they observed anomalous muon half lifetimes.

Would "stopped" muons work as well as "trapped" muons?

<< During a 5 s ``fill period'', muons are directed to a thin
stopping target. A 22 s ``measurement period'' follows with
the beam ``off'' while the stopped muons decay. A spherical
detector surrounding the target detects the decay positrons. >>

Now that cite is closer to being on target but it has the [from your
viewpoint] disadvantage of reinforcing my viewpoint. What they have done is
increase the precision of the half life measurement.

Following recent theoretical calculations, the uncertainty on the Fermi
coupling constant is now limited by the precision with which the muon
lifetime is measured. The current world average uncertainty on the lifetime
is 17 ppm. The MuLan experiment is designed to measure the muon lifetime to
1 ppm. To supply muons, a periodic, pulsed muon beam is created. During a 5
µs ``fill period'', muons are directed to a thin stopping target. A 22 µs
``measurement period'' follows with the beam ``off'' while the stopped
muons decay. A spherical detector surrounding the target detects the decay
positrons. A wire chamber with a 10 x10 cm window is used during beam
tuning and for regular measurements during data production. An FPGA is used
to enable fast readout of the wire chamber. The firmware that controls the
FPGA allows for prescaling during the fill period to reduce the data rate.
A number of scalar signals are produced that reflect the flux of muons in
specific areas of the chamber. This firmware is currently being used in the
2006 data production run. I have been responsible for the FPGA firmware, as
well as various analysis studies.

Would you like to try again to cite something that actually supports what
you have been saying?


Ah, but Caesar was an honorable man and Sue never is wrong.

I was wrong when I predicted you would give up on the
absurd twins myth within a year. :-(

"The [ ] Incompatibility of the Law of Propagation of
Light with the Principle of Relativity [is only] Apparent"
http://www.bartleby.com/173/7.html


So 'light always travels at c' is compatable with 'the priciple of
relativity'. SR rules [within its domain]. What else is new? Why do you
continue to cite that quotation as if it showed a problem with SR?

Einstein changed his explanation of the differential aging from that in the
1905 paper but I do not see anywhere that he abandoned the differential
aging.

I have yet to see you present ANY evidence that stationary muons live just
as long as traveling muons or that the traveling twin will have just as
many gray hairs (and show the same amount of aging on a cellular level) as
the stay at home twin.
