Forgive my question for being so elementry, but I'm jumping a bit ahead of my curriculum...
I've attached a decay process for the negative pion. I actually spliced together the initial pion decay and then the subsequent muon decay, assuming the entire process is correct.
1) the first W-...
sorry, gamma MUST be always both positive and negative at ANY velocity other than c.
however, zero in the denominator has neither positive or negative values. In fact, it is only at v = c that there is 1 unique solution.
how about this: silly idea, but think about it:
the square root of 1 = {+1,-1}
and we all know: t'=t/(1-(v/c)^1/2)
in essance, t' must simultaneously have values of {+t',-t'} for all velocities not equal to zero and approaching c.
this means that for a relativistic frame of...
there is a super interesting paper on the feynman-stuckelberg interpretation of time symmetry at this local:
http://arxiv.org/ftp/gr-qc/papers/9906/9906012.pdf
I just found thgis - discusses the FS interpretation with respect to general relativity. gets kind of weird.
My gut feeling...
I have been looking around on the web, including this forum, regarding the question: "does a photon experience the passage of time?"
reputable sites, including this one, and quotes from reputable people, seem to disagree.
is the answer, "we don't know?"
the implications of a photon...
1. If I traveled in a wormhole from Earth to a distant star 10 LY away, and arrived there instantly, when would I arrive at the star? Would I be there 10 years ago, as the light took 10 years to reach Earth? If Minkowski space is truly 4D i.e., space-time, then I can't arrive at some...
I've attached a feynman diagram i drew myself because i can't find a proper feyman diagram for this decay. I assume that since the decay K+->u+ + Vu is weak it goes via a W boson.
Is this diagram correct?
thanks
Yes, I saw it in the PDG mesons summary table, albeit without a feynman diagram. The feynman diagram shows everything between the up (at the top of the diagram) and the anti-up (at the bottom) comming from a w+ boson, half of it from a subsequent massive decay from a gluon. Being naive, it...
I'm just a student, but, as far as I know, every process in the universe that we know of relies on the uncertainty principle. there would be none of the four forces, no matter - everything would not exist; the universe woud still be chaos.
