So, the common leptonic decay channels for the K^{+/-} is the two quarks annhilating into a W^{+/-} which then decays into whatever electron/muon neutrino pair. What's confusing me is that the K^{+/-} is J=0 but the intermediate W is J=1. Is the answer to give the W one unit of orbital angular...
Imaginary components to the potential can be useful, though. If you look at the time evolution of the wavefunction, you'll notice that the probability is no longer conserved, which can be used to describe a particle in a decaying state, i.e. leaving the system described by your hamiltonian.
Serway's "College Physics" gives a good start that is algebra based and runs across all of the materials covered in the first two semesters of a typical freshman physics course.
If you're interested in something more advanced, have a look at college courses homepage and see what texts are...
Both particles are mathematically described to go forward in time. The law that disallows it to even be mathematically represented "going backwards" is the necessity for positive kinetic energies.
Look at solutions to the Dirac equation for the physical solutions for the electron and...
There will never be any time difference to the observer. The only time difference that will be measured will be from the person sitting in your "absolute frame of reference". Everyone in other frames will get different time differences and they will all think they are in what you claim to be...
Convergence
Can it be proven the Laplace transform of Pi(x) even exists (i.e. converges)? If it can't be done rigorously nothing after (2) is valid. Furthermore, you really don't want to do an approximation if you want to find integers.
On top of that, did you use your method to do what it...
