    Graduate Self-Adjointness on Differential Equations

    "Self-Adjointness" on Differential Equations Hey, I am just wondering why is that we always try to look for self-adjoints Differential Equations. I mean I know the advantages of having self-adjoint operators, i.e, they have real eigenvalues, eigenfunctions are orthogonal and form a complete...

    Graduate Compute Breit-Wigner for particle decay

    OK, that's what I meant by "disappear", sorry the non-technical term. And you are right, it gets squared so that i^2 = -1 and the final result is real which corresponds to the "magnitude" of the complex number.

    Graduate Compute Breit-Wigner for particle decay

    OK I gave it a second thought and I got it, that BW (for that decay) appears inside a function which is squared, so the imaginary part actually disappears, should have seen this before posting heh, sorry.

    Graduate Compute Breit-Wigner for particle decay

    Hey, I am just woondering if anyone here have computed (numerically) the Breit-Wigner for a particle decay. I have to do some nonlinear fitting of data but I need to compute this, any ideas? My case is specific, and I am brand new to particle physics, it's for a tau decay into Kaon, pion and...
