Quantum Corrections to the Decay Law in Flight
D. F. Ramírez Jiménez, A. F. Guerrero Parra, N. G. Kelkar +1
The deviation of the decay law from the exponential is a well known effect of quantum mechanics. Here we analyze the relativistic survival probabilities, , where is the…
Different manifestations of S-matrix poles
D. F. Ramírez Jiménez, N. G. Kelkar
Making use of the analytical properties of the -matrix and a theorem of Mittag-Leffler, model independent non-relativistic expressions for cross sections in single channel elast…
Extraction of the proton charge radius from experiments
N. G. Kelkar, T. Mart, M. Nowakowski
Static properties of hadrons such as their radii and other moments of the electric and magnetic distributions can only be extracted using theoretical methods and not directly measu…
Inside the Hydrogen Atom
M. Nowakowski, N. G. Kelkar, D. Bedoya Fierro +1
We apply the non-linear Euler-Heisenberg theory to calculate the electric field inside the hydrogen atom. We will demonstrate that the electric field calculated in the Euler-Heisen…
Lorentz Contracted Proton
D. Bedoya Fierro, N. G. Kelkar, M. Nowakowski
The proton charge and magnetization density distributions can be related to the well known Sachs electromagnetic form factors through Fourier transforms, onl…
Determining the size of the proton
N. G. Kelkar, F. Garcia Daza, M. Nowakowski
A measurement of the Lamb shift of 49,881.88(76) GHz in muonic hydrogen in conjunction with theoretical estimates of the proton structure effects was recently used to deduce an acc…
