Positronium S state spectrum : analytic results at O ( mα
نویسندگان
چکیده
We present an analytic calculation of the O(mα6) recoil and radiative recoil corrections to energy levels of positronium nS states and their hyperfine splitting. A complete analytic formula valid to O(mα6) is given for the spectrum of S states. Technical aspects of the calculation are discussed in detail. Theoretical predictions are given for various energy intervals and compared with experimental results.

متن کاملPositronium hyperfine splitting: analytical value at O(mα6)
We present an analytic calculation of the O(mα6) recoil corrections to the hyperfine splitting (HFS) of the ground state energy levels in positronium. We find ∆Erec = mα 6 ( − 6 lnα+ 331 432 − ln 2 4 − 17ζ(3) 8π + 5 12π )
متن کاملO ( α 3 ln α ) corrections to muonium and positronium hyperfine splitting
The perturbative series for binding energies of a QED bound state are non-analytic in the fine structure constant and the expansion contains powers of α1 ln2 α, where n1 and n2 are some integer numbers. The appearance of logarithms of α is best explained by the fact that different scales, such as the mass m, the momentum mα and the typical energy mα control dynamics of the bound state. In a rec...
متن کاملAnalytic Treatment of Positronium Spin Splittings in Light-Front QED
We study the QED bound-state problem in a light-front hamiltonian approach. Starting with a bare cutoff QED Hamiltonian, H B , with matrix elements between free states of drastically different energies removed, we perform a similarity transformation that removes the matrix elements between free states with energy differences between the bare cutoff, Λ, and effective cutoff, λ (λ < Λ). This gene...
متن کاملLight-front Hamiltonian Approach to the Bound-state Problem in Quantum Electrodynamics
This dissertation presents the first theoretical investigation of the Lamb shift in a light-front hamiltonian approach: the dominant part of the splitting between the 2S 1 2 and 2P 1 2 energy levels in hydrogen is calculated. Also presented for the first time is an analytic calculation in a light-front hamiltonian approach of the singlet-triplet spin splitting in the ground state of positronium...
