Weinberg Angle, Neutron Abundance in BBN, and Lifetime
Cheng Tao Yang, Johann Rafelski
We present state of the art kinetic theory determination of the neutron abundance available for the Big-Bang nucleosynthesis (BBN). Our work is motivated by the study of the neutro…
Comment on "All-Loop Result for the Strong Magnetic Field Limit of the Heisenberg-Euler Effective Lagrangian"
Stefan Evans, Johann Rafelski
We offer a 2nd look at the recently claimed improvement of Euler-Heisenberg-Schwinger (EHS) action [PRL \textbf{122} (2019) no.21, 211602 and post-publication correction]: We demon…
Everlasting interaction: polarization summation without a Landau pole
Stefan Evans, Johann Rafelski
We propose an external field approach to evaluating effective action allowing the interaction to act everywhere at all times (everlasting). Requiring that the asymptotic gauge fiel…
Non-perturbative Analysis of the Influence of the Proton Magnetization and Charge Densities on the Hyperfine Splitting of Muonic Hydrogen
J. D. Carroll, A. W. Thomas, G. A. Miller +1
We investigate the influence of the spatial extent of the proton magnetization and charge densities on the 2S hyperfine splitting in muonic hydrogen. The use of a non-perturbative…
Natural Resolution of the Proton Size Puzzle
G. A. Miller, A. W. Thomas, J. D. Carroll +1
We show that off-mass-shell effects arising from the internal structure of the proton provide a new proton polarization mechanism in the Lamb shift, proportional to the lepton mass…
Quark Condensate and Effective Action from Dyson--Schwinger Equations
A. V. Zayakin, V. Khandramai, J. Rafelski
We obtain the QCD quark condensate from consideration of unquenched quark dynamics in Dyson-Schwinger gluon vacuum. We consider the non-local extension of the condensate and determ…
