Bound-state decay of a charged scalar particle in an external Coulomb field
Andrzej Czarnecki, Artem O. Davydov
We determine the decay rate of a scalar particle bound to a light nucleus, numerically and analytically. As a model system, we consider a negatively charged kaon in the ground…
Radiative Corrections in Bound States: Recent Results
Andrzej Czarnecki, Artem O. Davydov
Two recent studies of radiative corrections to bound state properties are discussed. The change of the decay rate of a muon bound to a light nucleus has been calculated for several…
Parapositronium decay into three photons and implications for the neutral pion
Andrzej Czarnecki, Divyesh Dagia, Ting Gao +1
We complete the determination of the parapositronium decay into three photons by evaluating amplitudes mediated by the boson. We show that, contrary to the expectation that the…
Total decay rate of a muon bound to a light nucleus
Andrzej Czarnecki, A. O. Davydov, M. Y. Kaygorodov
We revisit the total decay rate of a muon being in the ground state of a Coulomb potential with atomic charge numbers . The discrepancy between the perturbative $(α…
Hidden Momentum and the Absence of the Gravitational Spin Hall Effect in a Uniform Field
Andrzej Czarnecki, Ting Gao
We re-examine the recent claim that a Dirac particle freely falling in a uniform gravitational field exhibits a spin-dependent transverse deflection (gravitational spin Hall effect…
Spin in Uniform Gravity, Hidden Momentum, and the Anomalous Hall Effect
Andrzej Czarnecki, Ting Gao
We review the recent discussion of the absence of spin Hall effect in a uniform gravitational field, pointing out differences from the anomalous spin Hall effect in ferromagnetics…
The anomalous magnetic moment of the muon in the Standard Model: an update
R. Aliberti, T. Aoyama, E. Balzani +232
We present the current Standard Model (SM) prediction for the muon anomalous magnetic moment, , updating the first White Paper (WP20) [1]. The pure QED and electroweak contrib…
Thomas precession, relativistic torque, and non-planar orbits
Andrzej Czarnecki, Andrei Zelnikov
We analyze the angular momentum balance for a particle undergoing Thomas precession. The relationships among relativistic torque, the center of mass, and the center of inertia for…
