Toward high-precision values of the self energy of non-S states in hydrogen and hydrogen-like ions

, 2004
The method and status of a study to provide numerical, high-precision values of the self-energy level shift in hydrogen and hydrogen-like ions is described. Graphs of the self energy in hydrogen-like ions with nuclear charge number between 20 and 110 are

Quantum GraviElectro Dynamics

Annalen der Physik, Volume 538, Issue 1, January 2026.
The BRST invariant Lagrangian of the gravitationally interacting U(1)$U(1)$ gauge theory, namely the Quantum GraviElectro Dynamics (QGED). The Yan–Mills theory with the Hilbert–Einstein gravitational Lagrangian, namely the Yang–Mills–Utiyama (YMU) theory, is defined and quantised using the standard procedure. The theory is perturbatively renormalisable,

Consequences of chirally enhanced explanations of (g − 2) μ for h → μμ and Z → μμ

Journal of High Energy Physics, 2021
With the long-standing tension between experiment and Standard-Model (SM) prediction in the anomalous magnetic moment of the muon a μ recently reaffirmed by the Fermilab experiment, the crucial question becomes which other observables could be sensitive ...

Precise measurement of positronium hyperfine splitting using the Zeeman effect

, 2011
Positronium is an ideal system for the research of the quantum electrodynamics (QED) in bound state. The hyperfine splitting (HFS) of positronium, $\Delta_{\mathrm{HFS}}$, gives a good test of the bound state calculations and probes new physics beyond ...

TargetGen‐RNN model discovers novel antibiotic compound targeting drug‐resistant Staphylococcus aureus

Interdisciplinary Medicine, Volume 4, Issue 1, January 2026.
TargetGen‐recurrent neural network (RNN), an advanced generative model, generated 28,708 unique and novel compounds, identifying SAK‐2970 as a potent antibiotic against drug‐resistant Staphylococcus aureus. Exhibiting strong biofilm inhibition, high therapeutic efficacy, and minimal systemic toxicity in vivo, SAK‐2970 highlights its safety and clinical

Higher-order Sudakov resummation in coupled gauge theories

Journal of High Energy Physics, 2020
We consider the higher-order resummation of Sudakov double logarithms in the presence of multiple coupled gauge in. The associated evolution equations depend on the coupled β functions of two (or more) coupling constants α a and α b , as well as ...

On the Elusive Ninth Vibrational State of the Argon Dimer

Natural Sciences, Volume 6, Issue 1, January 2026.
ABSTRACT An unresolved discrepancy between high‐accuracy potential energy curves for the argon dimer (Ar2${\rm Ar}_2$), which support different numbers of bound vibrational states and profoundly different scattering lengths for Ar2${\rm Ar}_2$, is probed by morphing these curves to available spectral data within the reduced potential energy curve ...

Isospin mass differences of the B, D and K

Journal of High Energy Physics, 2023
We compute the electromagnetic mass difference for the B-, D- and K-mesons using QCD sum rules with double dispersion relations. For the B- and D-mesons we also compute the linear quark mass correction, whereas for the K the standard soft theorems prove ...

QED corrections to isospin-related decay rates of charged and neutral B mesons

, 2004
We estimate the isospin-violating QED radiative corrections to the charged-to-neutral ratios of the decay rates for B^+ and B^0 in non-leptonic B meson decays.
