We compute the standard Euclidean window of hadronic vacuum polarization using multiple independent blinded analyses. improve continuum and infinite-volume extrapolations dominant quark-connected light-quark isospin-symmetric contribution address additional subleading systematic effects from sea-charm quarks residual chiral-symmetry breaking first principles. find ${a}_{\mathrm{\ensuremath{\mu}}}^{\mathrm{W}}=235.56(65)(50)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}10}$, which is in $3.8\ensuremath{\sigma}$ tension with recently published dispersive result ${a}_{\mathrm{\ensuremath{\mu}}}^{\mathrm{W}}=229.4(1.4)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}10}$ [G.

Hadronic Vacuum Polarization and the Lamb Shift
Recent improvements in the determination of the running of the fine-structure constant also allow an update of the hadronic vacuum-polarization contribution to the Lamb shift. We find a shift of −3.40(7) kHz to the 1S level of hydrogen. We also comment on the contribution of this effect to the determination by elastic electron scattering of the r.m.s. radii of nuclei.
متن کاملHadronic Vacuum Polarization Contribution to the Muonium Hyperfine Splitting
We discuss hadronic effects in the muonium hyperfine structure and derive an expression for the hadronic contribution to the hfs interval in form of the onedimensional integral of the cross section of e+e− annihilation into hadrons. Higherorder hadronic contributions are also considered.
متن کاملEuclidean Windows
In this paper we study number fields which are Euclidean with respect to a function different from the absolute value of the norm. We also show that the Euclidean minimum with respect to weighted norms may be irrational and not isolated.

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
