QED+QCD Corrections to the Anomalous Magnetic Moment of the Muon [PDF]

, 2021
The current 3:7 discrepancy between experimental and Standard Model determinations of the anomalous magnetic moment has long stood without resolution.

High-precision QED calculations of the hyperfine structure in hydrogen and transition rates in multicharged ions [PDF]

, 2006
Studies of the hyperfine splitting in hydrogen are strongly motivated by the level of accuracy achieved in recent atomic physics experiments, which yield finally model-independent informations about nuclear structure parameters with utmost precision ...

Coulomb corrections for coherent neutrino nucleus scattering

Journal of High Energy Physics
In this work we consider sub-leading O(Z 2 α 3) corrections to coherent elastic neutrino nucleus scattering (CEvNS). These corrections are not negligible by power counting since nuclei with large coherent cross sections have sizeable nuclear charges e.g.

Structure-dependent QED in B − → ℓ − ν ¯ γ $$ {B}^{-}\to {\ell}^{-}\overline{\nu}\left(\gamma \right) $$

Journal of High Energy Physics
Based on explicitly gauge invariant interpolating operators we compute complete next-leading order QED-corrections for leptonic decays. These are sizeable since the helicity-suppression in V-A interactions allows for structure-dependent collinear logs ...

Combining QED and approximate ${\rm N}^3$LO QCD corrections in a global PDF fit: MSHT20qed_an3lo PDFs

SciPost Physics
We present the MSHT20qed_an3lo parton distribution functions (PDFs). These result from the first global PDF analysis to combine QED and approximate $N^3$LO (a$N^3$LO) QCD corrections in the theoretical calculation of the PDF evolution and cross sections ...

The photon content of the neutron

Journal of High Energy Physics
In this work, we complete our CT18qed study with the neutron’s photon parton distribution function (PDF), which is essential for the nucleus scattering phenomenology. Two methods, CT18lux and CT18qed, based on the LUXqed formalism and the DGLAP evolution,

Analytical solution for QCD $$\otimes $$ ⊗ QED evolution

European Physical Journal C: Particles and Fields
We present an analytical solution for the evolution of parton distributions incorporating mixed-order QCD $$\otimes $$ ⊗ QED corrections, addressing both polarized and unpolarized cases.

QED calculations of the 2p-2s transition energies in Li-like ions [PDF]

Systematic QED calculations of ionization energies of the 2s , 2p1/2, and 2p3/2 states as well as the 2p1/2–2s and 2p3/2–2s transition energies are performed for Li-like ions with the nuclear charge numbers Z=10–100 .

QCD+QED simulations with C* boundary conditions [PDF]

Es gibt im Allgemeinen zwei Paradigmen für Entdeckungen in der Teilchenphysik: direkte und indirekte Suchen. Direkte Suchen zielen darauf ab, klare Signale für vermutete Phänomene zu finden, während indirekte Suchen nach Abweichungen zwischen ...
