ISR corrections to associated HZ production at future Higgs factories
Physics Letters B, 2018 We evaluate the QED corrections due to initial state radiation (ISR) to associated Higgs boson production in electron–positron (e+e−) annihilation at typical energies of interest for the measurement of the Higgs properties at future e+e− colliders, such ...

Scalar QED, NLO and PHOTOS Monte Carlo [PDF]
, 2006 Recently, due to improvement at experiments, QED bremsstrahlung in B meson decays into pair of scalars (\pi's and/or K's) is of phenomenological interest.

Precision study of positronium and precision tests of the bound state quantum electrodynamics
, 2002 Despite its very short lifetime positronium provides us with a number of accurate tests of the bound state quantum electrodynamics (QED). In this note a brief overview of QED theory and precision experiments on the spectrum and annihilation decay of the ...

Precision test of bound-state QED at intermediate Z with kaonic neon
We report Dirac-Fock calculations of transition energies for kaonic neon (KNe). For the most in- tense line, the 7–6 transition, the calculated energy is 9450.28 eV, which includes a bound-state QED (BSQED) contribution of 12.66 eV.

Threshold corrections in QED x QCD at the LHC
, 2004 In some processes at the LHC, theoretical precisions of 1 percent are desired. With an eye toward such precisions, we introduce the theory of the simultaneous YFS resummation of QED and QCD to compute the size of the expected resummed soft radiative ...

Combining QED and QCD transverse-momentum resummation for Z boson production at hadron colliders
Journal of High Energy Physics, 2018 We consider the transverse-momentum (q T ) distribution of Z bosons produced in hadronic collisions. At small values of q T , we perform the analytic resummation of the logarithmically enhanced QED contributions up to next-to-leading logarithmic accuracy,

Coulomb corrections for coherent neutrino nucleus scattering
Journal of High Energy PhysicsIn 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.

Cavity QED with Multilevel Atoms [PDF]
, 2005 The steady-state transmission spectrum of a cavity with two modes of orthogonal polarization strongly coupled to a single atom with multiple Zeeman states is computed. Effects due to cavity birefringence and atomic ac-Stark shifts are included.
