Phenomenology of matching exponentiated photonic radiation to a QED-corrected parton shower in KKMChh [PDF]

Proceedings of 42nd International Conference on High Energy Physics — PoS(ICHEP2024)
KKMChh is a precision Monte Carlo program for photonic and electroweak radiative corrections to hadron scattering, implementing the amplitude-level exponentiation originally developed for electron-positron scattering at the quark level, modeling initial ...

Deterministic Integration of Quantum Emitters and Optical Cavities in a Van Der Waals Crystal

Advanced Optical Materials, Volume 14, Issue 31, August 21, 2026.
The work demonstrates fabrication of Circular Bragg Grating (CBG) cavities with embedded emitters in hBN. The cavities are fabricated around a pre‐characterised quantum emitter. The integrated platform enables light matter interaction and access to brighter emitters and spins in hBN.

Transverse-momentum resummation at mixed QCD⊗QED NNLL accuracy for Z boson production at hadron colliders

Journal of High Energy Physics
We consider the transverse momentum (q T ) distribution of neutral charged bosons at hadron colliders. We perform the resummation of the logarithmically-enhanced effects due to simultaneous QCD and QED initial-state radiation, up to mixed next-to-next-to-

Muonic-Atom Spectroscopy and Impact on Nuclear Structure and Precision QED Theory

, 2022
Recent progress in laser and x-ray spectroscopy of muonic atoms offers promising long-term possibilities at the intersection of atomic, nuclear and particle physics. In muonic hydrogen, laser spectroscopy measurements will determine the ground-state hyperfine splitting (HFS) and additionally improve the Lamb shift by a factor of 5.

The Gamma Factory: A New Experimental Paradigm for the Post‐HL‐LHC Era

Annalen der Physik, Volume 538, Issue 8, August 2026.
ABSTRACT The Gamma Factory (GF) proposal is motivated by the recognition of a largely untapped potential of the CERN accelerator complex to enable a new research program at the intersection of particle, nuclear, atomic, fundamental, and applied physics. These fields could benefit from novel experimental tools made possible by a future GF facility.

One-Particle Operator Representation over Two-Particle Basis Sets for Relativistic QED Computations. [PDF]

Journal of Chemical Theory and Computation
This work is concerned with two-spin-1/2-fermion relativistic quantum mechanics, and it is about the construction of one-particle projectors using an inherently two-particle, "explicitly correlated" basis representation necessary for good numerical ...

Towards a precise determination of the order of the phase transition in compact pure gauge QED

Physics Letters B, 1990
Abstract We present results obtained with a new numerical method, which in principle allows to determine the partition function of a lattice gauge theory, and its derivatives, with an accuracy dictated only by statistical fluctuations. We have used this method in order to determine the order of the phase transition of pure gauge, compact QED and we ...
