Complete next-to-next-to-leading order QCD corrections to the decay matrix in -meson mixing at leading power
Ulrich Nierste, Pascal Reeck, Vladyslav Shtabovenko +1
We compute next-to-next-to-leading order corrections to the decay width difference of mass eigenstates and the charge-parity (CP) asymmetry in flavour-specific decays…

Current-current operator contribution to the decay matrix in -meson mixing at next-to-next-to-leading order of QCD
Marvin Gerlach, Ulrich Nierste, Pascal Reeck +2
We compute next-to-next-to-leading order perturbative corrections to the decay width difference of mass eigenstates and the charge-parity asymmetry in flavour-specific…

Kaon Physics: A Cornerstone for Future Discoveries
Jason Aebischer, Atakan Tugberk Akmete, Riccardo Aliberti +153
The kaon physics programme, long heralded as a cutting-edge frontier by the European Strategy for Particle Physics, continues to stand at the intersection of discovery and innovati…
