Dark light shining on
Patrick D. Bolton, Jernej F. Kamenik, MartÃn Novoa-Brunet
Recent Belle II data on show an excess consistent with a two-body decay involving a light invisible particle with mass around . We pre…
Impact of new invisible particles on observables
Patrick D. Bolton, Svjetlana Fajfer, Jernej F. Kamenik +1
Motivated by a recent Belle~II measurement that suggests an excess in the rare decay , and building upon our recent differential decay rate likelihood analy…
Physics Briefing Book: Input for the 2026 update of the European Strategy for Particle Physics
Jorge de Blas, Monica Dunford, Emanuele Bagnaschi +127
The European Strategy for Particle Physics (ESPP) reflects the vision and presents concrete plans of the European particle physics community for advancing human knowledge in fundam…
Flavor Physics at the CEPC: a General Perspective
Xiaocong Ai, Wolfgang Altmannshofer, Peter Athron +147
We discuss the landscape of flavor physics at the Circular Electron-Positron Collider (CEPC), based on the nominal luminosity outlined in its Technical Design Report. The CEPC is d…
Signatures of Light New Particles in
Patrick D. Bolton, Svjetlana Fajfer, Jernej F. Kamenik +1
The recent Belle II observation of challenges theoretical interpretations in terms of Standard Model neutrino final states. Instead, we consider new physics…
Ultra High Energy Cosmic Rays versus Models of High Energy Hadronic Interactions
Blaž Bortolato, Jernej F. Kamenik, Michele Tammaro
We evaluate the consistency of hadronic interaction models in the CORSIKA simulation package with publicly available fluorescence telescope data from the Pierre Auger Observatory.…
