Workshop summary: Kaons@CERN 2023
/ Anzivino, G. (INFN, Perugia ; Perugia U.) ; Cuendis, Sergio Arguedas (Costa Rica U.) ; Bernard, V. (IJCLab, Orsay) ; Bijnens, J. (Lund U.) ; Bloch-Devaux, B. (Turin U.) ; Bordone, M. (CERN) ; Brizioli, F. (INFN, Perugia ; CERN) ; Brod, J. (Cincinnati U.) ; Camalich, J.M. (IAC, La Laguna ; Laguna U., Tenerife) ; Ceccucci, A. (CERN) et al.
Kaon physics is at a turning point -- while the rare-kaon experiments NA62 and KOTO are in full swing, the end of their lifetime is approaching and the future experimental landscape needs to be defined. With HIKE, KOTO-II and LHCb-Phase-II on the table and under scrutiny, it is a very good moment in time to take stock and contemplate about the opportunities these experiments and theoretical developments provide for particle physics in the coming decade and beyond.

Al (Oxford U.) et al.
The nature of dark matter and properties of neutrinos are among the most pressing issues in contemporary particle physics. The dual-phase xenon time-projection chamber is the leading technology to cover the available parameter space for Weakly Interacting Massive Particles (WIMPs), while featuring extensive sensitivity to many alternative dark matter candidates.

Mounting Evidence for the Violation of Lepton Flavor Universality
/ Crivellin, Andreas (Zurich U. ; PSI, Villigen ; CERN) ; Hoferichter, Martin (Bern U.)
The Standard Model (SM) of particle physics was finalized in its current form in the mid-1970s, and has been extensively tested and confirmed ever since, with the discovery of the Higgs boson in 2012 being the last missing piece. While no new particles have been directly discovered at the Large Hadron Collider (LHC) at CERN so far, precision observables sensitive to quantum effects of new particles have accumulated intriguing hints for physics beyond the SM. [...]

First-Generation New Physics in Simplified Models: From Low-Energy Parity Violation to the LHC
/ Crivellin, Andreas (Zurich U. ; PSI, Villigen ; CERN) ; Hoferichter, Martin (Bern U. ; U. Bern, AEC) ; Kirk, Matthew (Rome U. ; INFN, Rome) ; Manzari, Claudio Andrea (Zurich U. ; PSI, Villigen) ; Schnell, Luc (Paris, LPTHE ; Zurich, ETH ; Ec. Polytech., Palaiseau (main))
New-physics (NP) constraints on first-generation quark-lepton interactions are particularly interesting given the large number of complementary processes and observables that have been measured. Recently, first hints for such NP effects have been observed as an apparent deficit in first-row CKM unitarity, known as the Cabibbo angle anomaly, and the CMS excess in $q\bar q\to e^+e^-$. [...]
