Review of particle physics
/ Particle Data Group Collaboration
The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 2,717 new measurements from 869 papers, we list, evaluate, and average measured properties of gauge bosons and the recently discovered Higgs boson, leptons, quarks, mesons, and baryons [...]

Focus topics for the ECFA study on Higgs / Top / EW factories
/ de Blas, Jorge (Granada U.) ; Koppenburg, Patrick (Nikhef, Amsterdam) ; List, Jenny (DESY) ; Maltoni, Fabio (Louvain U.) ; Maestre, Juan Alcaraz (Madrid, CIEMAT) ; Alimena, Juliette (DESY) ; Alison, John (Carnegie Mellon U.) ; Azzi, Patrizia (INFN, Padua) ; Azzurri, Paolo (INFN, Pisa) ; Bagnaschi, Emanuele (CERN ; INFN, Italy) et al.
In order to stimulate new engagement and trigger some concrete studies in areas where further work would be beneficial towards fully understanding the physics potential of an $e^+e^-$ Higgs / Top / Electroweak factory, we propose to define a set of focus topics. [...]

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.

Interpreting LHCb's $\Lambda_b\to \Lambda_c\tau\bar\nu$ measurement and puzzles in semileptonic $\Lambda_b$ decays
/ Bernlochner, Florian U. (Bonn U.) ; Ligeti, Zoltan (LBL, Berkeley ; UC, Berkeley) ; Papucci, Michele (Caltech) ; Robinson, Dean J. (LBL, Berkeley ; UC, Berkeley)
Normalizing the recent LHCb measurement of $\Lambda_b \to \Lambda_c \tau \bar\nu$ to the standard model (SM) prediction for the $\Lambda_b \to \Lambda_c \mu \bar\nu$ rate, instead of a LEP measurement, provides a more consistent comparison with the SM prediction for the lepton flavor universality ratio $R(\Lambda_c)$. This modestly increases $R(\Lambda_c)$ compared to the quoted LHCb result, such that it no longer hints at a suppression compared to the SM, which would be hard to accommodate in new physics scenarios that enhance $R(D^{(*)})$. [...]

Origins of the method to determine the CKM angle $\gamma$ using $B^{\pm} \to D K^{\pm}$, $D \to K_{\rm S}^0\pi^+\pi^-$ decays
/ Ceccucci, A. (CERN) ; Gershon, T. (Warwick U.) ; Kenzie, M. (Warwick U.) ; Ligeti, Z. (LBL, Berkeley) ; Sakai, Y. (KEK, Tsukuba) ; Trabelsi, K. (IJCLab, Orsay)
The angle $\gamma$ of the Cabibbo--Kobayashi--Maskawa unitarity triangle is a benchmark parameter of the Standard Model of particle physics. [...]

Challenges in Semileptonic B Decays
/ Gambino, P. (Turin U. ; INFN, Turin) ; Kronfeld, A.S. (Fermilab) ; Rotondo, M. (Frascati) ; Schwanda, C. (Vienna, OAW) ; Bernlochner, F. (Bonn U.) ; Bharucha, A. (Marseille, CPT) ; Bozzi, C. (INFN, Ferrara) ; Calvi, M. (Milan Bicocca U. ; INFN, Milan Bicocca) ; Cao, L. (Bonn U.) ; Ciezarek, G. (CERN) et al.
Two of the elements of the Cabibbo-Kobayashi-Maskawa quark mixing matrix, $|V_{ub}|$ and $|V_{cb}|$, are extracted from semileptonic B decays. The results of the B factories, analysed in the light of the most recent theoretical calculations, remain puzzling, because for both $|V_{ub}|$ and $|V_{cb}|$ the exclusive and inclusive determinations are in clear tension.

Report from Working Group 4 : Opportunities in Flavour Physics at the HL-LHC and HE-LHC
/ Cerri, A. (Sussex U.) ; Gligorov, V.V. (Paris U., VI-VII) ; Malvezzi, S. (INFN, Milan Bicocca) ; Martin Camalich, J. (Laguna U., Tenerife ; IAC, La Laguna) ; Zupan, J. (Cincinnati U.) ; Akar, S. (Cincinnati U.) ; Alimena, J. (Ohio State U.) ; Allanach, B.C. (Cambridge U., DAMTP) ; Altmannshofer, W. (UC, Santa Cruz, Inst. Part. Phys.) ; Anderlini, L. (INFN, Florence) et al.
Motivated by the success of the flavour physics programme carried out over the last decade at the Large Hadron Collider (LHC), we characterize in detail the physics potential of its High-Luminosity and High-Energy upgrades in this domain of physics. We document the extraordinary breadth of the HL/HE-LHC programme enabled by a putative Upgrade II of the dedicated flavour physics experiment LHCb and the evolution of the established flavour physics role of the ATLAS and CMS general purpose experiments.
