The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 3,062 new measurements 721 papers, we list, evaluate, average measured properties gauge bosons the recently discovered Higgs boson, leptons, quarks, mesons, baryons. We summarize searches for hypothetical particles such as supersymmetric particles, heavy bosons, axions, dark photons, etc. All search limits are listed in Summary Tables. also give numerous tables, figures, formulae, reviews...

The LHC has observed, so far, 3 deviations from the Standard Model (SM) predictions in flavor observables: LHCb reported anomalies B→K*μ(+)μ(-) and R(K)=B→Kμ(+)μ(-)/B→Ke(+)e(-), while CMS found an excess h→μτ. We show, for first time, how these SM can be explained within a single well-motivated model: two-Higgs-doublet model with gauged L(μ)-L(τ) symmetry. find that, despite constraints τ→μμμ B(s)-B¯(s) mixing, one explain h→μτ, R(K) simultaneously, obtaining interesting correlations among...
We study the impact of an additional $U(1{)}^{\ensuremath{'}}$ gauge symmetry with flavor-dependent charges for quarks and leptons on LHC flavor anomalies observed in $B\ensuremath{\rightarrow}{K}^{*}{\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}$, $R(K)=B\ensuremath{\rightarrow}K{\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}/B\ensuremath{\rightarrow}K{e}^{+}{e}^{\ensuremath{-}}$, $h\ensuremath{\rightarrow}\ensuremath{\mu}\ensuremath{\tau}$. In its minimal version two...
The long-standing anomaly in the anomalous magnetic moment of muon indicates presence chirality violating new physics contributions. A possible solution involves scalar leptoquarks with left- and right-handed couplings to top quark. Two such representations exist for which contribution $(g\ensuremath{-}2{)}_{\ensuremath{\mu}}$ can possess an ${m}_{t}/{m}_{\ensuremath{\mu}}$ enhancement compared Standard Model. also induce loop corrections $Z$ muons probe as well contributions sources $SU(2)$...
Recent anomalies in the decays of $B$ mesons and Higgs boson provide hints towards lepton flavor (universality) violating physics beyond Standard Model. We observe that four-fermion operators which can explain $B$-physics have corresponding analogs kaon sector, we analyze their impact on $K\ensuremath{\rightarrow}\ensuremath{\pi}\ensuremath{\ell}{\ensuremath{\ell}}^{\ensuremath{'}}$ $K\ensuremath{\rightarrow}\ensuremath{\ell}{\ensuremath{\ell}}^{\ensuremath{'}}$...
Abstract Kaon physics is at a turning point – while the rare-kaon experiments NA62 and KOTO are in full swing, end of their lifetime approaching future experimental landscape needs to be defined. With HIKE, KOTO-II LHCb-Phase-II on table under scrutiny, it very good moment time take stock contemplate about opportunities these theoretical developments provide for particle coming decade beyond. This paper provides compact summary talks discussions from Kaons@CERN 2023 workshop, held September CERN.
Rare kaon decays offer a powerful tool for investigating new physics in $s\to d$ transitions. Currently, many of the interesting decay modes are either measured with rather large uncertainties compared to their theoretical predictions or have not yet been observed. The future HIKE programme at CERN will provide unprecedented sensitivity rare decays, allowing strong constraints on scenarios lepton flavour universality violation. We present overall picture that emerges from study different...
A rare decay K_{L}→μ^{+}μ^{-} has been measured precisely, while a K_{S}→μ^{+}μ^{-} will be observed by an upgrade of the LHCb experiment. Although both processes are almost CP-conserving decays, we point out that interference contribution between K_{L} and K_{S} in kaon beam emerges from genuine direct CP violation. It is found can change standard-model predictions at O(60%). We also stress unknown sign A(K_{L}→γγ) determined measurement interference, which much reduce theoretical...
We study ``soft leptogenesis'', a new mechanism of leptogenesis which does not require flavour mixing among the right-handed neutrinos. Supersymmetry soft-breaking terms give small mass splitting between CP-even and CP-odd sneutrino states single generation provide CP-violating phase sufficient to generate lepton asymmetry. The is successful if lepton-violating soft bilinear coupling unconventionally (but unnaturally) small. values neutrino masses predicted by can be low enough evade...
