Summary: In this paper, the authors propose a strategy to discern whether new physics in the Wilson coefficient C-9 mu violates lepton flavor universality dominantly or contains a sizable lepton flavor universal component. Distinguishing between these two cases is crucial for advancing our understanding of the B anomalies. The authors identify the origin of the degeneracy and suggest key observables that can break it. They also discuss the possible origins of the lepton flavor universal component and provide predictions for certain branching ratios.

Summary: In extended Higgs models, a discrete symmetry is required in the quark sector, but not necessarily in the lepton sector. We present a four-doublet model where one Higgs couples to quarks and three others couple to the electron, muon, and tau. The model is studied with various constraints and it is shown that the lighter additional scalars can decay into electrons and muons.

Summary: In this study, models are proposed to explain the hierarchical structures of masses and mixing in both quark and lepton sectors using the S ⠂4 modular flavor symmetry. The hierarchies are realized through the use of a small parameter c and powers of 2Imt, controlled by modular weights. The model successfully explains the hierarchies in both quark and lepton sectors with O(1) coefficients.

Summary: A novel method is proposed to probe lepton flavor universality violation in semileptonic B decays by comparing inclusive rates of different decay processes. The measurement is directly related to a specific ratio and can suppress the effects of mixing and other factors through appropriate experimental cuts.

Summary: We search for lepton-flavor-violating tau- -> e-alpha and tau- -> mu-alpha decays using SuperKEKB collider's electron-positron collisions at 10.58 GeV center-of-mass energy. With an integrated luminosity of 62.8 fb-1 collected by the Belle II detector, we look for an excess in the lepton-energy spectrum of tau- -> e- nu over bar e nu tau and tau- -> mu- nu over bar mu nu tau decays. Our results provide the most stringent bounds on invisible boson production from tau decays, with 95% confidence-level upper limits on the branching-fraction ratio for alpha masses between 0 and 1.6 GeV/c^2.

Summary: A semi-inclusive lepton flavor universality (LFU) ratio, R-Sigma, is constructed to test mu/e universality in b -> sl(+)l(-) transitions at e(+)e(-) B-meson factories. By combining different decay channels, this observable maximizes sensitivity to possible violations of LFU from short-distance origin, while maintaining a clean theoretical interpretation in case of deviation from its Standard Model prediction, R-Sigma(SM) = 1.

Summary: Researchers studied the leptophilic weakly interacting massive particle (WIMP) in a minimal renormalizable model scenario where scalar mediators establish interactions between WIMPs and standard model leptons. They conducted a comprehensive analysis for two distinct cases with different mediators, discussed the potential role of future lepton collider experiments, and explored a combined model capable of explaining the muon g-2 anomaly. The study suggests that the region allowed by the latest muon (g-2) result can be probed at future colliders, providing simultaneous authentication of the model scenario.

Summary: In this study, the rare decays of neutral vector mesons J/? and r(nS) are analyzed in the minimal R-symmetric supersymmetric standard model using the effective Lagrangian method. The predicted branching ratios are mainly determined by the mass insertion parameters d(ij), which are off-diagonal inputs, with comparable contributions from different parts. Considering the experimental constraints on the mass insertion parameters, the predicted branching ratios for the most promising process r(nS) ? lt are ten orders of magnitude smaller than the present experimental bounds.

Summary: Motivated by flavor symmetry models, we propose theories with lepton flavor triality in the low-energy limit, which predict the presence of flavor-violating decays tau +/- -> mu +/- mu +/- e and tau +/- -> e +/- e +/- mu as the main phenomenological signatures beyond the standard model. These decays are expected to be investigated with improved sensitivity by the Belle II experiment at the SuperKEKB collider. We analyze the phenomenology of these theories, which involve doubly charged scalars mediating the above-mentioned decay processes.

Summary: In this study, we investigated lepton flavor violating decays of Z gauge boson and Higgs boson in the scotogenic model. We calculated the branching ratios for these decays and found that they can be significant after considering neutrino oscillation observables. However, the branching ratio results are suppressed after satisfying constraints from other experimental observations.

Summary: Flavor violating processes in the lepton sector have highly suppressed branching ratios in the standard model, making observation of lepton flavor violation a clear indication of physics beyond the standard model. In this review, we discuss new physics searches in processes that violate the conservation of lepton (muon) flavor by two units with muonia and muonium-antimuonium oscillations.

Summary: We investigate collider signatures of standard model extensions involving vector-like leptons and a flavorful scalar sector. By focusing on Yukawa couplings and masses that can explain current data on muon and electron anomalous magnetic moments, we find that flavorful vector-like leptons may be excluded within certain mass ranges. We also design novel observables based on opposite sign opposite flavor invariant masses to signal new physics and extract mass hierarchies in upcoming searches at the LHC and the HL-LHC.

Summary: This study systematically investigates new physics scenarios that can modify the interactions between neutrinos and matter, with a focus on the importance of tau neutrino telescopes in probing physics associated with the second and third generations. By analyzing experimental configurations and numerically solving propagation equations, the study obtains the sensitivities of upcoming tau neutrino telescopes to charged Higgs and leptoquark models. The combination of different telescopes is complementary in exploring new physics.

Summary: The measurements from the coherent elastic neutrino-nucleus scattering (CE nu NS) experiments have opened up possibilities to study neutrino physics beyond the standard model. This paper presents constraints on non-standard interactions (NSIs) and mediators derived from CONUS germanium data. The study found that the CONUS experiment has set the world's best limits on tensor NSIs and has the potential to probe coupling constants for scalar and vector mediators.

Summary: A novel online distillation technique was developed to reduce intrinsic background components, such as krypton, in the XENON1T dark matter experiment. The technique continuously purifies the gaseous volume of the detector system and achieved the lowest krypton concentration measured in an operating dark matter detector. A model was developed to describe the krypton evolution in the system over a span of 550 days.

Summary: Anomalies in past neutrino measurements have led to the discovery of non-zero neutrino mass and oscillation between different flavors. The STEREO experiment aimed to investigate the existence of a supplementary, sterile neutrino state that does not interact via weak interaction. The analysis of data from the STEREO experiment confirms observed anomalies while rejecting the hypothesis of a light sterile neutrino.

Summary: The selection of low-radioactive construction materials is crucial for the XENONnT experiment. Extensive radioassay program results show a reduction in materials background by about 17% compared to the predecessor, XENON1T. The expected Rn-222 activity concentration in XENONnT is determined to be three times lower than XENON1T, and it will be further reduced by a novel radon distillation system.

Summary: In the Standard Model, the masses and mixing angles of fermions, except for neutrinos, can be described by Yukawa couplings. However, the hierarchies and regularities in quark and lepton masses remain a mystery. This article proposes a new class of models with vectorlike fermions that may address this problem and provide a new mechanism for fermion mass generation.
