We investigate the scalar potential with soft breaking terms and flavor part of a general $S_3$-symmetric three-Higgs-doublet model. By assuming that the quarks, leptons and Higgs fields belong to irreducible representation of the permutation group $S_3$ and CP violation, parameter space that can reproduce quark masses, lepton masses, CKM matrix, PMNS matrix is obtained, which also satisfies...

B decays form an ideal playground for indirect effects of new physics beyond the Standard Model (SM). At present there are several examples where experimental results deviate from the SM predictions. If these anomalies persist, new avenues will be necessary to pinpoint the nature of new physics. I will discuss a couple of B-decay channels, hadronic and semileptonic, where progress has been...

I will discuss the resonant production and detection of charged mesons in existing and near-future neutrino scattering experiments with $E_\nu \lesssim 1$ TeV, characteristic of high-energy atmospheric neutrinos or collider-sourced neutrino beams.

The most promising candidate is the reaction $\bar{\nu}_e e^-\rightarrow \rho^-\rightarrow \pi^- \pi^0$. I will discuss detection prospects at... -

The Belle II experiment at the SuperKEKB energy-asymmetric $e^+ e^-$ collider is a substantial upgrade of the B factory facility at the Japanese KEK laboratory. The design luminosity of the machine is $6\times 10^{35}$ cm$^{-2}$s$^{-1}$ and the Belle II experiment aims to ultimately record 50 ab$^{-1}$ of data, a factor of 50 more than its predecessor. With this data set, Belle II will be able...

The QCD axion is a well-motivated addition to the standard model to solve the strong $CP$ problem. If the axion acquires mass dominantly from a hidden sector, it can be as heavy as $O(1)$ GeV, and the decay constant can be as low as $O(100)$ GeV without running into the axion quality problem. We propose new search strategies for such heavy QCD axions at the Belle II experiment, where the...

Experimental hints for lepton-flavor universality violation in the muon's magnetic moment as well as neutral- and charged-current $B$-meson decays require Standard-Model extensions by particles such as leptoquarks that generically lead to unacceptably fast rates of charged lepton flavor violation and proton decay. We propose a model based on a gauged $U(1)_{L_\mu-L_\tau}$ that eliminates all...
