We study the production and the decay of a heavy charged Higgs boson at the Large Hadron Collider (LHC) in gb fusion. The chiral structure of the $H^+ \bar{t} b$ coupling can trigger a particular spin state of the top quark produced in the decay of a Charged Higgs boson and therefore, is sensitive to the underlying mechanism of the electroweak symmetry breaking (EWSB). Taking two benchmark...

We propose a new mechanism for generating matter-antimatter asymmetry via the interference of tree-level diagrams only. We first derive a general result that a nonzero CP-asymmetry can be generated via at least two sets of interfering tree-level diagrams involving either 2→2 or 1→N(with N≥3) processes. We illustrate this point in a simple TeV-scale extension of the Standard Model with an inert...

We consider the cosmological relaxation solution to the electroweak hierarchy problem using the fermion production as a dominant friction force. In our approach, neither super-Planckian field excursions nor a large number of e-folds arise, and scanning over thermal Higgs mass squared is avoided. The produced fermions from the relaxion source through the derivative coupling are SM-singlets,...

We present the most systematic approach to discover a sterile neutrino $N$ or constrain $\left| U_{\ell N} \right|^2$, the mixing between active neutrino $\nu_\ell$ (with $\ell=\mu,\tau$) and the sterile neutrino $N$, from $B \to D\ell N$ decays. Our constraint on $\left| U_{\mu N} \right|^2$ achievable from Belle II data is comparable with that from the much larger data set of upgraded LHCb,...

The IBS-CAPP has currently accomplished all its technical challenges towards achieving the ultimate sensitivity in axion dark matter: DFSZ level even for 10% axion dark matter content in the local halo. Early next year we are expecting to receive a low temperature superconducting (LTS), 12T magnet LTS-12T/320mm, based on Nb3Sn cable, from Oxford Instruments, which will enable us to cover the...

We study the strong first order electroweak phase transition (SFOEWPT) with the SO(6)/SO(5) composite Higgs model, whose scalar sector contains one Higgs doublet and one real singlet. Six benchmark models are built with fermion embeddings in 1, 6, and 15 of SO(6). We show that SFOEWPT cannot be triggered under the minimal Higgs potential hypothesis, which assumes the scalar potential is...

In this talk, we present recent highlights of physics results from Belle, other than R(D()), R_K(). We also show a recent status of the Belle II experiment.

We propose a novel strategy to search for new physics signals in timing spectra, envisioning the situation in which new particles come from the decay of a heavier mother particle with a finite particle width. For example, the timing distribution of events induced by the dark matter particle scattering at the detector may populate in a relatively narrow range, forming a "resonance-like" shape....
