        Highlights of recent Belle physics results
        In this talk, we present recent highlights of the physics results from the Belle experiment. This includes the new measurements on B --> D(*) τ ν decays which can have significant implications for physics beyond the Standard Model such as 2HDM(II). In addition, we will discuss new results on dark sector search from Belle and other related results.

        Tau neutrino physics in SHiP
        A new fixed target experiment at CERN, SHiP is planned to search for the hidden particles using charmed mesons produced with 400 GeV proton beam. This experiment is also ideal for the study of tau neutrinos. I will present the cross section and the fluxes of the tau neutrinos and antineutrinos from the decay of the charmed meson, D_s. Also, I will discuss the estimation of the detectable events in this experiment.

        Weak nonleptonic decays of Ωc^0 baryon to axial-vector meson
        The axial-vector-emitting weak hadronic decays of the Ωc^0 baryon are investigated. After employing the factorization and the pole model framework to predict their branching ratios, we derive the symmetry- breaking effects on axial-vector-meson-baryon couplings and effects of flavor dependence on baryon- baryon weak transition amplitudes and, consequently, on their branching ratios.

        The 3-3-1 Models and Implication to Astroparticle Physics
        We study two versions of 3-3-1 model. The minimal 3-3-1 model behaved as the simple 3-3-1 model with the replication of \eta or of \chi can provide realistic dark matter candidates. The relic density is figured out as a function of the dark matter mass by using micrOMEGAs package. In addition, the 3-3-1 model with neutral fermions can be extended into 3-3-1-1 model by considering the lepton number as a local symmetry. We show that the 3-3-1-1 model can generate inflation as well as explain the baryon asymmetry of the Universe successfully.

        Nonleptonic B Meson Decay in the Perturbative QCD approach
        Using perturbative QCD approach, charmless $B_{u,d,s}\to VT$ decays are predicted. Their branching ratios, polarization fractions and direct CP violations are calculated. Within this approach the polarization fractions and the branching ratios of $B\to \phi(K_2^{*-}, \bar K_2^{*0})$ agree with the observed experimental data. However, the branching ratios of $B\to \omega(K_2^{*-}, \bar K_2^{*0})$ cannot be explained, where the polarization fractions can be accommodated. The tree dominated channels with a vector meson emitted have longitudinal polarization fraction of $90\%$, while the penguin dominating ones have subtle polarization fractions. Fortunately, most branching ratios of $B_{u,d}$ decays are of the order $10^{-6}$, which would be straight forward for experimental observations. For the $B_s$ decays, the branching ratios can reach the order of $10^{-6}$ in a vector emitted tree dominated decays. However, in penguin dominated decays those are of order of $10^{-7}$ which need more experimental data to be observed.

        Triplet Dark Matter from leptogenesis
        A triplet dark matter candidate from the thermal leptogenesis is considered with building a model. The model is based on the standard two Higgs doublet model and seesaw mechanism with Higgs triplets. The parameters (couplings and masses) are adjusted for the observed small neutrino mass and the leptogenesis. Dark matter particles can annihilate and decay in this model. The time evolution of dark matter number is governed by (co)annihilations in the expanding universe, and its mass is constrained by the observed relic density. The dark matter can decay into …nal states with three leptons (two charged leptons and one neutrino). We investigate whether the decay in galaxy can account for cosmic ray anomalies in the positron and electron spectrum. A noticeable point is that if the dark matter decays into each lepton with di¤erent branching ratios, cosmic ray anomalies in AMS-02 measurements of the positron fraction and the Fermi LAT measurements of the electrons-plus-positrons ‡ux could be simultaneously accounted for from its decay products.
