In this talk, we present recent results of semileptonic decays of B mesons from the Belle experiment. We will cover both the CKM-related results (i.e. Vub, Vcb) and the semi-tauonic decays, B -> D(*) tau nu.
I will discuss the present status of the Belle II experiment and future prospects. The presentation includes the early physics results we have produced and discussion on future sensitivity of new physics beyond standard model.
We study a holographic dual of near conformal dynamics. Using gauge-gravity duality, we calculate the mass of light dilaton and derive of the scale anomaly. Finally we show that the PCDC hypothesis holds in the holographic dual.
Neutrons can have nonvanishing electric dipole moment (EDM) when the theory has broken P and T symmetries. Since the CP violation (CPV) arising from the standard model (SM) is small or strongly suppressed at high temperature, new CPV from beyond the SM (BSM) is needed to explain the baryogenesis, and EDMs of elementary particles, such as the neutron, are good probes of such BSM physics. In...
Scale invariant extension of the SM with QCD-like strongly interacting hidden (dark) sector is interesting, since the dimensional transmutation and chiral symmetry breaking in the hidden sector could be the origin of electroweak symmetry breaking (EWSB), and all the masses of the SM particles as well as dark pions and dark baryons that could be good cold dark matter candidates. In this talk I...
The straightforward Monte Carlo simulation to Investigate the QCD phase diagram in finite termperature and baryon chemical potential is prohibited by the sign problem due to the complex fermion determinant. Indirect method can explore the low density region $\mu_B \le 3T$, where the sign problem is not severe. Rewriting the action can make the sign problem mild. Hence, we introduce the...
I will talk about a portal that connects the dark sector particles (axion and dark photon) to the bright sector particle (photon).
