Belle II status and early physicsPublic
The Belle II experiment at the SuperKEKB collider is a major upgrade of the KEK “B factory” facility in Tsukuba, Japan, aiming at an increase of the peak luminosity by a factor of 40. Commissioning of the SuperKEKB main ring took place in the first half of 2016. Phase 2 of the commissioning will start in April 2018 after the installation of the fina… |

Exotics at Belle and perspectives at Belle IIPublic
The search for multi-quark states beyond the constituent quark model (CQM) has resulted in the discovery of many new exotic states, starting with the observation of the X(3872), discovered by Belle in 2003. Also in the sector of charm-strange physics the CQM does not seem to describe properly all spectrum, despite of theoretical expectations. Thes… |

Commissioning and operation status of Belle II and SuperKEKBPublic
The luminosity of SuperKEKB is higher than KEKB by factor 40 with various upgraded points. Most important item of upgrades is to apply nano-beam collision with smaller horizontal beam size and larger cross angle. Then, higher luminosity can be obtained even with smaller vertical beta function. The Belle II is also upgraded to countermeasure higher… |

Plot of π0 → γ γ invariant mass in 5 pb-1 of collision dataPublic
This figure shows the invariant mass distribution of $\pi^0 \to \gamma \gamma$ in 5 pb$^{-1}$ of collision data. Events are required to contain at least three good tracks to purity the sample with processes of the type $e^+e^- \to $ hadrons, while rejecting beam induced background, Bhabha scattering, and other low multiplicity background sources. … |

First Collisions at Belle IIPublic
The Belle II experiment at the asymmetric energy e+e− collider SuperKEKB is a next generation B-factory, taking advantage of an upgrade of the collider complex to deliver about 40× the luminosity that was available to Belle. Together with a state-of-the-art detector upgrade, a rich physics program will be accessible by Belle II. Highlights are bey… |

Determination of Vub and VcbPublic
Semileptonic decays of $B$ mesons involving low-mass charged leptons $e$ or $\mu$ are expected to be free of non-Standard Model contributions and therefore play a critical role in determinations of $\vert V_{cb} \vert$ and $\vert V_{ub} \vert$ ($\vert V_{qb} \vert$). Decays of the form $b \to c \ell \bar \nu_\ell$ and $b \to u \ell \bar \nu_\ell$ … |

Study of the collision point properties.Public
One of the main goals of the phase 2 operation is to demonstrate the nano-beam collision scheme. Tracks from the collision region, reconstructed using hits from CDC and SVD with preliminary alignment are used to determine the $Z_0$ distribution |

Experimental status of |Vub/Vcb| and the CKM phase gammaPublic
Precision measurements of CKM parameters are important for defining the Standard Model and for searching for inconsistencies from new-physics contributions. I will review the status of current measurements and discuss the precision expected in future runs of LHCb and Belle II. |
