The TOP counter of Belle II: status and first results

Umberto Tamponi

High-efficiency and high-purity particle identification are fundamental requirements for the success of the Belle II experiment, whose main goal is to explore the new-physics scena…

Observation of $Ξ (1620)^{0}$ and evidence for $Ξ (1690)^{0}$ in $Ξ_{c}^{+} \to Ξ^{-} π^{+} π^{+}$ decays

Belle collaboration, M. Sumihama, I. Adachi +183

We report the first observation of the doubly-strange baryon $Ξ (1620)^{0}$ in its decay to $Ξ^{-} π^{+}$ via $Ξ_{c}^{+} \to Ξ^{-} π^{+} π^{+}$ decays based on a $980 fb^{- 1}$ data sa…

Measurement of time-dependent $C P$ violation in $B^{0} \to K_{S}^{0} π^{0} π^{0}$ decays

Belle Collaboration, Y. Yusa, H. Aihara +155

We report a measurement of time-dependent $C P$ violation in $B^{0} \to K_{S}^{0} π^{0} π^{0}$ decays using a data sample of $772 \times 1 0^{6}$ $B B ˉ$ pairs collected by the Belle experime…

Measurement of the CKM Matrix Element $∣ V_{c b} ∣$ from $B^{0} \to D^{*-} ℓ^{+} ν_{ℓ}$ at Belle

E. Waheed, P. Urquijo, I. Adachi +184

We present a new measurement of the CKM matrix element $∣ V_{c b} ∣$ from $B^{0} \to D^{*-} ℓ^{+} ν_{ℓ}$ decays, reconstructed with the full Belle data set of $711 f b^{- 1}$ i…

Observation of Transverse $Λ/ Λ ˉ$ Hyperon Polarization in $e^{+} e^{-}$ Annihilation at Belle

Belle Collaboration, Y. Guan, A. Vossen +205

We report the first observation of the spontaneous polarization of $Λ$ and $Λ ˉ$ hyperons transverse to the production plane in $e^{+} e^{-}$ annihilation, which is attributed to the…

The Belle II Physics Book

E. Kou, P. Urquijo, W. Altmannshofer +524

We present the physics program of the Belle II experiment, located on the intensity frontier SuperKEKB $e^{+} e^{-}$ collider. Belle II collected its first collisions in 2018, and is ex…
