Measurements of the absolute branching fractions of $B^{+} \to X_{c\bar{c}} K^{+}$ and $B^{+} \to \bar{D}^{(\ast) 0} \pi^{+} $ at Belle
[arXiv:1709.06108]
 GO
We present the measurement of the absolute branching fractions of $B^{+} \to X_{c\bar{c}} K^{+}$ and $B^{+} \to \bar{D}^{(\ast) 0} \pi^{+} $ decays, using a data sample of $772\times10^{6}$ $B\bar{B}$ pairs collected at the $\Upsilon(4S)$ resonance with the Belle detector at the KEKB asymmetric-energy $e^{+}e^{-}$ collider. Here, $X_{c\bar{c}}$ denotes $\eta_{c}$, $J/\psi$, $\chi_{c0}$, $\chi_{c1}$, $\eta_{c}(2S)$, $\psi(2S)$, $\psi(3770)$, $X(3872)$, and $X(3915)$. [...]

Angular analysis of the $e^+ e^- \to D^{(*) \pm} D^{* \mp}$ process near the open charm threshold using initial-state radiation
[BELLE-PREPRINT-2017-15; KEK-PREPRINT-2017-16; arXiv:1707.09167]
 GO
We report a new measurement of the exclusive $e^+ e^- \to D^{(*) \pm} D^{*\mp}$ cross sections as a function of the center-of-mass energy from the $D^{(*) \pm} D^{* \mp}$ threshold through $\sqrt{s}=6.0$ GeV with initial-state radiation. The analysis is based on a data sample collected with the Belle detector with an integrated luminosity of $951$ fb$^{-1}$. [...]

Study of $\eta$ and dipion transitions in $\Upsilon(4S)$ decays to lower bottomonia
[BELLE-PREPRINT-2017-16; KEK-PREPRINT-2017-17; arXiv:1707.04973]
 GO
We study hadronic transitions between bottomonium states using 496 fb$^{-1}$ data collected at the $\Upsilon(4S)$ resonance with the Belle detector at the KEKB asymmetric energy $e^{+}e^{-}$ collider. We measure: ${\cal B}(\Upsilon(4S)\to\pi^+\pi^-\Upsilon(1S))=(8.2\pm 0.5 {\rm(stat.)} \pm 0.4 {\rm(syst.)})\times10^{-5}$, ${\cal B}(\Upsilon(4S)\to\pi^+\pi^-\Upsilon(2S))=(7.9\pm 1.0 {\rm(stat.)} \pm 0.4 {\rm(syst.)})\times10^{-5}$, and ${\cal B}(\Upsilon(4S)\to\eta\Upsilon(1S))=(1.70\pm 0.23 {\rm(stat.)} \pm 0.08 {\rm(syst.)})\times10^{-4}$.

Evidence for Isospin Violation and Measurement of $CP$ Asymmetries in $B \to K^{\ast}(892) \gamma$
[BELLE-PREPRINT-2017-08; KEK-PREPRINT-2017-4; arXiv:1707.00394]
 GO
We report the first evidence for isospin violation in $B \to K^* \gamma$ and the first measurement of difference of $CP$ asymmetries between $B^+ \to K^{*+} \gamma$ and $B^0 \to K^{*0} \gamma$. This analysis is based on the data sample containing $772 \times 10^6 B\bar{B}$ pairs that was collected with the Belle detector at the KEKB energy-asymmetric $e^+ e^-$ collider. [...]

Search for $\Lambda_c^+\to\phi p \pi^0$ and measurement of $\Lambda_c^+\to K^-\pi^+ p \pi^0$ decays
[BELLE-PREPRINT-2017-12; KEK-PREPRINT-2017-08; UCHEP-2017-06; arXiv:1707.00089]
 GO
We have searched for the Cabibbo-suppressed decay $\Lambda_c^+\to\phi p\pi^0$ in $e^+e^-$ collisions using a data sample corresponding to an integrated luminosity of 915 $\rm fb^{-1}$. The data were collected by the Belle experiment at the KEKB $e^+e^-$ asymmetric-energy collider running at or near the $\Upsilon(4S)$ and $\Upsilon(5S)$ resonances. [...]

Production cross sections of hyperons and charmed baryons from $e^+e^-$ annihilation near $\sqrt{s} =$ 10.52 GeV
[BELLE-PREPRINT-2017-14; KEK-PREPRINT-2017-15; arXiv:1706.06791]
 GO
We measure the inclusive production cross sections of hyperons and charmed baryons from $e^+e^-$ annihilation using a 800 fb$^{-1}$ data sample taken near the $\Upsilon(4S)$ resonance with the Belle detector at the KEKB asymmetric-energy $e^+ e^-$ collider. The feed-down contributions from heavy particles are subtracted using our data, and the direct production cross sections are presented for the first time. [...]

Invariant-mass and fractional-energy dependence of inclusive production of di-hadrons in $e^+e^-$ annihilation at $\sqrt{s}=$ 10.58 GeV
[BELLE-DRAFT-2017-13-; KEK-DRAFT-2017-09; arXiv:1706.08348; BELLE-DRAFT-2017-13-KEK-DRAFT-2017-09] ddc:530
The inclusive cross sections for dihadrons of charged pions and kaons $(e^+ e^- \to hhX)$ in electron-positron annihilation are reported. They are obtained as a function of the total fractional energy and invariant mass for any di-hadron combination in the same hemisphere as defined by the thrust event-shape variable and its axis.

Palaiseau : LLR, 230-236 (2013) [10.3204/PUBDB-2017-10890]  GO
The Analog Hadron Calorimeter is an option for the hadronic calorimeter of a future linear collider detector, based on scintillator tiles read out by silicon photomultipliers. The high channel density compared to current collider detectors requires an integration of the readout electronics into the active detector layers. [...]

The two-loop electroweak bosonic corrections to $\sin^2\theta_{\textrm{eff}}^{\textrm{b}}$
[DESY-16-119; KW-16-002; arXiv:1607.08375] ddc:530
The prediction of the effective electroweak mixing angle $\sin^2\theta_{\rm eff}^{\rm b}$ in the Standard Model at two-loop accuracy has now been completed by the first calculation of the bosonic two-loop corrections to the $Z{\bar b}b$ vertex. Numerical predictions are presented in the form of a fitting formula as function of $M_Z, M_W, M_H, m_t$ and $\Delta{\alpha}$, ${\alpha_{\rm s}}$. [...]
