Abstract The Silicon Vertex Detector of Belle II is a state-of-the-art tracking and vertexing system based on double-sided silicon strip sensors, designed fabricated by large international collaboration in the period 2012–2018. Since 2019 it has been operation providing high quality data with small number defective channels (<1%), hit-finding efficiency (>99%), good signal-to-noise ratio (well excess 10 for all sensor configurations tracks). Together control over alignment, these are...
A bstract We measure the branching fractions and CP asymmetries for singly Cabibbo-suppressed decays D 0 → π + − η , K ϕη using 980 fb 1 of data from Belle experiment at KEKB e collider. obtain $$ {\displaystyle \begin{array}{c}\mathcal{B}\left({D}^0\to {\pi}^{+}{\pi}^{-}\eta \right)=\left[1.22\pm 0.02\left(\mathrm{stat}\right)\pm 0.02\left(\mathrm{syst}\right)\pm 0.03\left({\mathcal{B}}_{\mathrm{ref}}\right)\right]\times {10}^{-3},\\ {}\mathcal{B}\left({D}^0\to {K}^{+}{K}^{-}\eta...
Abstract Transient current sheets (CSs) are common magnetic structures in the solar wind that can significantly disturb planetary space environment and cause weather phenomena. This study focuses on their properties Martian investigates transformations caused by bow shock. Based 14 months of data from Mars Atmosphere Volatile Evolution mission during similar activity, 786 CSs with directional changes greater than 90° field depression were automatically identified, including 256 events...
The Belle II experiment at the SuperKEKB collider of KEK (Japan) will accumulate 50 ab$^{-1}$ $e^+e^-$ collision data an unprecedented instantaneous luminosity $8\times 10^{35}$ cm$^{-2}$s$^{-1}$, about 40 times larger than its predecessor. vertex detector (VXD) provides inner tracking, impact parameter measurement and decay reconstruction for consists two layers DEPFET-based pixels (PXD) four double sided silicon strip detectors (SVD), latter being focus this paper. We review design SVD...
