Oznake: physics of elementary particles;experimental physics;cross sections;particle production;B mesons;quarkonium;
We report the first measurement of the inclusive $\sigma(e^+e^-\to b\bar{b}\to D_s^+X)$ and $\sigma(e^+e^-\to b\bar{b}\to D^0/\bar{D}^0X)$ cross sections in the energy range from 10.63 to 11.02 GeV. Based on these results we determine $\sigma(e^+e^-\to B_s^0\bar{B}_s^0 X)$ and $\sigma(e^+e^-\to B\ba ...

We present a search for the rare flavor-changing neutral-current decay $B^0 \to K^{\ast 0}\tau^+\tau^-$ with data collected by the Belle II experiment at the SuperKEKB electron-positron collider. The analysis uses a 365  fb$^{−1}$ data sample recorded at the center-of-mass energy of the $\Upsilon(4⁢ ...

We present the first search for the lepton-flavor-violating decay modes $B^0 \to K^0_S\tau^{\pm}\ell^{\mp}(\ell = \mu, e)$ using the 711 and 365 fb$^{-1}$ data samples recorded by the Belle and Belle II detectors, respectively. We use a hadronic $B$-tagging technique to fully reconstruct a $B$ meson ...
