Measurement of the inclusive branching fractions for $B_s^0$ decays into $D$ mesons via hadronic tagging

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle, Belle II Collaborations, :, I. Adachi, L. Aggarwal | Summary: We report measurements of the absolute branching fractions $mathcal{B}(B_s^0 to D_s^{pm} X)$, $mathcal{B}(B_s^0 to D^0/bar{D}^0 X)$, and $mathcal{B}(B_s^0 to D^{pm} X)$, where the latter is measured for the first time. The results are based on a […]

Preparation and observation of anomalous counterpropagating edge states in a periodically driven optical Raman lattice

Kavli Affiliate: Long Zhang | First 5 Authors: Hongting Hou, Long Zhang, , , | Summary: Motivated by the recent observation of real-space edge modes with ultracold atoms [Braun et al., Nat. Phys. 20, 1306 (2024)], we investigate the preparation and detection of anomalous counterpropagating edge states — a defining feature of the anomalous Floquet […]
