Measurement of the branching fraction of the decay $B^- to D^0 ρ(770)^-$ at Belle II

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, I. Adachi, L. Aggarwal, H. Aihara, N. Akopov | Summary: We measure the branching fraction of the decay $B^- to D^0 rho(770)^-$ using data collected with the Belle II detector. The data contain 387 million $Boverline{B}$ pairs produced in $e^+e^-$ collisions at the $Upsilon(4S)$ […]

Combined Pre-Supernova Alert System with Kamland and Super-Kamiokande

Kavli Affiliate: Kai Martens | First 5 Authors: KamLAND, Super-Kamiokande Collaborations, :, Seisho Abe, Minori Eizuka | Summary: Preceding a core-collapse supernova, various processes produce an increasing amount of neutrinos of all flavors characterized by mounting energies from the interior of massive stars. Among them, the electron antineutrinos are potentially detectable by terrestrial neutrino experiments […]

Enforcing Paraphrase Generation via Controllable Latent Diffusion

Kavli Affiliate: Jia Liu | First 5 Authors: Wei Zou, Ziyuan Zhuang, Shujian Huang, Jia Liu, Jiajun Chen | Summary: Paraphrase generation aims to produce high-quality and diverse utterances of a given text. Though state-of-the-art generation via the diffusion model reconciles generation quality and diversity, textual diffusion suffers from a truncation issue that hinders efficiency […]

Search for rare $b to dell^+ell^-$ transitions at Belle

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle, Belle II Collaborations, :, I. Adachi, L. Aggarwal | Summary: We present the results of a search for the $b to dell^+ell^-$ flavor-changing neutral-current rare decays $B^{+, 0} to (eta, omega, pi^{+,0}, rho^{+, 0}) e^+e^-$ and $B^{+, 0} to (eta, omega, pi^{0}, rho^{+}) mu^+mu^-$ using a […]

Mediator Decay through mixing with Degenerate Spectrum

Kavli Affiliate: Shigeki Matsumoto | First 5 Authors: Ayuki Kamada, Takumi Kuwahara, Shigeki Matsumoto, Yu Watanabe, Yuki Watanabe | Summary: The decay of the mediator particle into standard model (SM) particles plays a significant role in exploring the dark sector scenario. We consider such a decay, taking the dark photon mediator as an example that […]
