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 […]
Kavli Affiliate: Jia Liu | First 5 Authors: Wei Zou, Ziyuan Zhuang, Xiang Geng, Shujian Huang, Jia Liu | Summary: Paraphrase generation strives to generate high-quality and diverse expressions of a given text, a domain where diffusion models excel. Though SOTA diffusion generation reconciles generation quality and diversity, textual diffusion suffers from a truncation issue […]
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 […]

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 […]

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, I. Adachi, L. Aggarwal, H. Aihara, N. Akopov | Summary: We report a measurement of the $e^+e^- to pi^+pi^-pi^0$ cross section in the energy range from 0.62 to 3.50 GeV using an initial-state radiation technique. We use an $e^+e^-$ data sample corresponding to 191 […]
Kavli Affiliate: Misao Sasaki | First 5 Authors: Xinpeng Wang, Ying-li Zhang, Misao Sasaki, , | Summary: We investigate a model of $R^2$-gravity with a non-minimally coupled scalar field that gives rise to two-stage inflation with a break, that is, with an intermediate stage where inflation momentarily halts. We find that the power spectrum of […]
