Measurement of the branching fraction, polarization, and time-dependent $CP$ asymmetry in $B^0 to ρ^+ρ^-$ decays and constraint on the CKM angle $φ_2$

Posted by dbos Tokyo

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, I. Adachi, L. Aggarwal, H. Ahmed, N. Akopov | Summary: We present a measurement of the branching fraction and fraction of longitudinal polarization of $B^0 to rho^+ rho^-$ decays, which have two $pi^0$’s in the final state. We also measure time-dependent {it CP} violation […]

Comprehensive Bayesian Exploration of Froggatt-Nielsen Mechanism

Posted by dbos Tokyo

Kavli Affiliate: Satoshi Shirai | First 5 Authors: Masahiro Ibe, Satoshi Shirai, Keiichi Watanabe, , | Summary: The Froggatt-Nielsen (FN) mechanism successfully explains the hierarchical structure of fermion Yukawa couplings by introducing a U(1) flavor symmetry with distinct charge assignments for different fermion generations. While some FN charge assignments have been proposed, their evaluation has […]

Gravitational Waves from Post-Collision of Fuzzy Dark Matter Solitons

Posted by dbos Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Chen Tan, Jing-Kang Bin, Ke Wang, , | Summary: According to the Schr"odinger-Poisson (SP) equations, fuzzy dark matter (FDM) can form a stable equilibrium configuration, the so-called FDM soliton. The SP system can also determine the evolution of FDM solitons, such as head-on collision. In this paper, […]

2D numerical simulation of lunar response to gravitational waves using finite element method

Posted by dbos Peking

Kavli Affiliate: Xian Chen | First 5 Authors: Lei Zhang, Han Yan, Xian Chen, Jinhai Zhang, | Summary: Previous studies of the response of the Moon to gravitational waves have been carried out using analytical or semi-analytical models assuming ideal lunar structures. Such models are advantageous for their high-speed calculation but fail to account for […]

Bulge Oscillation Driven by Outflows of Active Galactic Nuclei. I. Fast Outflow Case

Posted by dbos Peking

Kavli Affiliate: Luis C. Ho | First 5 Authors: Yue-Chang Peng, Jian-Min Wang, Yu Zhao, Luis C. Ho, | Summary: There is growing evidence for star formation inside outflows of active galactic nuclei (AGNs). The formed stars are injected into bulges and give rise to perturbation of bulges. In this paper, we investigate the issues […]
