Kavli Affiliate: Misao Sasaki | First 5 Authors: Shi Pi, Misao Sasaki, Volodymyr Takhistov, Jianing Wang, | Summary: Primordial Black Holes (PBHs) can form from gravitational collapse of large overdensities in the early Universe, giving rise to rich phenomena in astrophysics and cosmology. We develop a novel, general, and accurate method based on theory of […]
Kavli Affiliate: Austin Joyce | First 5 Authors: Daniel Glazer, Austin Joyce, Maria J. Rodriguez, Luca Santoni, Adam R. Solomon | Summary: We study the scalar tidal responses of spinning higher-dimensional black holes, and their effective field theory description. After constructing the effective field theory of a spinning point particle in general dimension, we apply […]
Kavli Affiliate: Toshiyuki Kobayashi | First 5 Authors: Toshiyuki Kobayashi, , , , | Summary: This article is a record of the lecture at the centennial conference for Harish-Chandra. The admissibility theorem of Harish-Chandra concerns the restrictions of irreducible representations to maximal compact subgroups. In this article, we begin with a brief explanation of two […]
Kavli Affiliate: Jia Liu | First 5 Authors: Jia Liu, Yue Wang, Zhiqi Lin, Min Chen, Yixue Hao | Summary: Large language model fine-tuning techniques typically depend on extensive labeled data, external guidance, and feedback, such as human alignment, scalar rewards, and demonstration. However, in practical application, the scarcity of specific knowledge poses unprecedented challenges […]
Kavli Affiliate: Jonathan L. Rosner | First 5 Authors: Xiaocong Ai, Wolfgang Altmannshofer, Peter Athron, Xiaozhi Bai, Lorenzo Calibbi | Summary: We discuss the landscape of flavor physics at the Circular Electron-Positron Collider (CEPC), based on the nominal luminosity outlined in its Technical Design Report. The CEPC is designed to operate in multiple modes to […]

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 $CP$ violation parameters […]

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 […]
