Direct Comparison of Magnetic Penetration Depth in Kagome Superconductors AV$_3$Sb$_5$ (A = Cs, K, Rb)

Posted by dbos Cornell, This Week: Nanoscience

Kavli Affiliate: Katja C. Nowack | First 5 Authors: Austin Kaczmarek, Andrea Capa Salinas, Stephen D. Wilson, Katja C. Nowack, | Summary: We report measurements of the local temperature-dependent penetration depth, $lambda(T)$, in the Kagome superconductors AV$_3$Sb$_5$ (A = Cs, K, Rb) using scanning superconducting quantum interference device (SQUID) microscopy. Our results suggest that the […]

Flavor Physics at CEPC: a General Perspective

Posted by dbos This Week: Astrophysics, Tokyo

Kavli Affiliate: Jia Liu | 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 address […]

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 This Week: Astrophysics, 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 $CP$ violation parameters […]

Comprehensive Bayesian Exploration of Froggatt-Nielsen Mechanism

Posted by dbos This Week: Astrophysics, 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 […]
