Measurement of branching-fraction ratios and $CP$ asymmetries in $B^{pm} to D_{CPpm}K^{pm}$ decays at Belle and Belle II

Posted by klaurent Tokyo

Kavli Affiliate: T. Higuchi | First 5 Authors: The Belle, Belle II Collaborations, :, I. Adachi, L. Aggarwal | Summary: We report results from a study of $B^pm rightarrow DK^pm$ decays followed by $D$ decaying to $CP$~eigenstates, where $D$ indicates a $D^0$ or $bar{D}^{0}$ meson. These decays are sensitive to the Cabibbo-Kobayashi-Maskawa unitarity-triangle angle $phi_{3}$. […]

Quantum Gravity Effects on Dark Matter and Gravitational Waves

Posted by klaurent Tokyo

Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Stephen F. King, Rishav Roshan, Xin Wang, Graham White, Masahito Yamazaki | Summary: We explore how quantum gravity effects, manifested through the breaking of discrete symmetry responsible for both Dark Matter and Domain Walls, can have observational effects through CMB observations and gravitational waves. To illustrate the […]

Superradiant instabilities of massive bosons around exotic compact objects

Posted by klaurent Peking

Kavli Affiliate: Lijing Shao | First 5 Authors: Lihang Zhou, Richard Brito, Zhan-Feng Mai, Lijing Shao, | Summary: Superradiantly unstable ultralight particles around a classical rotating black hole (BH) can form an exponentially growing bosonic cloud, which have been shown to provide an astrophysical probe to detect ultralight particles and constrain their mass. However, the […]

The Cepheid Extragalactic Distance Scale: Past, Present and Future

Posted by klaurent Chicago

Kavli Affiliate: Wendy L. Freedman | First 5 Authors: Wendy L. Freedman, Barry F. Madore, , , | Summary: Cepheids have been the cornerstone of the extragalactic distance scale for a century. With high-quality data, these luminous supergiants exhibit a small dispersion in their Leavitt (period-luminosity) relation, particularly at longer wavelengths, and few methods rival […]

Fractional revival on semi-Cayley graphs over abelian groups

Posted by klaurent Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Ligong Wang, Xiaogang Liu, , | Summary: In this paper, we investigate the existence of fractional revival on semi-Cayley graphs over finite abelian groups. We give some necessary and sufficient conditions for semi-Cayley graphs over finite abelian groups admitting fractional revival. We also show that […]

ES-MVSNet: Efficient Framework for End-to-end Self-supervised Multi-View Stereo

Posted by klaurent Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Qiang Zhou, Chaohui Yu, Jingliang Li, Yuang Liu, Jing Wang | Summary: Compared to the multi-stage self-supervised multi-view stereo (MVS) method, the end-to-end (E2E) approach has received more attention due to its concise and efficient training pipeline. Recent E2E self-supervised MVS approaches have integrated third-party models (such […]

Tests of light-lepton universality in angular asymmetries of $B^0 to D^{*-} ell ν$ decays

Posted by klaurent Tokyo

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, I. Adachi, K. Adamczyk, L. Aggarwal, H. Aihara | Summary: We present the first comprehensive tests of light-lepton universality in the angular distributions of semileptonic Bz-meson decays to charged spin-1 charmed mesons. We measure five angular-asymmetry observables as functions of the decay recoil that […]
