Observation of time-dependent $CP$ violation and measurement of the branching fraction of $B^0 to J/ψπ^0$ decays

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, I. Adachi, L. Aggarwal, H. Ahmed, H. Aihara | Summary: We present a measurement of the branching fraction and time-dependent charge-parity ($CP$) decay-rate asymmetries in $B^0 to J/psi pi^0$ decays. The data sample was collected with the Belle~II detector at the SuperKEKB asymmetric $e^+e^-$ […]

Systematic collapse of the accretion disc in AGN confirmed by UV photometry and broad line spectra

Kavli Affiliate: John D. Silverman | First 5 Authors: Jia-Lai Kang, Chris Done, Scott Hagen, Matthew J. Temple, John D. Silverman | Summary: A recent study on the spectral energy distribution (SED) of AGN combined unobscured X-ray sources from the eROSITA eFEDS Survey with high quality optical imaging from Subaru’s Hyper Suprime-Cam (HSC). The HSC […]

Tomographic constraint on anisotropic cosmic birefringence

Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Toshiya Namikawa, , , , | Summary: We for the first time constrain anisotropic cosmic birefringence generated at reionization using Planck PR4 polarization data. Several recent analyses of WMAP and Planck polarization data have found a tantalizing hint of isotropic cosmic birefringence. Ongoing and future CMB experiments […]

Cosmological constraints using Minkowski functionals from the first year data of the Hyper Suprime-Cam

Kavli Affiliate: Jia Liu | First 5 Authors: Joaquin Armijo, Gabriela A. Marques, Camila P. Novaes, Leander Thiele, Jessica A. Cowell | Summary: We use Minkowski functionals to analyse weak lensing convergence maps from the first-year data release of the Subaru Hyper Suprime-Cam (HSC-Y1) survey. Minkowski functionals provide a description of the morphological properties of […]

Crimson Behemoth: a Massive Clumpy Structure Hosting a Dusty AGN at $z=4.91$

Kavli Affiliate: John D. Silverman | First 5 Authors: Takumi S. Tanaka, John D. Silverman, Yurina Nakazato, Masafusa Onoue, Kazuhiro Shimasaku | Summary: The current paradigm for the co-evolution of galaxies and their supermassive black holes postulates that dust-obscured active galactic nuclei (AGNs) represent a transitional phase towards a more luminous and unobscured state. However, […]

Long-lived Sterile Neutrino Searches at Future Muon Colliders

Kavli Affiliate: Jia Liu | First 5 Authors: Qi Bi, Jinhui Guo, Jia Liu, Yan Luo, Xiao-Ping Wang | Summary: We explore the potential of studying sterile neutrinos at a future high-energy muon collider, where these particles can generate small active neutrino masses via the seesaw mechanism and exhibit long-lived particle signatures. A Dirac sterile […]

Ctrl-GenAug: Controllable Generative Augmentation for Medical Sequence Classification

Kavli Affiliate: Jia Liu | First 5 Authors: Xinrui Zhou, Yuhao Huang, Haoran Dou, Shijing Chen, Ao Chang | Summary: In the medical field, the limited availability of large-scale datasets and labor-intensive annotation processes hinder the performance of deep models. Diffusion-based generative augmentation approaches present a promising solution to this issue, having been proven effective […]

Search for $C!P$ violation in $D^+_{(s)}to{}K_{S}^{0}K^{-}π^{+}π^{+}$ decays using triple and quadruple products

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle, Belle II Collaborations, :, L. Aggarwal, H. Ahmed | Summary: We perform the first search for $C!P$ violation in ${D_{(s)}^{+}to{}K_{S}^{0}K^{-}pi^{+}pi^{+}}$ decays. We use a combined data set from the Belle and Belle II experiments, which study $e^+e^-$ collisions at center-of-mass energies at or near the $Upsilon(4S)$ […]

Gravitational waves from primordial black hole isocurvature: the effect of non-Gaussianities

Kavli Affiliate: Misao Sasaki | First 5 Authors: Xin-Chen He, Yi-Fu Cai, Xiao-Han Ma, Theodoros Papanikolaou, Emmanuel N. Saridakis | Summary: Ultra-light primordial black holes (PBHs) with masses $M_{rm PBH}<5times 10^8mathrm{g}$ can dominate transiently the energy budget of the Universe and reheat the Universe through their evaporation taking place before Big Bang Nucleosynthesis. The isocurvature […]

Topological K-theory of quasi-BPS categories for Higgs bundles

Kavli Affiliate: Yukinobu Toda | First 5 Authors: Tudor Pădurariu, Yukinobu Toda, , , | Summary: In a previous paper, we introduced quasi-BPS categories for moduli stacks of semistable Higgs bundles. Under a certain condition on the rank, Euler characteristic, and weight, the quasi-BPS categories (called BPS in this case) are non-commutative analogues of Hitchin […]
