Evidence of the P_ccbars(4459)0 in Upsilon(1S, 2S) inclusive decays at Belle

Kavli Affiliate: T. Higuchi | First 5 Authors: I. Adachi, L. Aggarwal, H. Ahmed, J. K. Ahn, H. Aihara | Summary: Using data samples of 102 million Upsilon(1S) events and 158 million Upsilon(2S) events collected by the Belle detector at the KEKB asymmetric-energy e+e- collider, we search for [udsccbar] pentaquark states decaying to Jpsi Lambda. […]

$Λ$CDM and early dark energy in latent space: a data-driven parametrization of the CMB temperature power spectrum

Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Davide Piras, Laura Herold, Luisa Lucie-Smith, Eiichiro Komatsu, | Summary: Finding the best parametrization for cosmological models in the absence of first-principle theories is an open question. We propose a data-driven parametrization of cosmological models given by the disentangled ‘latent’ representation of a variational autoencoder (VAE) trained […]

How does the restriction of representations change under translations? A story for the general linear groups and the unitary groups

Kavli Affiliate: Toshiyuki Kobayashi | First 5 Authors: Toshiyuki Kobayashi, Birgit Speh, , , | Summary: We present a new approach to symmetry breaking for pairs of real forms of $(GL(n, mathbb{C}), GL(n-1, mathbb{C}))$. While translation functors are a useful tool for studying a family of representations of a single reductive group $G$, when applied […]

Gamma-ray emission from decays of boosted nuclei in proto-magnetar jets

Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Sean Heston, Nick Ekanger, Shunsaku Horiuchi, , | Summary: We examine the detectability of $gamma$-ray emission originating from the radioactive decays of unstable nuclei that are synthesized in relativistic outflows launched in magneto-rotational core-collapse supernovae. The observed lines have enhanced energies due to the Lorentz boosted nuclei […]

Nonrenormalization Theorem for ${cal N}=(4,4)$ Interface Entropy

Kavli Affiliate: Hirosi Ooguri | First 5 Authors: Andreas Karch, Hirosi Ooguri, Mianqi Wang, , | Summary: We derive a formula for the half-BPS interface entropy between any pair of ${cal N}=(4,4)$ theories on the same conformal manifold. This generalizes the diastasis formula derived in arXiv:1311.2202 for ${cal N}=(2,2)$ theories, which is restricted to the […]

Measurement of $B^+toτ^+ν_τ$ branching fraction with a hadronic tagging method at Belle II

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, I. Adachi, K. Adamczyk, H. Ahmed, Y. Ahn | Summary: We present a measurement of the branching fraction of $B^+totau^+nu_tau$ decays using $(387pm6)times 10^6$ $Upsilon(4S)$ collected between 2019 and 2022 with the Belle II detector at the SuperKEKB $e^+e^-$ collider. We reconstruct the accompanying […]

Momentum and Matter Matter for Axion Dark Matter Matters on Earth

Kavli Affiliate: Yevgeny V. Stadnik | First 5 Authors: Abhishek Banerjee, Itay M. Bloch, Quentin Bonnefoy, Sebastian A. R. Ellis, Gilad Perez | Summary: We investigate the implications of matter effects to searches for axion Dark Matter on Earth. The finite momentum of axion Dark Matter is crucial to elucidating the effects of Earth on […]

Byzantine-Robust Federated Learning over Ring-All-Reduce Distributed Computing

Kavli Affiliate: Jia Liu | First 5 Authors: Minghong Fang, Zhuqing Liu, Xuecen Zhao, Jia Liu, | Summary: Federated learning (FL) has gained attention as a distributed learning paradigm for its data privacy benefits and accelerated convergence through parallel computation. Traditional FL relies on a server-client (SC) architecture, where a central server coordinates multiple clients […]
