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 […]

Cosmological Consequences of Domain Walls Biased by Quantum Gravity

Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Yann Gouttenoire, Stephen F. King, Rishav Roshan, Xin Wang, Graham White | Summary: One of the simplest standard model extensions leading to a domain wall network is a real scalar $S$ with a $mathcal{Z}_2$ symmetry spontaneously broken during universe evolution. Motivated by the swampland program, we explore […]

Three-dimensional core-collapse supernova models with phenomenological treatment of neutrino flavor conversions

Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Kanji Mori, Tomoya Takiwaki, Kei Kotake, Shunsaku Horiuchi, | Summary: We perform three-dimensional supernova simulations with a phenomenological treatment of neutrino flavor conversions. We show that the explosion energy can increase to as high as ~10^51 erg depending on the critical density for the onset of flavor […]

On the equivalence between galaxy angular correlation function and power spectrum in constraining primordial non-Gaussianity

Kavli Affiliate: Masahiro Takada | First 5 Authors: Ryo Terasawa, Yue Nan, Masahiro Takada, , | Summary: We investigate the angular power spectrum ($C_ell)$ and angular correlation function ($w(theta)$) of galaxy number density field in the presence of the local-type primordial non-Gaussianity (PNG), explicitly accounting for the integral constraint in an all-sky survey. We show […]
