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

Posted by dbos Tokyo

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 […]

CMB-S4: Foreground-Cleaning Pipeline Comparison for Measuring Primordial Gravitational Waves

Posted by klaurent Stanford

Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Federico Bianchini, Dominic Beck, W. L. Kimmy Wu, Zeeshan Ahmed, Sebastian Belkner | Summary: We compare multiple foreground-cleaning pipelines for estimating the tensor-to-scalar ratio, $r$, using simulated maps of the planned CMB-S4 experiment within the context of the South Pole Deep Patch. To evaluate robustness, we analyze […]

Ruling out AGNs as the dominant source of cosmic reionization with JWST

Posted by dbos Peking

Kavli Affiliate: Linhua Jiang | First 5 Authors: Danyang Jiang, Linhua Jiang, Shengxiu Sun, Weiyang Liu, Shuqi Fu | Summary: Cosmic reionization represents the latest phase transition of the intergalactic medium (IGM) in the Universe. It has long been debated whether galaxies or active galactic nuclei (AGNs) are the major source of Lyman continuum (LyC) […]
