Measurement of the branching fractions and $CP$ asymmetries of $B^+ rightarrow π^+ π^0$ and $B^+ rightarrow K^+ π^0$ decays in 2019-2021 Belle II data

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, F. Abudinén, I. Adachi, K. Adamczyk, L. Aggarwal | Summary: We determine the branching fractions ${mathcal{B}}$ and $CP$ asymmetries ${mathcal{A}_{{it CP}}}$ of the decays $B^+ rightarrow pi^+ pi^0$ and $B^+ rightarrow K^+ pi^0$. The results are based on a data set containing 198 million […]

Gravitational waves from rapid structure formation on microscopic scales before matter-radiation equality

Kavli Affiliate: Misao Sasaki | First 5 Authors: Marcos M. Flores, Alexander Kusenko, Misao Sasaki, , | Summary: The existence of scalar fields can be probed by observations of stochastic gravitational waves. Scalar fields mediate attractive forces, usually stronger than gravity, on the length scales shorter than their Compton wavelengths, which can be non-negligible in […]

The MegaMapper: A Stage-5 Spectroscopic Instrument Concept for the Study of Inflation and Dark Energy

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: David J. Schlegel, Juna A. Kollmeier, Greg Aldering, Stephen Bailey, Charles Baltay | Summary: In this white paper, we present the MegaMapper concept. The MegaMapper is a proposed ground-based experiment to measure Inflation parameters and Dark Energy from galaxy redshifts at $2<z<5$. In order to achieve […]

Polarization effects on fluorescence emission of zebrafish neurons using light-sheet microscopy

Kavli Affiliate: Jing Wang | First 5 Authors: Hong Ye, Xin Xu, Jixiang Wang, Jing Wang, Yi He | Summary: Light-sheet fluorescence microscopy (LSFM) makes use of a thin plane of light to optically section and image transparent tissues or organisms {it{in vivo}}, which has the advantages of fast imaging speed and low phototoxicity. In […]
