Determination of $|V_{ub}|$ from simultaneous measurements of untagged $B^0toπ^- ell^+ ν_{ell}$ and $B^+toρ^0 ell^+ν_{ell}$ decays

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, I. Adachi, L. Aggarwal, H. Aihara, N. Akopov | Summary: We present a measurement of $|V_{ub}|$ from a simultaneous study of the charmless semileptonic decays $B^0topi^- ell^+ nu_{ell}$ and $B^+torho^0 ell^+nu_{ell}$, where $ell = e, mu$. This measurement uses a data sample of 387 […]

Unveiling In-Situ Spheroid Formation in Distant, Submillimeter-Bright Galaxies

Kavli Affiliate: John D. Silverman | First 5 Authors: Qing-Hua Tan, Emanuele Daddi, Benjamin Magnelli, Camila A. Correa, Frédéric Bournaud | Summary: The majority of stars in today’s Universe reside within spheroids, which are bulges of spiral galaxies and elliptical galaxies. Their formation is still an unsolved problem. Infrared/submm-bright galaxies at high redshifts have long […]

Particle Conversions Beyond the WKB Approximation and Solar-Induced Gravitational Waves from Dark Photon Dark Matter

Kavli Affiliate: Jia Liu | First 5 Authors: Tengyu Ai, Yuxuan He, Jia Liu, Xiaolin Ma, Xiao-Ping Wang | Summary: We investigate the conversion of kinetic mixing dark photon dark matter into gravitational waves within the magnetic field of the Sun. Our study reveals that the WKB approximation is invalid in this scenario. We derive […]

Rich and diverse molecular gas environments of closely-separated dual quasars viewed by ALMA

Kavli Affiliate: John D. Silverman | First 5 Authors: Shenli Tang, John D. Silverman, Zhaoxuan Liu, Manda Banerji, Tomoko Suzuki | Summary: We present a study of the molecular gas in five closely-spaced ($R_{perp}<20$ kpc) dual quasars ($L_{rm bol}gtrsim10^{44}~mathrm{erg~s}^{-1}$) at redshifts $0.4<z<0.8$ with the Atacama Large Millimeter/submillimeter Array. The dual quasar phase represents a distinctive […]
