Kavli Affiliate: Simeon Hellerman | First 5 Authors: Matthew Dodelson, Simeon Hellerman, Masataka Watanabe, Masahito Yamazaki, | Summary: It is shown that integrability is an accidental property of generic two-dimensional $O(2)$-symmetric asymptotically-free theories in the regime where the charge density is much larger than the dynamical scale. We show this by constructing an infinite tower […]
Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, I. Adachi, K. Adamczyk, L. Aggarwal, H. Aihara | Summary: We determine the CKM matrix-element magnitude $|V_{cb}|$ using $overline{B}^0to D^{*+}ell^-barnu_ell$ decays reconstructed in $189 , mathrm{fb}^{-1}$ of collision data collected by the Belle II experiment, located at the SuperKEKB $e^+e^-$ collider. Partial decay rates […]

Kavli Affiliate: Jia Liu | First 5 Authors: Zitong Xu, Xiaolin Ma, Kai Wei, Yuxuan He, Xing Heng | Summary: Experiments aimed at detecting ultralight dark matter typically rely on resonant effects, which are sensitive to the dark matter mass that matches the resonance frequency. In this study, we investigate the nucleon couplings of ultralight […]

Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Ziyang Chen, Drew Jamieson, Eiichiro Komatsu, Sownak Bose, Klaus Dolag | Summary: The statistics of thermal gas pressure are a new and promising probe of cosmology and astrophysics. The large-scale cross-correlation between galaxies and the thermal Sunyaev-Zeldovich effect gives the bias-weighted mean electron pressure, $langle b_mathrm{h}P_erangle$. In […]
Kavli Affiliate: John D. Silverman | First 5 Authors: Kiyoaki Christopher Omori, Connor Bottrell, Mike Walmsley, Hassen M. Yesuf, Andy D. Goulding | Summary: We take a deep learning-based approach for galaxy merger identification in Subaru HSC-SSP, specifically through the use of deep representation learning and fine-tuning, with the aim of creating a pure and […]
Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Meer Ashwinkumar, Jun-ichi Sakamoto, Masahito Yamazaki, , | Summary: We elucidate the relationship between 2d integrable field theories and 2d integrable lattice models, in the framework of the 4d Chern-Simons theory. The 2d integrable field theory is realized by coupling the 4d theory to multiple 2d surface […]
Kavli Affiliate: Misao Sasaki | First 5 Authors: Kaloian D. Lozanov, Misao Sasaki, Volodymyr Takhistov, , | Summary: Causal soliton formation (e.g. oscillons, Q-balls) in the primordial Universe is expected to give rise to a universal gravitational wave (GW) background, at frequencies smaller than scales of nonlinearity. We show that modifications of the soliton density […]
