Kavli Affiliate: Satoshi Shirai | First 5 Authors: Gonzalo Herrera, Alejandro Ibarra, Satoshi Shirai, , | Summary: In some scenarios, the dark matter particle predominantly scatters inelastically with the target, producing a heavier neutral particle in the final state. In this class of scenarios, the reach in parameter space of direct detection experiments is limited […]
Kavli Affiliate: Taizan Watari | First 5 Authors: Masaki Okada, Taizan Watari, , , | Summary: A characterization of rational superconformal field theories (SCFTs) on 1+1 dimensions with Ricci-flat Kahler targets was proposed by S. Gukov and C. Vafa in terms of the Hodge structure of the target space. The article [arXiv:2205.10299] refined this idea […]
Kavli Affiliate: Masahiro Takada | First 5 Authors: Tianqing Zhang, Xiangchong Li, Roohi Dalal, Rachel Mandelbaum, Michael A. Strauss | Summary: Cosmological weak lensing measurements rely on a precise measurement of the shear two-point correlation function (2PCF) along with a deep understanding of systematics that affect it. In this work, we demonstrate a general framework […]
Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, I. Adachi, K. Adamczyk, L. Aggarwal, H. Ahmed | Summary: The $L_{mu}-L_{tau}$ extension of the standard model predicts the existence of a lepton-flavor-universality-violating $Z^{prime}$ boson that couples only to the heavier lepton families. We search for such a $Z^prime$ through its invisible decay in […]
Kavli Affiliate: Masahiro Takada | First 5 Authors: Markus Michael Rau, Roohi Dalal, Tianqing Zhang, Xiangchong Li, Atsushi J. Nishizawa | Summary: We present posterior sample redshift distributions for the Hyper Suprime-Cam Subaru Strategic Program Weak Lensing three-year (HSC Y3) analysis. Using the galaxies’ photometry and spatial cross-correlations, we conduct a combined Bayesian Hierarchical Inference […]
Kavli Affiliate: Simeon Hellerman | First 5 Authors: Nicola Dondi, Simeon Hellerman, Ioannis Kalogerakis, Rafael Moser, Domenico Orlando | Summary: We study the large-charge sector of large-N fermionic CFTs in three dimensions. Depending on the model and the nature of the fixed charge, we find two types of descriptions: in terms of a superfluid or […]

Kavli Affiliate: John D. Silverman | First 5 Authors: Xuheng Ding, Masafusa Onoue, John D. Silverman, Yoshiki Matsuoka, Takuma Izumi | Summary: The detection of starlight from the host galaxies of quasars during the reionization epoch ($z>6$) has been elusive, even with deep HST observations. The current highest redshift quasar host detected, at $z=4.5$, required […]

Kavli Affiliate: Misao Sasaki | First 5 Authors: Shi Pi, Misao Sasaki, , , | Summary: We study the comoving curvature perturbation $mathcal{R}$ in the single-field inflation models whose potential can be approximated by a piecewise quadratic potential $V(varphi)$ by using the $delta N$ formalism. We find a general formula for $mathcal{R}(deltavarphi, deltapi)$, consisting of […]
