Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, I. Adachi, H. Ahmed, Y. Ahn, H. Aihara | Summary: The Belle II experiment’s ability to identify particles critically affects the sensitivity of its measurements. We describe Belle II’s algorithms for identifying charged particles and evaluate their performance in separating pions, kaons, and protons […]
Kavli Affiliate: Jia Liu | First 5 Authors: Xiaohong Liu, Xiongkuo Min, Qiang Hu, Xiaoyun Zhang, Jie Guo | Summary: This paper reports on the NTIRE 2025 XGC Quality Assessment Challenge, which will be held in conjunction with the New Trends in Image Restoration and Enhancement Workshop (NTIRE) at CVPR 2025. This challenge is to […]
Kavli Affiliate: Jia Liu | First 5 Authors: Yang Bai, Ting-Kuo Chen, Jia Liu, Xiaolin Ma, | Summary: We present a complete Lagrangian describing axion interactions with pseudoscalar and (axial-)vector mesons within the three light-flavor quark framework. This formulation incorporates both the standard chiral Lagrangian and the full Wess-Zumino-Witten (WZW) term. By including instanton effects […]

Kavli Affiliate: Jia Liu | First 5 Authors: Junzhuo Li, Bo Wang, Xiuze Zhou, Peijie Jiang, Jia Liu | Summary: The interpretability of Mixture-of-Experts (MoE) models, especially those with heterogeneous designs, remains underexplored. Existing attribution methods for dense models fail to capture dynamic routing-expert interactions in sparse MoE architectures. To address this issue, we propose […]
Kavli Affiliate: Misao Sasaki | First 5 Authors: Diego Cruces, Shi Pi, Misao Sasaki, , | Summary: $delta N$ formalism is a useful method to calculate the curvature perturbation. Contrary to what it is typically done in the literature, we re-formulate the $delta N$ formalism by using the $e$-folding number $n$ counted forward in time. […]

Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Yuan Miao, Linhao Li, Hosho Katsura, Masahito Yamazaki, | Summary: Quantum many-body scars (QMBS) serve as important examples of ergodicity-breaking phenomena in quantum many-body systems. Despite recent extensive studies, exact QMBS are rare in dimensions higher than one. In this paper, we study a two-dimensional quantum $mathbb{Z}_2$ […]
Kavli Affiliate: Simeon Hellerman | First 5 Authors: Jahmall Bersini, Simeon Hellerman, Domenico Orlando, Susanne Reffert, | Summary: We study the fixed point of the three-dimensional NJL model in a double-scaling limit where both the charge $Q$ and the number of fermion flavors $N$ become large with a fixed ratio $q=Q/(2N)$. While a similar analysis […]
Kavli Affiliate: Yasunori Nomura | First 5 Authors: Yasunori Nomura, Tomonori Ugajin, , , | Summary: We study how meaningful physical predictions can arise in nonperturbative quantum gravity in a closed Lorentzian universe. In such settings, recent developments suggest that the quantum gravitational Hilbert space is one-dimensional and real for each $alpha$-sector, as induced by […]
