Kavli Affiliate: Satoshi Shirai | First 5 Authors: Akifumi Chitose, Masahiro Ibe, Shunsuke Neda, Satoshi Shirai, | Summary: Recent observations by pulsar timing arrays (PTAs) indicate a potential detection of a stochastic gravitational wave (GW) background. Metastable cosmic strings have been recognized as a possible source of the observed signals. In this paper, we propose […]

Kavli Affiliate: Mihoko M. Nojiri | First 5 Authors: A. Hammad, Mihoko M Nojiri, , , | Summary: In this article, we review recent machine learning methods used in challenging particle identification of heavy-boosted particles at high-energy colliders. Our primary focus is on attention-based Transformer networks. We report the performance of state-of-the-art deep learning networks […]
Kavli Affiliate: Misao Sasaki | First 5 Authors: Misao Sasaki, Vicharit Yingcharoenrat, Ying-li Zhang, , | Summary: In the absence of gravity, Coleman’s theorem states that the $O(4)$-symmetric instanton solution, which is regular at the origin and exponentially decays at infinity, gives the lowest action. Perturbatively, this implies that any small deformation from $O(4)$-symmetry gives […]

Kavli Affiliate: Jia Liu | First 5 Authors: Ruijun Zhang, Mingkun Zhang, Guoliang Zhang, Yujian Chen, Jia Liu | Summary: A minority carrier lifetime of 25.46 $mu$s in a P-type 4H-SiC epilayer has been attained through sequential thermal oxidation and hydrogen annealing. Thermal oxidation can enhance the minority carrier lifetime in the 4H-SiC epilayer by […]
Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, I. Adachi, L. Aggarwal, H. Ahmed, H. Aihara | Summary: We present measurements of $B to K{}^{*}(892)gamma$ decays using $365,{rm fb}^{-1}$ of data collected from 2019 to 2022 by the Belle~II experiment at the SuperKEKB asymmetric-energy $e^+e^-$ collider. The data sample contains $(387 pm […]
Kavli Affiliate: Masahito Yamazaki | First 5 Authors: A. Hammad, Mihoko M. Nojiri, Masahito Yamazaki, , | Summary: Anomaly detection is a vital technique for exploring signatures of new physics Beyond the Standard Model (BSM) at the Large Hadron Collider (LHC). The vast number of collisions generated by the LHC demands sophisticated deep learning techniques. […]

Kavli Affiliate: Hirosi Ooguri | First 5 Authors: Yuya Kusuki, Sara Murciano, Hirosi Ooguri, Sridip Pal, | Summary: A state in a quantum system with a given global symmetry, $G$, can be sensitive to the presence of boundaries, which may either preserve or break this symmetry. In this work, we investigate how conformal invariant boundary […]
