Chiral perturbative analysis for an almost massless neutrino in the type-I seesaw mechanism
Masaki J. S. Yang
In this paper, we perform chiral perturbative analysis of an approximate lepton number symmetry associated with a sufficiently light neutrino in the type-I seesaw mechanism. For th…
XMM-Newton view of the shock heating in an early merging cluster, CIZA J1358.94750
Y. Omiya, K. Nakazawa, K. Matsushita +10
CIZA J1358.9-4750 is a nearby galaxy cluster in the early phase of a major merger. The two-dimensional temperature map using XMM-Newton EPIC-PN observation confirms the existence o…
Vibration characteristics of a continuously rotating superconducting magnetic bearing and potential influence to TES and SQUID
Shinya Sugiyama, Tommaso Ghigna, Yurika Hoshino +9
We measured the vibration of a prototype superconducting magnetic bearing (SMB) operating at liquid nitrogen temperature. This prototype system was designed as a breadboard model f…
Constraints on the nuclear Schiff moment from its correlation with electromagnetic properties
K. Yanase, N. Shimizu, K. Higashiyama +1
We study the nuclear Schiff moments of Xe and Hg induced by the nucleon electric dipole moment using large-scale shell model calculations. For Xe, we find a…
Spin current and chirality degrees of freedom inherent in localized electron orbitals
Shintaro Hoshino, Michi-To Suzuki, Hiroaki Ikeda
In solid state physics, any phase transition is commonly observed as a change in the microscopic distribution of charge, spin, or current. Here we report the nature of an exotic or…
Multiscale space-time ansatz for correlation functions of quantum systems based on quantics tensor trains
Hiroshi Shinaoka, Markus Wallerberger, Yuta Murakami +4
Correlation functions of quantum systems -- central objects in quantum field theories -- are defined in high-dimensional space-time domains. Their numerical treatment thus suffers…
Search for Lepton Flavor Violating Decay at FASER
Takeshi Araki, Kento Asai, Hidetoshi Otono +2
FASER is one of the promising experiments which search for long-lived particles beyond the Standard Model. In this paper, we consider charged lepton flavor violation (CLFV) via a l…
The Obscured Fraction of Quasars at Cosmic Noon
Bovornpratch Vijarnwannaluk, Masayuki Akiyama, Malte Schramm +6
Statistical studies of X-ray selected Active Galactic Nuclei (AGN) indicate that the fraction of obscured AGN increases with increasing redshift, and the results suggest that a sig…
Asymmetric Mediator in Scotogenic Model
Kento Asai, Yuhei Sakai, Joe Sato +2
The scotogenic model is the Standard Model (SM) with Z_2 symmetry and the addition of Z_2 odd right-handed Majorana neutrinos and SU(2)_L doublet scalar fields. We have extended th…
-defined Isochronous Mass Spectrometry and Mass Measurements of Ni Fragments
M. Zhang, X. Zhou, M. Wang +25
A novel isochronous mass spectrometry, termed as -defined IMS, is established at the experimental cooler-storage ring CSRe in Lanzhou. Its potential has been studied through hi…
Del Pezzo quintics as equivariant compactifications of vector groups
Adrien Dubouloz, Takashi Kishimoto, Pedro Montero
We study faithful actions with a dense orbit of abelian unipotent groups on quintic del Pezzo varieties over a field of characteristic zero. Such varieties are forms of linear sect…
