Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Hitoshi Murayama, Bea Noether, Jan Schütte-Engel, , | Summary: Leptogenesis is arguably the best motivated theory of baryogenesis given the discovery of finite neutrino masses, yet its experimental test is elusive given its high energy scale. We discuss gravitational waves (GWs) produced via graviton bremsstrahlung in right-handed […]
Kavli Affiliate: Toshiyuki Kobayashi | First 5 Authors: Toshiyuki Kobayashi, , , , | Summary: This exposition presents recent developments on proper actions, highlighting their connections to representation theory. It begins with geometric aspects, including criteria for the properness of homogeneous spaces in the setting of reductive groups. We then explore the interplay between the […]
Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, I. Adachi, K. Adamczyk, L. Aggarwal, H. Ahmed | Summary: We present a determination of the Cabibbo-Kobayashi-Maskawa matrix element $|V_{cb}|$ from the decay $Bto Dellnu_ell$ using a $365~mathrm{fb}^{-1}$ $e^+e^-toUpsilon(4S)to Bbar B$ data sample recorded by the Belle II experiment at the SuperKEKB collider. The […]
Kavli Affiliate: Satoshi Shirai | First 5 Authors: Akifumi Chitose, Masahiro Ibe, Satoshi Shirai, Yaxuan Wen, | Summary: We investigate cosmic strings arising from a hierarchical gauge symmetry breaking sequence, $mathrm{SU}(2) times mathrm{U}(1) rightarrow mathrm{U}(1) times mathrm{U}(1) rightarrow mathrm{U}(1)’ rightarrow text{Nothing}$. This pattern gives rise to two distinct classes of cosmic strings: light, stable strings […]
Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Csaba Csáki, Teruhiko Kawano, Hitoshi Murayama, Ofri Telem, | Summary: We calculate the $theta$ dependence in a cousin of QCD, where the vacuum structure can be analyzed exactly. The theory is $mathcal{N}=2$ $SU(2)$ gauge theory with $N_F=0,1,2,3$ flavors of fundamentals, explicitly broken to $mathcal{N}=1$ via an adjoint […]
Kavli Affiliate: Tomotake Matsumura | First 5 Authors: Shaul Hanany, Scott Cray, Samuel Dietterich, Jan Dusing, Calvin Firth | Summary: We used laser ablation to fabricate sub-wavelength structure anti-reflection coating (SWS-ARC) on a 5 cm diameter alumina lens. With an aspect ratio of 2.5, the SWS-ARC are designed to give a broad-band low reflectance response […]

Kavli Affiliate: Jia Liu | First 5 Authors: Tengyu Ai, Qi Bi, Yuxin He, Jia Liu, Xiao-Ping Wang | Summary: We investigate whether collider experiments can reach the quantum limit of precision, defined by the quantum Fisher information (QFI), using only classical observables such as particle momenta. As a case study, we focus on the […]
Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Mayank Sharma, Gonzalo Herrera, Nahum Arav, Shunsaku Horiuchi, | Summary: We propose a new method to determine the dark matter density profile in the vicinity of distant supermassive black holes (SMBH) using reverberation mapping measurements of active galactic nuclei (AGN). For some AGN, the mapping of multiple […]
Kavli Affiliate: Jia Liu | First 5 Authors: Wenhan Yao, Fen Xiao, Xiarun Chen, Jia Liu, YongQiang He | Summary: As a foundational technology for intelligent human-computer interaction, voice conversion (VC) seeks to transform speech from any source timbre into any target timbre. Traditional voice conversion methods based on Generative Adversarial Networks (GANs) encounter significant […]
