Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Tony Gherghetta, Hitoshi Murayama, Pablo Quílez, , | Summary: We present a composite QCD axion model where the Peccei–Quinn (PQ) symmetry emerges as a high-quality, accidental symmetry. The axion potential is only modified by eight-fermion, dimension 12 operators, which if present at the Planck scale, allow for […]
Kavli Affiliate: T. Higuchi | First 5 Authors: Belle, Belle II Collaborations, :, I. Adachi, Y. Ahn | Summary: We present the results of a search for the charged-lepton-flavor violating decays $B^0 rightarrow K^{*0}tau^pm ell^{mp}$, where $ell^{mp}$ is either an electron or a muon. The results are based on 365 fb$^{-1}$ and 711 fb$^{-1}$ datasets […]
Kavli Affiliate: Tom Melia | First 5 Authors: David E. Kaplan, Tom Melia, Surjeet Rajendran, , | Summary: Three possible strategies have been advocated to solve the strong CP problem. The first is the axion, a dynamical mechanism that relaxes any initial value of the CP violating angle $bar{theta}$ to zero. The second is the […]
Kavli Affiliate: Claudio Ricci | First 5 Authors: Alessandro Peca, Michael J. Koss, Roberto Serafinelli, Claudio Ricci, C. Megan Urry | Summary: We report the serendipitous discovery of an absorption feature at 4.8 keV in the NuSTAR spectra of ESP 39607, a Seyfert 2 galaxy at $z = 0.201$, observed in May 2023 and August […]
Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Saghar S. Hosseini, Yuji Tachikawa, Hao Y. Zhang, , | Summary: We revisit the issue of how the perturbative and global fermion anomaly of Type I string theory in ten dimensions is cancelled by the Green-Schwarz mechanism using the RR fields. This will be done by realising […]
Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Andrew Goh, Hitoshi Murayama, Gup Singh, Bethany Suter, Jason Wong | Summary: We present exact non-perturbative solutions to chiral gauge theories based on the $E_6$ gauge group and several matter fermions in the fundamental $bf{27}$-dimensional representation. They are obtained when supersymmetric versions are perturbed by small supersymmetry […]
Kavli Affiliate: Lina Necib | First 5 Authors: Dylan Folsom, Carlos Blanco, Mariangela Lisanti, Lina Necib, Mark Vogelsberger | Summary: The sensitivity of direct detection experiments depends on the phase-space distribution of dark matter near the Sun, which can be modeled theoretically using cosmological hydrodynamical simulations of Milky Way-like galaxies. However, capturing the halo-to-halo variation […]
Kavli Affiliate: Feng Yuan | First 5 Authors: Feng Yuan, Yifan Gao, Wenbin Wu, Keqing Wu, Xiaotong Guo | Summary: Accurate multi-modal medical image translation requires ha-rmonizing global anatomical semantics and local structural fidelity, a challenge complicated by intermodality information loss and structural distortion. We propose ABS-Mamba, a novel architecture integrating the Segment Anything Model […]
Kavli Affiliate: Rainer Spurzem | First 5 Authors: Marcelo C. Vergara, Abbas Askar, Albrecht W. H. Kamlah, Rainer Spurzem, Francesco Flammini Dotti | Summary: Context. We present simulations of a massive young star cluster using textsc{Nbody6++GPU} and textsc{MOCCA}. The cluster is initially more compact than previously published models, with one million stars, a total mass […]
Kavli Affiliate: Luis C. Ho | First 5 Authors: Zhicheng He, Enci Wang, Luis C. Ho, Huiyuan Wang, Yong Shi | Summary: The Star-Forming Main Sequence (SFMS) serves as a critical framework for understanding galaxy evolution, highlighting the relationship between star formation rates (SFR) and stellar masses M_* across cosmic time. Despite its significance, the […]
