Stringent Constraints on Self-Interacting Dark Matter Using Milky-Way Satellite Galaxies Kinematics

Kavli Affiliate: Satoshi Shirai | First 5 Authors: Shin’ichiro Ando, Kohei Hayashi, Shunichi Horigome, Masahiro Ibe, Satoshi Shirai | Summary: Self-interacting dark matter (SIDM) has been proposed to address small-scale challenges faced by the cold dark matter (CDM) paradigm, such as the diverse density profiles observed in dwarf galaxies. In this study, we analyze the […]

Long-lived Light Mediators in a Higgs Portal Model at the FCC-ee

Kavli Affiliate: Shigeki Matsumoto | First 5 Authors: Biplob Bhattacherjee, Camellia Bose, Herbi K. Dreiner, Nivedita Ghosh, Shigeki Matsumoto | Summary: In the search for beyond the Standard Model (SM) physics, long-lived particles (LLPs) have emerged as potential candidates and are being explored in various ongoing experiments. Future lepton colliders, such as the FCC-ee, shall […]

Exact Results in Chiral Gauge Theories with Flavor

Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Jacob M. Leedom, Hitoshi Murayama, Gup Singh, Bethany Suter, Jason Wong | Summary: We present exact results in $text{SU}(N_C)$ chiral gauge theories with charged fermions in an antisymmetric, $N_F$ fundamental, and $N_C + N_F – 4$ anti-fundamental representations. We achieve this by considering the supersymmetric version of […]

Searching for Exotic Interactions between Antimatter

Kavli Affiliate: Yevgeny V. Stadnik | First 5 Authors: Lei Cong, Filip Ficek, Pavel Fadeev, Yevgeny V. Stadnik, Dmitry Budker | Summary: We show that atomic antimatter spectroscopy can be used to search for new bosons that carry spin-dependent exotic forces between antifermions. A comparison of a recent precise measurement of the hyperfine splitting of […]

$K$-theoretic pullbacks for Lagrangians on derived critical loci

Kavli Affiliate: Yukinobu Toda | First 5 Authors: Yalong Cao, Yukinobu Toda, Gufang Zhao, , | Summary: Given a regular function $phi$ on a smooth stack, and a $(-1)$-shifted Lagrangian $M$ on the derived critical locus of $phi$, under fairly general hypotheses, we construct a pullback map from the Grothendieck group of coherent matrix factorizations […]

Every FLOP Counts: Scaling a 300B Mixture-of-Experts LING LLM without Premium GPUs

Kavli Affiliate: Jia Liu | First 5 Authors: Ling Team, Binwei Zeng, Chao Huang, Chao Zhang, Changxin Tian | Summary: In this technical report, we tackle the challenges of training large-scale Mixture of Experts (MoE) models, focusing on overcoming cost inefficiency and resource limitations prevalent in such systems. To address these issues, we present two […]
