Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Gonzalo Herrera, Shunsaku Horiuchi, Xiaolin Qi, , | Summary: Energetic cosmic rays scatter off the cosmic neutrino background throughout the history of the Universe, yielding a diffuse flux of cosmic relic neutrinos boosted to high energies. We calculate this flux under different assumptions of the cosmic-ray flux […]

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, I. Adachi, K. Adamczyk, L. Aggarwal, H. Aihara | Summary: We present a measurement of the ratio $R_mu = mathcal{B}(tau^-to mu^-barnu_munu_tau) / mathcal{B}(tau^-to e^-barnu_enu_tau)$ of branching fractions $mathcal{B}$ of the $tau$ lepton decaying to muons or electrons using data collected with the Belle II […]

Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Emilie Hertig, Kevin Wolz, Toshiya Namikawa, Antón Baleato Lizancos, Susanna Azzoni | Summary: The Simons Observatory (SO), a next-generation ground-based CMB experiment in its final stages of construction, will target primordial $B$-modes with unprecedented sensitivity to set tight bounds on the amplitude of inflationary gravitational waves. Aiming […]
Kavli Affiliate: Jia Liu | First 5 Authors: Adrian E. Bayer, Jia Liu, Christina D. Kreisch, Alice Pisani, | Summary: Massive neutrinos suppress the growth of cosmic structure on nonlinear scales, motivating the use of information beyond the power spectrum to tighten constraints on the neutrino mass, for example by considering cosmic voids. It was […]

Kavli Affiliate: Jia Liu | First 5 Authors: Haipeng An, Shuailiang Ge, Jia Liu, Mingzhe Liu, | Summary: Dark photon dark matter emerges as a compelling candidate for ultralight bosonic dark matter, detectable through resonant conversion into photons within a plasma environment. This study employs in-situ measurements from the Parker Solar Probe (PSP), the first […]
Kavli Affiliate: Jia Liu | First 5 Authors: Yue Chen, Chen Huang, Yang Deng, Wenqiang Lei, Dingnan Jin | Summary: Equipping a conversational search engine with strategies regarding when to ask clarification questions is becoming increasingly important across various domains. Attributing to the context understanding capability of LLMs and their access to domain-specific sources of […]
Kavli Affiliate: Misao Sasaki | First 5 Authors: Qiuyue Liang, Ippei Obata, Misao Sasaki, , | Summary: The positive evidence of a nano-hertz gravitational wave background recently found by several pulsar timing array (PTA) collaborations opened up a window to test modified gravity theories in a unique frequency band in parallel to other gravitational wave […]
