Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: B. Theodore Zhang, Kohta Murase, Nick Ekanger, Mukul Bhattacharya, Shunsaku Horiuchi | Summary: We investigate the propagation of ultraheavy (UH) nuclei as ultrahigh-energy cosmic rays (UHECRs). We show that their energy loss lengths at $lesssim300$~EeV are significantly longer than those of protons and intermediate nuclei, and that […]

Kavli Affiliate: Yasunori Nomura | First 5 Authors: Benjamin Concepcion, Yasunori Nomura, Kyle Ritchie, Samuel Weiss, | Summary: Black hole complementarity posits that the interior of a black hole is not independent from its Hawking radiation. This leads to an apparent violation of causality: the interior can be acausally affected by operators acting solely on […]

Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Fumihiro Naokawa, Toshiya Namikawa, Kai Murai, Ippei Obata, Kohei Kamada | Summary: We point out that the rotation angle $beta$ of cosmic birefringence, which is a recently reported parity-violating signal in the cosmic microwave background (CMB), has a phase ambiguity of $npi ,(ninmathbb{Z})$. This ambiguity has a […]

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 […]
