Kavli Affiliate: T. Higuchi | First 5 Authors: Belle, Belle II Collaborations, :, I. Adachi, L. Aggarwal | Summary: We report the result of a search for the rare decay $B^{0} to gamma gamma$ using a combined dataset of $753times10^{6}$ $Bbar{B}$ pairs collected by the Belle experiment and $387times10^{6}$ $Bbar{B}$ pairs collected by the Belle […]

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, I. Adachi, L. Aggarwal, H. Ahmed, H. Aihara | Summary: We report measurements of the $e^+e^- to Bbar{B}$, $Bbar{B}{}^*$, and $B^*bar{B}{}^*$ cross sections at four energies, 10653, 10701, 10746 and 10805 MeV, using data collected by the Belle~II experiment. We reconstruct one $B$ meson […]
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 […]
