Black Hole and de Sitter Microstructures from a Semiclassical Perspective

Kavli Affiliate: Yasunori Nomura | First 5 Authors: Chitraang Murdia, Yasunori Nomura, Kyle Ritchie, , | Summary: We describe two different, but equivalent semiclassical views of black hole physics in which the equivalence principle and unitarity are both accommodated. In one, unitarity is built-in, while the black hole interior emerges only effectively as a collective […]

Search for a dark photon and an invisible dark Higgs boson in $μ^+μ^-$ and missing energy final states with the Belle II experiment

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, F. Abudinén, I. Adachi, L. Aggarwal, H. Aihara | Summary: The dark photon $A^prime$ and the dark Higgs boson $h^prime$ are hypothetical particles predicted in many dark sector models. We search for the simultaneous production of $A^prime$ and $h^prime$ in the dark Higgsstrahlung process […]

A universal formula for the density of states with continuous symmetry

Kavli Affiliate: Hirosi Ooguri | First 5 Authors: Monica Jinwoo Kang, Jaeha Lee, Hirosi Ooguri, , | Summary: We consider a $d$-dimensional unitary conformal field theory with a compact Lie group global symmetry $G$ and show that, at high temperature $T$ and on a compact Cauchy surface, the probability of a randomly chosen state being […]

Time-varying resonant mass at collider and beam dump experiments

Kavli Affiliate: Jia Liu | First 5 Authors: Jinhui Guo, Yuxuan He, Jia Liu, Xiao-Ping Wang, Ke-Pan Xie | Summary: A new particle usually manifests itself as a single resonant peak located at its mass. We propose if the new particle mass is time-varying due to environmental effects, then its mass spectrum typically has a […]

Unveiling Time-Varying Signals of Ultralight Bosonic Dark Matter at Collider and Beam Dump Experiments

Kavli Affiliate: Jia Liu | First 5 Authors: Jinhui Guo, Yuxuan He, Jia Liu, Xiao-Ping Wang, Ke-Pan Xie | Summary: The ultralight boson represents a promising dark matter candidate exhibiting unique wave-like behaviors. These properties could transfer to the dark mediator, such as the kinetic mixing dark photon, which can be a link between the […]

First Evaluation of Meson and $τ$ lepton Spectra and Search for Heavy Neutral Leptons at ILC Beam Dump

Kavli Affiliate: Mihoko M. Nojiri | First 5 Authors: Mihoko M. Nojiri, Yasuihito Sakaki, Kohsaku Tobioka, Daiki Ueda, | Summary: A beam dump experiment can be seamlessly added to the {proposed} International Linear Collider (ILC) program because the high energy electron beam should be dumped after the collision point. The ILC beam dump experiment will […]
