High energy particle collisions in static, spherically symmetric black-hole-like wormholes
Naoki Tsukamoto, Takafumi Kokubu
A Damour-Solodukhin wormhole with a metric which is similar to a Schwarzschild black hole seems to be a black hole mimicker since it is difficult to distinguish them by practical a…
Self-assembled structure of dendronized CdS nanoparticles
Hiroshi Nakajima, Daichi Matsuki, Yumi Fukunaga +6
Self-assembled dendronized CdS nanoparticles have been attracting considerable attention because of their photoluminescence properties depending on annealing treatments. In this st…
A Significant Feature in the General Relativistic Time Evolution of the Redshift of Photons Coming from a Star Orbiting Sgr A*
Hiromi Saida, Shogo Nishiyama, Takayuki Ohgami +16
The star S0-2, orbiting the Galactic central massive black hole candidate Sgr A*, passed its pericenter in May 2018. This event is the first chance to detect the general relativist…
H-COUP Version 2: a program for one-loop corrected Higgs boson decays in non-minimal Higgs sectors
Shinya Kanemura, Mariko Kikuchi, Kentarou Mawatari +2
We present the concept of H-COUP_ver 2, which evaluates the decay rates (including higher order corrections) for the Higgs boson with a mass of 125 GeV in various extended Higgs mo…
Universal Upper Bound on the Inflationary Energy Scale from the Trans-Planckian Censorship Conjecture
Shuntaro Mizuno, Shinji Mukohyama, Shi Pi +1
We study the constraint on the inflationary energy scale from the recently proposed Trans-Planckian Censorship Conjecture (TCC). We find a universal upper bound on the inflationary…
Primordial Tensor Non-Gaussianity from Massive Gravity
Tomohiro Fujita, Shuntaro Mizuno, Shinji Mukohyama
We calculate tensor bispectrum in a theory of massive tensor gravitons which predicts blue-tilted and largely amplified primordial gravitational waves. We find that a new 3-point i…
