Revisiting Big-Bang Nucleosynthesis Constraints on Long-Lived Decaying Particles
Masahiro Kawasaki, Kazunori Kohri, Takeo Moroi +1
We study effects of long-lived massive particles, which decay during the big-bang nucleosynthesis (BBN) epoch, on the primordial abundances of light elements. Compared to the previ…
State-of-the-Art Calculation of the Decay Rate of Electroweak Vacuum in Standard Model
So Chigusa, Takeo Moroi, Yutaro Shoji
The decay rate of the electroweak (EW) vacuum is calculated in the framework of the standard model (SM) of particle physics, using the recent progresses in the understanding of the…
False Vacuum Decay in Gauge Theory
Motoi Endo, Takeo Moroi, Mihoko M. Nojiri +1
The decay rate of a false vacuum is studied in gauge theory, paying particular attention to its gauge invariance. Although the decay rate should not depend on the gauge parameter $…
On the Gauge Invariance of the Decay Rate of False Vacuum
Motoi Endo, Takeo Moroi, Mihoko M. Nojiri +1
We study the gauge invariance of the decay rate of the false vacuum for the model in which the scalar field responsible for the false vacuum decay has gauge quantum number. In orde…
Extending the LHC Reach for New Physics with Sub-Millimeter Displaced Vertices
Hayato Ito, Osamu Jinnouchi, Takeo Moroi +2
Particles with a sub-millimeter decay length appear in many models of physics beyond the Standard Model. However, their longevity has been often ignored in their LHC searches and t…
Bottom-Tau Unification in Supersymmetric SU(5) Models with Extra Matters
So Chigusa, Takeo Moroi
We consider - unification in supersymmetric grand unified theories (GUTs) with extra matters. The renormalization group runnings of and Yukawa coupling consta…
