O() Invariance of the Multi-Field Bounce
Kfir Blum, Masazumi Honda, Ryosuke Sato +2
In his 1977 paper on vacuum decay in field theory: The Fate of the False Vacuum, Coleman considered the problem of a single scalar field and assumed that the minimum action tunnell…
LHC Future Prospects of the 750 GeV Resonance
Ryosuke Sato, Kohsaku Tobioka
A quantitative discussion on the future prospects of the 750 GeV resonance at the LHC experiment is given using a simple effective field theory analysis. The relative size of two e…
Self-consistent Calculation of the Sommerfeld Enhancement
Kfir Blum, Ryosuke Sato, Tracy R. Slatyer
A calculation of the Sommerfeld enhancement is presented and applied to the problem of s-wave non-relativistic dark matter annihilation. The difference from previous computations i…
Composite Accidental Axions
Michele Redi, Ryosuke Sato
We present several models where the QCD axion arises accidentally. Confining gauge theories can generate axion candidates whose properties are uniquely determined by the quantum nu…
