Dark baryon from pure Yang-Mills theory and its GW signature from cosmic strings
Masaki Yamada, Kazuya Yonekura
We point out that SO() pure Yang-Mills theory provides a candidate for dark matter (DM) without the explicit need to impose any additional symmetry. The DM candidate is a parti…
SIMP from a strong U(1) gauge theory with a monopole condensation
Ayuki Kamada, Masaki Yamada, Tsutomu T. Yanagida +1
We provide a variant model of strongly interacting massive particle (SIMP), where composite dark matter comes from a strongly interacting U(1) theory. We first explain a non-Abelia…
Diphoton Excess as a Hidden Monopole
Masaki Yamada, Tsutomu T. Yanagida, Kazuya Yonekura
We provide a theory with a monopole of a strongly-interacting hidden U(1) gauge symmetry that can explain the 750-GeV diphoton excess reported by ATLAS and CMS. The excess results…
Gravity Mediation of Supersymmetry Breaking with Dynamical Metastability
K. -I. Izawa, Fuminobu Takahashi, T. T. Yanagida +1
We argue that the Polonyi problem can be avoided when our supersymmetry-breaking vacuum is surrounded by many supersymmetric vacua. We construct a dynamical class of supersymmetry-…
Gauge Mediation with Sequestered Supersymmetry Breaking
Satoshi Shirai, Fuminobu Takahashi, T. T. Yanagida +1
Gauge mediation models have two drawbacks, that is, the so-called μ-problem and a lack of predictability of the gravitino dark matter abundance. We show that conformal sequestering…
Gravitational Waves as a Probe of the Gravitino Mass
Fuminobu Takahashi, T. T. Yanagida, Kazuya Yonekura
If gaugino condensations occur in the early universe, domain walls are produced as a result of the spontaneous breaking of a discrete R symmetry. Those domain walls eventually anni…
