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…
Revisiting T2KK and T2KO physics potential and - beam ratio
Kaoru Hagiwara, Pyungwon Ko, Naotoshi Okamura +1
We revisit the sensitivity study of the Tokai-to-Kamioka-and-Korea (T2KK) and Tokai-to-Kamioka-and-Oki (T2KO) proposals where a water Cerenkov detector with the 100 kton fiducial v…
ATLAS on-Z Excess Through Vector-Like Quarks
Motoi Endo, Yoshitaro Takaesu
We investigate the possibility that the excess observed in the leptonic-jets $+\slashed{E}_T$ ATLAS SUSY search is due to pair productions of a vector-like quark decaying…
Di-Higgs Decay of Stoponium at Future Photon-Photon Collider
Hayato Ito, Takeo Moroi, Yoshitaro Takaesu
We study the detectability of the stoponium in the di-Higgs decay mode at the photon-photon collider option of the International Linear Collider (ILC), whose center-of-mas…
Studying 750 GeV Di-photon Resonance at Photon-Photon Collider
Hayato Ito, Takeo Moroi, Yoshitaro Takaesu
Motivated by the recent LHC discovery of the di-photon excess at the invariant mass of ~ 750 GeV, we study the prospect of investigating the scalar resonance at a future photon-pho…
Revisiting Big-Bang Nucleosynthesis Constraints on Dark-Matter Annihilation
Masahiro Kawasaki, Kazunori Kohri, Takeo Moroi +1
We study the effects of dark-matter annihilation during the epoch of big-bang nucleosynthesis on the primordial abundances of light elements. We improve the calculation of the ligh…
