Running Standard Model Inflation And Type I Seesaw
Nobuchika Okada, Mansoor Ur Rehman, Qaisar Shafi
Several authors have recently argued that a satisfactory inflationary scenario can be implemented in the Standard Model (SM) by introducing a strong non-minimal coupling of the Hig…
Gauge-Higgs Dark Matter
Naoyuki Haba, Shigeki Matsumoto, Nobuchika Okada +1
When the anti-periodic boundary condition is imposed for a bulk field in extradimensional theories, independently of the background metric, the lightest component in the anti-perio…
The minimal B-L model naturally realized at TeV scale
Satoshi Iso, Nobuchika Okada, Yuta Orikasa
In a previous paper, we have proposed the minimal B-L extended standard model as a phenomenologically viable model that realizes the Coleman-Weinberg-type breaking of the electrowe…
The PAMELA and Fermi signals from long-lived Kaluza-Klein dark matter
Nobuchika Okada, Toshifumi Yamada
We propose a simple extension of the minimal universal extra dimension (UED)model by introducing a small curvature. The model is formulated as a small anti-de Sitter curvature limi…
Type II Seesaw and the PAMELA/ATIC Signals
Ilia Gogoladze, Nobuchika Okada, Qaisar Shafi
We discuss how the cosmic ray signals reported by the PAMELA and ATIC/PPB-BETS experiments may be understood in a Standard Model (SM) framework supplemented by type II seesaw and a…
Effects of unparticle on top spin correlation at the Large Hadron Collider
Masato Arai, Nobuchika Okada, Karel Smolek
We study effects of the scale invariant hidden sector, unparticle, proposed by Georgi, on top spin correlation at the Large Hadron Collider. Assuming no flavor changing interaction…
