Simple inflationary models in Gauss-Bonnet brane-world cosmology
Nobuchika Okada, Satomi Okada
In light of the recent Planck 2015 results for the measurement of the CMB anisotropy, we study simple inflationary models in the context of the Gauss-Bonnet brane-world cosmology.…
Off-Shell Supersymmetry
Chiu Man Ho, Nobuchika Okada
Supersymmetry does not dictate the way we should quantize the fields in the supermultiplets, and so we have the freedom to quantize the Standard Model (SM) particles and their supe…
Galactic Center gamma-ray excess from two-Higgs-doublet-portal dark matter
Nobuchika Okada, Osamu Seto
We consider a simple extension of the type-II two-Higgs-doublet model by introducing a real scalar as a candidate for dark matter in the present Universe. The main annihilation mod…
Simple brane-world inflationary models in light of BICEP2
Nobuchika Okada, Satomi Okada
Motivated by the recent CMB -mode observation announced by the BICEP2 collaboration, we study simple inflationary models in the Randall-Sundrum brane-world cosmology. Brane-worl…
Towards LHC Physics with Non-local Standard Model
Tirthabir Biswas, Nobuchika Okada
We take a few steps towards constructing a string-inspired nonlocal extension of the Standard Model. We start by illustrating how quantum loop calculations can be performed in nonl…
Direct Bounds on Electroweak Scale Pseudo-Dirac Neutrinos from TeV LHC Data
Arindam Das, P. S. Bhupal Dev, Nobuchika Okada
Seesaw models with a small lepton number breaking can naturally accommodate electroweak-scale pseudo-Dirac neutrinos with a sizable mixing with the active neutrinos, while satisfyi…
