Index for three dimensional superconformal field theories with general R-charge assignments
We derive a general formula of an index for three dimensional $ \mathcal{N} = 2 $ super-conformal field theories with general R-charge assignments to chiral multiplets by using the localization
Primordial Black Hole Scenario for the Gravitational-Wave Event GW150914.
The abundance of PBHs required to explain the suggested lower bound on the event rate roughly coincides with the existing upper limit set by the nondetection of the cosmic microwave background spectral distortion, which implies that the proposed PBH scenario may be tested in the not-too-distant future.
Primordial Black Holes - Perspectives in Gravitational Wave Astronomy -
This is a review article on the primordial black holes (PBHs), with particular focus on the massive ones ($\gtrsim 10^{15}{\rm g}$) which have not evaporated by the present epoch by the Hawking
Current status of space gravitational wave antenna DECIGO and B-DECIGO
The Deci-hertz Interferometer Gravitational Wave Observatory (DECIGO) is a future Japanese space mission with a frequency band of 0.1 Hz to 10 Hz. DECIGO aims at the detection of primordial
Primordial Non-Gaussianity in Multi-Scalar Inflation
We give a concise formula for the non-Gaussianity of the primordial curvature perturbation generated on super-horizon scales in multi-scalar inflation model without assuming slow-roll conditions.
Chern Simons duality with a fundamental boson and fermion
A bstractWe compute the thermal free energy for all renormalizable Chern Simon theories coupled to a single fundamental bosonic and fermionic field in the ’t Hooft large N limit. We use our results
Chern-Simons Theories and Wrapped M-Branes in Their Gravity Duals
We investigate a class of N = 4 quiver Chern-Simons theories and their gravity duals. We define the group of fractional D3-brane charges in a type IIB brane setup with taking account of D3-brane
Primordial statistical anisotropy generated at the end of inflation
We present a new mechanism for generating primordial statistical anisotropy of curvature perturbations. We introduce a vector field which has a non-minimal kinetic term and couples with a waterfall
Primordial Non-Gaussianity in Multi-Scalar Slow-Roll Inflation
We analyze the non-Gaussianity for primordial curvature perturbations generated in multi-scalar slow-roll inflation model including the model with non-separable potential by making use of $\delta N$
Constraints on Earth-mass primordial black holes from OGLE 5-year microlensing events
We constrain the abundance of primordial black holes (PBH) using 2622 microlensing events obtained from 5-years observations of stars in the Galactic bulge by the Optical Gravitational Lensing
