Killing Spinor in Linearly Confining Supergravity
Girma Hailu
The killing spinor of a linearly confining supergravity background previously proposed and argued to produce features of pure N=1 SU(N) gauge theory in four dimensions is construct…
Cosmology on Compact and Stable Supergravity Background
Girma Hailu
We propose a cosmological model of D3-brane universe on compact and stable supergravity background of wrapped D7-branes in type IIB string theory previously argued to be dual to pu…
Glueball Masses from Linearly Confining Supergravity
Girma Hailu
Mass spectrum of 0++ glueballs is produced using a dual supergravity theory we proposed for pure N=1 SU(N) gauge theory in four dimensions in the large N limit in the IR. The glueb…
Gravity Dual to Pure N=1 SU(N) Gauge Theory
Girma Hailu
A correspondence between type IIB string theory with N D7-branes on R^{1,3} x C^1/Z_2 x T^2/Z_2 x T^2/Z_2 and pure N=1 SU(N) gauge theory in four dimensions is proposed and argued.…
Linear Confinement of Quarks from Supergravity
Girma Hailu
A supergravity background that produces linear confinement of quarks in four dimensions is presented.
Duality Cascade in Brane Inflation
Rachel Bean, Xingang Chen, Girma Hailu +2
We show that brane inflation is very sensitive to tiny sharp features in extra dimensions, including those in the potential and in the warp factor. This can show up as observationa…
