Top Spin Correlations in Theories with Large Extra-Dimensions at the Large Hadron Collider
Masato Arai, Nobuchika Okada, Karel Smolek +1
In theories with large extra dimensions, we study the top spin correlations at the Large Hadron Collider. The s-channel process mediated by graviton Kaluza-Klein modes contributes…
Domain Walls with Massive Hypermultiplets
Masato Arai, Muneto Nitta, Norisuke Sakai
Massive hypermultiplets admit degenerate discrete vacua only if they form nonlinear sigma models or have gauge interaction. We discuss BPS domain walls in these theories. This talk…
BPS Wall Solutions in Five Dimensional Supergravity
Masato Arai, Shigeo Fujita, Masashi Naganuma +1
We find an exact solution of BPS wall in five-dimensional supergravity using a gravitational deformation of the massive Eguchi-Hanson nonlinear sigma model. The warp factor decreas…
Massive Nonlinear Sigma Models and BPS Domain Walls in Harmonic Superspace
Masato Arai, Evgeny Ivanov, Jiri Niederle
Four-dimensional massive N=2 nonlinear sigma models and BPS wall solutions are studied in the off-shell harmonic superspace approach in which N=2 supersymmetry is manifest. The gen…
Massive Hyper-Kahler Sigma Models and BPS Domain Walls
Masato Arai, Muneto Nitta, Norisuke Sakai
With the non-Abelian Hyper-Kahler quotient by U(M) and SU(M) gauge groups, we give the massive Hyper-Kahler sigma models that are not toric in the N=1 superfield formalism. The U(M…
BPS Domain Walls in Massive Hyper-Kahler Sigma Models
Masato Arai, Muneto Nitta, Norisuke Sakai
We discuss hypermultiplets admitting degenerate discrete vacua and BPS domain walls interpolating them. This talk is based on the original papers, hep-th/0307274, hep-th/0211103 an…
