Infinite Lorentz boost along the M-theory circle and non-asymptotically flat solutions in supergravities
Seungjoon Hyun, Youngjai Kiem, Hyeonjoon Shin
Certain non-asymptotically flat but supersymmetric classical solution of the type IIA supergravity can be interpreted as the infinitely-boosted version of the D-particle solution a…
Superpotentials of N=1 Supersymmetric Gauge Theories from M-theory
Soonkeon Nam, Kyungho Oh, Sang-Jin Sin
We consider brane configurations in M-theory describing N=1 supersymmetric gauge theories and using the parametric representation of the brane configurations, we calculate the supe…
Composite Skyrme Model with Vector Mesons
Kwanghoon Hahm, KyoungHo Han, H. J. Shin
We study the composite Skyrme model, proposed by Cheung and Gürsey, introducing vector mesons in a chiral Lagrangian. We calculate the static properties of baryons and compare with…
Grassmann manifold Bosonization of QCD in Two Dimensions
KyoungHo Han, H. J. Shin
Two dimensional QCD is bosonized to be an integrably deformed Wess-Zumino-Witten model under proper limit. Fermions are identified having indices of the Grassmann manifold. Conditi…
Geometry, D-Branes and N=1 Duality in Four Dimensions I
Changhyun Ahn, Kyungho Oh
We consider N=1 dualities in four dimensional supersymmetric gauge theories as a geometrical realization of wrapping D 6-branes around 3-cycles of Calabi-Yau threefolds in type IIA…
Instanton-induced Effective Vertex in the Seiberg-Witten Theory with Matter
ByungKoo Lee, Soonkeon Nam
The instanton-induced effective vertex is derived for N=2 supersymmetric QCD (SQCD) with arbitrary mass matter hypermultiplets for the case of SU(2). The leading term of the low en…
