Intersecting domain walls in MQCD
We argue that MQCD admits intersecting domain walls that are realized as Cayley calibrations of the MQCD M5-brane. We discuss various dual realizations and comment on how branes can realise domain walls in N=1 supersymmetric theories in D=3. 1 E-mail: [email protected] 2 E-mail: [email protected] 3 E-mail: [email protected]
متن کاملDomain Walls in MQCD and Monge-Ampère Equation
We study Witten’s proposal that a domain wall exists in M-theory fivebrane version of QCD (MQCD) and that it can be represented as a supersymmetric three-cycle in G2 holonomy manifold. It is shown that equations defining the U(1) invariant domain wall for SU(2) group can be reduced to the Monge-Ampère equation. A proof of an algebraic formula of Kaplunovsky, Sonnenschein and Yankielowicz is pre...
متن کاملSupersymmetric Intersecting Domain Walls in Massive Hyper-Kähler Sigma Models
The general scalar potential of D-dimensional massive sigma-models with eight supersymmetries is found for D = 3, 4. These sigma models typically admit 1/2 supersymmetric domain wall solutions and we find, for a particular hyperKähler target, exact 1/4 supersymmetric static solutions representing a nontrivial intersection of two domain walls. We also show that the intersecting domain walls can ...
متن کاملOn Superpotential and BPS domain wall in SQCD and MQCD
We examine the decoupling properties of the N=2 SQCD vacua when the adjoint mass term is turned on and then the N=1 limit is taken. The BPS domain wall tension in N=1 MQCD and SQCD is also examined. The correspondence of the MQCD integrals with the superpotential and the gaugino condensate is shown. [email protected]
متن کاملDomain Walls in QCD
QCD was shown to have a nontrivial vacuum structure due to the topology of the θ ≡ θ+2πn parameter. As a result of this nontrivial topology, in the large Nc limit, quasi-stable QCD domain walls appear, characterized by a transition in the singlet η field. We discuss the physics of these QCD domain walls as well as related axion domain walls and we present a new type of axion wall which also con...
