Duality in Non-Supersymmetric MQCD
نویسنده
چکیده
The curves that describe the M-theoretic extension of type IIA string configurations with non-supersymmetric field theories on their surface exhibit a duality map. The map suggests a continued link between a SU(N) gauge theory with F flavours and an SU(F − N) gauge theory with F flavours (the duality of supersymmetric QCD) even when the gaugino mass is taken to infinity. Within the context of the field theory such a duality only continues to make sense if the scalar fields remain light. We discuss the difficulties of decoupling the scalars within this framework.

Metastable Vacua, Geometrical Engineering and MQCD Transitions
We consider the geometrical engineering of the non-supersymmetric metastable vacua of N = 1 super Yang-Mills proposed in [8] and [22]. By T-duality they become N = 1 brane configurations. The identifications between gluino condensation and the geometry sizes for the configurations of [22] are studied by proceeding through the usual MQCD transitions. The geometrical description of the Seiberg du...
متن کاملA Note on (Meta)stable Brane Configurations in MQCD
We examine the M-theory version of SQCD which is known as MQCD. In the IIA limit, this theory appears to have a supersymmetry-breaking brane configuration which corresponds to the meta-stable state of N = 1 SU(Nc) SQCD. However, the behavior at infinity of this non-supersymmetric brane construction differs from that of the supersymmetric ground state of MQCD. We interpret this to mean that it i...
متن کاملComments on Duality in MQCD
We clarify some ambiguous points in a derivation of duality via brane exchange using M-theory language, and propose a “proof” of duality in MQCD. Actually, duality in MQCD is rather trivial and does not need a complicated proof. The problem is how to interpret it in field theory language. We examine BPS states in N = 2 theory and find the particle correspondence under duality. In the process, w...
متن کاملSoftly Broken MQCD and the Theta Angle
We consider a family of non-supersymmetric MQCD five-brane configurations introduced by Witten, and discuss the dependence of the curves on the microscopic theta angle and its relation with CP. We find evidence for a non-trivial spectral flow of the curves (vacua) and for the level-crossing of adjacent curves at a particular value of the theta angle, with spontaneous breaking of CP symmetry, pr...
متن کاملIntersecting 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]
