“…This is recognizable as a spinor analogue of the unbroken supercharge within the S 3 model. If we now drop the translational zero modes, and restrict Q α to the reduced moduli space, with x i = {ξ 0 , φ 0 }, then we discover that there is a second unbroken spinor supercharge, existing by virtue of the complex structure J associated with M = S 2 , introduced earlier in (16). We can then form a complex spinor charge…”

“…The corresponding central charge is present in the superalgebra [9] and such solitons are 1/2-BPS saturated. In previous work [10], we studied the BPS wall spectrum in this theory, following earlier work on BPS walls in other variants of N= 1 SQCD [9,[11][12][13][14][15][16][17]. The vacuum structure is illustrated in the plane of the superpotential in Fig.…”

We study the worldvolume dynamics of BPS domain walls in N= 1 SQCD with N f = N flavors, and exhibit an enhancement of supersymmetry for the reduced moduli space associated with broken flavor symmetries. We provide an explicit construction of the worldvolume superalgebra which corresponds to an N = 2 Kähler sigma model in 2+1D deformed by a potential, given by the norm squared of a U(1) Killing vector, resulting from the flavor symmetries broken by unequal quark masses. This framework leads to a worldvolume description of novel two-wall junction configurations, which are 1/4-BPS objects, but nonetheless preserve two supercharges when viewed as kinks on the wall worldvolume.

“…Consequently, there are no massless excitations on the wall worldvolume, other than the translational modes. Numerical analysis in [15][16][17]19] , then additional solutions will arise in pairs by permutation of the fields. Perturbative analysis indicates that there are at most four trajectories emanating from each vacuum, and an analysis along the lines of [38] demonstrates that only two of these interpolate to the second vacuum providing true wall configurations.…”

We study the multiplicity of BPS domain walls in N = 1 super Yang-Mills theory, by passing to a weakly coupled Higgs phase through the addition of fundamental matter. The number of domain walls connecting two specified vacuum states is then determined via the Witten index of the induced worldvolume theory, which is invariant under the deformation to the Higgs phase. The worldvolume theory is a sigma model with a Grassmanian target space which arises as the coset associated with the global symmetries broken by the wall solution. Imposing a suitable infrared regulator, the result is found to agree with recent work of Acharya and Vafa in which the walls were realized as wrapped D4-branes in IIA string theory.
