“…In this case the NS5 branes have to pass over each other and some strong coupling phenomena have to be considered. Similar results were obtained in [9,10,11] where the moduli space of the supersymmetric gauge theories is geometrically encoded in the brane setup.…”

“…Far from the origin of the (v, w) plane which is the location of D4 branes, the location of the NS5 brane in the s plane can be described by s(NS5) = −2R(N f − N c − 1) ln v while the NS'5 brane in the s plane by s(NS ′ 5) = −2R(N c + 1) ln w. We discuss about the R-symmetries of the rotated configuration. After rotation, SU(2) 7,8,9 is broken to U(1) 8,9 . In order this to be true, because of the connection between v and w in (4.2), µ has to have charges under U(1) 4,5 × U(1) 8,9 .…”

We analyze M theory fivebrane in order to study the moduli space of vacua of N = 1 supersymmetric Sp(N c ) gauge theories with N f flavors in four dimensions. We show how the N = 2 Higgs branch can be encoded in M theory by studying the orientifold which plays a crucial role in our work. When all the quark masses are the same, the surface of the M theory spacetime representing a nontrivial S 1 bundle over R 3 develops A N f −1 type singularities at two points where D6 branes are located. Furthermore, by turning off the masses, two singular points on the surface collide and produce A 2N f −1 type singularity. The sum of the multiplicities of rational curves on the resolved surface gives the dimension of N = 2 Higgs branch which agrees with the counting from the brane configuration picture of type IIA string theory. By rotating M theory fivebranes we get the strongly coupled dynamics of N = 1 theory and describe the vacuum expectation values of the meson field parameterizing Higgs branch which are in complete agreement with the field theory results. Finally, we take the limit where the mass of adjoint chiral multiplet goes to infinity and compare with field theory results. For massive case, we comment on some relations with recent work which deals with N = 1 duality in the context of M theory.

“…While brane dynamics provides information about field theory, one also learns about properties of brane configurations from field theory knowledge. One considers branes either in the context of perturbative string theory [1][2][3][4][5][6][7][8][9][10][11][12][13][14] or embedded in M-theory or F-theory .…”

Gauge theories with tensors from branes and orientifolds

We present brane constructions in Type IIA string theory for N = 1 supersymmetric SO and Sp gauge theories with tensor representations using an orientifold 6-plane. One limit of these set-ups corresponds to N = 2 theories previously constructed by Landsteiner and Lopez, while a different limit yields N = 1 SO or Sp theories with a massless tensor and no superpotential. For the Sp-type orientifold projection comparison with the field theory moduli space leads us to postulate two new rules governing the stability of configurations of D-branes intersecting the orientifold. Lifting one of our configurations to M-theory by finding the corresponding curves, we re-derive the N = 1 dualities for SO and Sp groups using semi-infinite D4 branes.

Coupling fundamental quarks to QCD in the dual string representation corresponds to adding the open string sector. Flavors therefore should be represented by space-time filling D-branes in the dual 5d closed string background. This requires several interesting properties of D-branes in AdS. D-branes have to be able to end in thin air in order to account for massive quarks, which only live in the UV region. They must come in distinct sets, representing the chiral global symmetry, with a bifundamental field playing the role of the chiral condensate. We show that these expectations are born out in several supersymmetric examples. To analyze most of these properties it is not necessary to go beyond the probe limit in which one neglects the backreaction of the flavor D-branes.
