论文摘要

d $ p $ branes获得了有效的非线性描述,其玻体部件与出生的污染行动有关。这种非线性已被证明是部分$ {\ cal n} = 2 \ to {\ cal n} = 1 $ supersymmetry brewing的结果,起源于麸皮的孤子性质。在这项工作中,我们专注于对D2-branes的有效描述。使用对动作的金石多重解释和nilpotent $ {\ cal n} = 2 $超级场的方法,我们构造了3D,$ {\ cal n} = 1 $ superspace有效的动作,这使第一个超对称性表现出来,并意识到第二个,并意识到第二个,自发性地破碎,suplesymmetry norlinalealearly。我们表明,3D出发的污染作用有两个这样的超对称性扩展,它们分别对应于3D Maxwell-Goldstone多重组的动力学和张量 - Goldstone多重组的3D投影。此外,我们证明了这些结果是通过在$ {\ cal n} = 2上应用约束的超级场方法来得出的,d = 3 $ vector和手性多重组在非平凡的真空周围扩展后。我们发现,这两个描述是通过二元转换相关的,这导致无量纲参数的反转。对于这两个描述,我们都会得出3D超生式攻击动作的显式骨气和费米子部分。最后,考虑特征性的chern-simons样子,量规术语,质量术语的特征性chern-simons样子的变形。

D$p$-branes acquire effective nonlinear descriptions whose bosonic part is related to the Born-Infeld action. This nonlinearity has been proven to be a consequence of the partial ${\cal N}=2\to{\cal N}=1$ supersymmetry breaking, originating from the solitonic nature of the branes. In this work, we focus on the effective descriptions of D2-branes. Using the Goldstone multiplet interpretation of the action and the method of nilpotent ${\cal N}=2$ superfields, we construct the 3D, ${\cal N}=1$ superspace effective action which makes the first supersymmetry manifest and realizes the second, spontaneously broken, supersymmetry nonlinearly. We show that there are two such supersymmetric extensions of the 3D Born-Infeld action which correspond to the dynamics of the 3D Maxwell-Goldstone multiplet and the 3D projection of the Tensor-Goldstone multiplet respectively. Moreover, we demonstrate that these results are derived by applying the constrained superfield approach on the ${\cal N}=2, D=3$ vector and chiral multiplets after expanding them around a nontrivial vacuum. We find that these two descriptions are related by a duality transformation which results in the inversion of a dimensionless parameter. For both descriptions we derive the explicit bosonic and fermionic parts of the 3D super Born-Infeld action. Finally, consider the deformation of the Maxwell-Goldstone superspace action by the characteristic Chern-Simons-like, gauge invariant, mass term.
