标题： Softly Broken N=2 QCD with Massive Quark Hypermultiplets, II

摘要： 我们分析了具有质量夸克超多重态的N=2、SU(2) QCD的真空结构，当超对称性通过标量和质量 spurions 被软破缺到N=0时。 我们以椭圆函数的形式给出了有效势低能耦合的一般表达式，以便完全数值控制该模型。 我们详细研究了对于不同的裸夸克质量和超对称破缺参数下，具有Nf = 1、2味的理论可能的相，并发现了一系列一阶相变。 考虑了Nf = 2理论的手征对称破缺模式，我们得到了这个模型的π介子拉格朗日量，直到二阶导数。 手征对称破缺的磁单极描述中，精确表达了π介子的质量和π介子衰变常数。 显示英文摘要

摘要： We analyze the vacuum structure of N=2, SU(2) QCD with massive quark hypermultiplets, once supersymmetry is softly broken down to N=0 with dilaton and mass spurions. We give general expressions for the low energy couplings of the effective potential in terms of elliptic functions to have a complete numerical control of the model. We study in detail the possible phases of the theories with Nf = 1, 2 flavors for different values of the bare quark masses and the supersymmetry breaking parameters and we find a rich structure of first order phase transitions. The chiral symmetry breaking pattern of the Nf = 2 theory is considered, and we obtain the pion Lagrangian for this model up to two derivatives. Exact expressions are given for the pion masses and the pion decay constant in terms of the magnetic monopole description of chiral symmetry breaking.
