在直接规范介导情况下产生首阶Gaugino质量的可能性

On the possibility of generating leading order gaugino masses in direct gauge mediation scenario

Tirtha Sankar Ray

摘要:

在直接/半直接规范介导的超对称性破缺模型中,产生首阶的高吉诺质量通常是困难的。Komargodski-Shih定理已经建立了超对称破缺真空的局部稳定性意味着在一般可重整化的O 'Raifeartaigh模型中首阶Gaugino质量消失。我们放松了重整化条件,并探讨了在Kahler势和超势中使用高维算子来回避KS不可行定理的可能性。我们证明了在超域中多项式的高维项不足以回避KS定理。我们缩小了可能的非多项式修正类,可以诱导未抑制的高根质量在全球超对称破缺真空。我们发现,这些模型是诱人的接近强耦合超对称性破缺计划获得的理论。

英文摘要:

Generating gaugino masses at the leading order has typically been difficult in direct/semi-direct gauge mediated supersymmetry breaking models. The Komargodski-Shih theorem has established that local stability of the supersymmetry breaking vacuum implies a vanishing leading order gaugino mass in generic renormalizable O'Raifeartaigh models. We relax the condition of renormalizability and investigate the possibility to evade the KS no-go theorem using higher dimensional operators in the Kahler potential and the superpotential. We demonstrate that higher dimensional terms which are polynomial in superfields are not adequate to evade the KS theorem. We narrow down on the possible class of non-polynomial corrections that can induce unsuppressed gaugino mass in a global supersymmetry breaking vacuum. We find that these models are tantalizingly close to the theories obtained from strongly coupled supersymmetry breaking schemes.
