超重力下亚稳态SUSY破裂模型

Meta-stable SUSY Breaking Model in Supergravity

Naoyuki Haba

摘要:

在超引力框架下分析了Intriligator,Seiberg和Shih提出的超对称破缺模型.这是一个简单而自然的设置,既不需要额外的超势相互作用,也不需要额外的规范对称性。在SUGRA体系中,U(1)R对称性被超势中的常数项显式破缺,赝模场通过消失的宇宙学常数条件自然地取非零真空期望值.斯费米子往往比高吉诺重,一旦斯费米子和高吉诺的质量之比固定,强耦合的尺度就确定了。

英文摘要:

We analyze a supersymmetry (SUSY) breaking model proposed by Intriligator, Seiberg and Shih in a supergravity (SUGRA) framework. This is a simple and natural setup which demands neither extra superpotential interactions nor an additional gauge symmetry. In the SUGRA setup, the U(1)R symmetry is explicitly broken by the constant term in the superpotential, and pseudo-moduli field naturally takes non-zero vacuum expectation value through a vanishing cosmological constant condition. Sfermions tend to be heavier than gauginos, and the strong-coupling scale is determined once a ratio of sfermion to gaugino masses is fixed.
