MSSM规范不变单项式的完备极小目录

A complete and minimal catalogue of MSSM gauge invariant monomials

Anders Basboll

摘要:

本文给出了MSSM规范不变单项式的一个完备的极小目录。也就是说,Gherghetta、Kolda和Martin的目录被详细阐述为包括所有单名的世代结构。任何规范不变算子都可以建立为提升到非负整数幂的目录元素的线性组合。去掉任何一个单项式都会使目录失去这个特征。它包含了712个单项式--如果把模型推广到$ν$ MSSM,再加上3代右手中微子。我们注意到,$ν$ MSSM平坦方向都可以被6阶超势提升-相比之下,MSSM需要9阶超势。

英文摘要:

We present a complete and minimal catalogue of MSSM gauge invariant monomials. That is, the catalogue of Gherghetta, Kolda and Martin is elaborated to include generational structure for all monomials. Any gauge invariant operator can be built as a linear combination of elements of the catalogue lifted to nonnegative integer powers. And the removal of any one of the monomials would deprive the catalogue of this feature. It contains 712 monomials - plus 3 generations of righthanded neutrinos if one extends the model to the $ν$MSSM. We note that $ν$MSSM flat directions can all be lifted by the 6th order superpotential - compared to the 9th order needed in MSSM.
