模的重定义与模的稳定化

Moduli Redefinitions and Moduli Stabilisation

Joseph P. Conlon, Francisco G. Pedro

摘要:

字段重定义发生在一个循环级别的字符串压缩中。我们回顾了为什么会发生这种重新定义的争论,并研究了它们对大体积情况下模量稳定和超对称破缺的影响。对于小模数,虽然这种重新定义的影响可能比Kähler势和标量势中的$α'$修正更大,但它们不会改变标量势的结构。对于大模数的不太好的动机的情况下,重新定义可以支配标量势中的所有其他项。我们还研究了重定义对超对称破缺和软项结构的影响。

英文摘要:

Field redefinitions occur in string compactifications at the one loop level. We review arguments for why such redefinitions occur and study their effect on moduli stabilisation and supersymmetry breaking in the LARGE volume scenario. For small moduli, although the effect of such redefinitions can be larger than that of the $α'$ corrections in both the Kähler and scalar potentials, they do not alter the structure of the scalar potential. For the less well motivated case of large moduli, the redefinitions can dominate all other terms in the scalar potential. We also study the effect of redefinitions on the structure of supersymmetry breaking and soft terms.
