标题： Higher-derivative supersymmetric effective field theories

摘要： 本文研究了高阶导数超对称有效场论，重点在于从谱中消除鬼场的系统性方法。特别关注辅助场，因为高阶导数项会导致非代数运动方程。通过场重新定义或降阶程序（在分量和超场语言中），我们证明了辅助场在有效场论中仍然是非动力学的，并且在场论方程解出后，它们对标量作用量既产生了导数修正也产生了非导数修正。这些方法被应用于寻找DBI作用量的超对称嵌入，以及用于IIB型弦理论紧化中Kähler模量的高阶导数项的维度约化。 显示英文摘要

摘要： In this paper we study higher-derivative supersymmetric effective field theories focusing on the systematic procedure for the elimination of ghosts from the spectrum. Particular attention is paid to the auxiliary fields, for which the higher-derivative terms induce non-algebraic equations of motion. By employing field redefinitions or the reduction of order procedure (both in component and superfield language) we show that the auxiliary fields remain non-dynamical in the EFT and that on shell they give rise to both derivative and non-derivative corrections to the scalar action. These methods are applied to the search for a SUSY embedding of the DBI action and to the dimensional reduction of HD terms for the K\"ahler moduli in type IIB string compactifications.
