一类新的四维N=1非最小导数耦合超引力

A New Class of Four-Dimensional N=1 Supergravity with Non-minimal Derivative Couplings

Fotis Farakos, Cristiano Germani, Alex Kehagias, Emmanuel N. Saridakis

摘要:

在N=1的四维新极小超引力框架中,我们对标量动力学项与爱因斯坦张量的耦合进行了超对称化。这种耦合虽然引入了曲率与物质的非最小导数相互作用,但它不会引入有害的高阶导数。对于这个建设,我们采用离壳手征和真正的线性多重峰。物理标量被容纳在手征多重态,而曲率驻留在一个线性的。

英文摘要:

In the N=1 four-dimensional new-minimal supergravity framework, we supersymmetrise the coupling of the scalar kinetic term to the Einstein tensor. This coupling, although introduces a non-minimal derivative interaction of curvature to matter, it does not introduce harmful higher-derivatives. For this construction, we employ off-shell chiral and real linear multiplets. Physical scalars are accommodated in the chiral multiplet whereas curvature resides in a linear one.
