反反应弯曲时空中的费米子局域化

Fermion localization in a backreacted warped spacetime

Tanmoy Paul, Soumitra SenGupta

摘要:

我们考虑了在体中存在质量标量场的5维AdS弯曲时空。即使考虑稳定场的反作用,标量场势仍满足模稳定的要求。在这样的情况下,我们探讨的作用,本地化的散装费米子,这反过来又决定了有效的放射性费米子耦合膜上的反反应。结果表明,随着标量场反作用的增加,零阶Kaluza-Klein(KK)费米子的两个手征模都局域在TeV膜附近.我们还表明,大量的KK费米子的档案移向普朗克膜的反反应参数的增加。

英文摘要:

We consider a five dimensional AdS warped spacetime in presence of a massive scalar field in the bulk. The scalar field potential fulfills the requirement of modulus stabilization even when the effect of backreaction of the stabilizing field is taken into account. In such a scenario, we explore the role of backreaction on the localization of bulk fermions which in turn determines the effective radion-fermion coupling on the brane. Our result reveals that both the chiral modes of the zeroth Kaluza-Klein (KK) fermions get localized near TeV brane as the backreaction of the scalar field increases. We also show that the profile of massive KK fermions shifts towards the Planck brane with increasing backreaction parameter.
