在暴胀膜世界情形中的地球质量谱

Glueballs Mass Spectrum in an Inflationary Braneworld Scenario

L. Barosi, F. A. Brito, H. S. Jesuino, A. R. Queiroz

摘要:

本文讨论了四维宇宙学常数变形的AdS空间边界上的全息对偶场论中的胶球质量问题。这些胶球与该空间上体场的标量和张量涨落有关。在欧几里德AdS 4的情况下,允许的质量是离散的,并与不同的暴胀子质量的3-膜与几个国家的通货膨胀。然后,我们得到的e-折叠数的胶球质量。最后一部分主要讨论了洛伦兹dS 4情形下对偶场论中的QCD状态方程。

英文摘要:

We address the issue of glueball masses in a holographic dual field theory on the boundary of an AdS space deformed by a four-dimensional cosmological constant. These glueballs are related to scalar and tensorial fluctuations of the bulk fields on this space. In the Euclidean AdS4 case the allowed masses are discretized and are related to distinct inflaton masses on a 3-brane with several states of inflation. We then obtain the e-folds number in terms of the glueball masses. In the last part we focus on the Lorentzian dS4 case to focus on the QCD equation of state in dual field theory.
