基于Super Yang-Mills、Orientifold和One Flavor QCD的复合通货膨胀

Composite Inflation from Super Yang-Mills, Orientifold and One-Flavor QCD

P. Channuie, J. J. Joergensen, F. Sannino

摘要:

最近的研究表明,暴胀可以由四维强相互作用理论驱动,这些理论与引力非最小耦合。我们通过考虑由东方场论驱动的复合暴胀来进一步探索这一范式。使用这些理论的优点在于,在大量的颜色,他们具有某些超级杨米尔斯性质。特别地,我们可以将Veneziano-Yankielowicz有效理论的玻色子部分用于暴胀。此外,我们包括1/N以及费米子质量修正的有效拉格朗日水平,使我们能够探索这些修正对通货膨胀慢卷参数的影响。另外,费米子物质按照三色双指数反对称表象变换的定向折叠场论也是QCD。因此这个模型可以解释为一个新的非最小耦合的暴胀QCD理论。对于这里提出的所有模型,复合暴胀的尺度都是$10^{16}$ GeV的量级。暴胀子散射的么正性研究表明,该模型的截止尺度是普朗克尺度。

英文摘要:

Recent investigations have shown that inflation can be driven by four-dimensional strongly interacting theories non-minimally coupled to gravity. We explore this paradigm further by considering composite inflation driven by orientifold field theories. The advantage of using these theories resides in the fact that at large number of colors they feature certain super Yang-Mills properties. In particular we can use for inflation the bosonic part of the Veneziano-Yankielowicz effective theory. Furthermore, we include the 1/N as well as fermion mass corrections at the effective Lagrangian level allowing us to explore the effects of these corrections on the inflationary slow-roll parameters. Additionally the orientifold field theory with fermionic matter transforming according to the two-index antisymmetric representation for three colors is QCD. Therefore this model can be interpreted as a new non-minimally coupled QCD theory of inflation. The scale of composite inflation, for all the models presented here, is of the order of $10^{16}$ GeV. Unitarity studies of the inflaton scattering suggest that the cutoff of the model is at the Planck scale.
