通货膨胀与统一

Inflation and Unification

Qaisar Shafi, V. Nefer Senoguz

摘要:

两个不同类别的现实通货膨胀模型符合目前的意见进行审查。第一个例子依赖于Coleman-Weinberg势,并且很容易在自发破缺的全局对称性(例如,全局U(1)_B-L)的框架内实现。根据参数,新的或大的场膨胀是可能的。第二个例子利用了超对称性,这使得在局域规范理论中实现暴胀更容易。讨论了一个基于自发破缺的局部U(1)B-L的例子。在这两种情况下,轻子生成都是自然实现的。

英文摘要:

Two distinct classes of realistic inflationary models consistent with present observations are reviewed. The first example relies on the Coleman-Weinberg potential and is readily realized within the framework of spontaneously broken global symmetries (for instance, global U(1)_B-L). Depending on the parameters either new or large field inflation is possible. The second example exploits supersymmetry which makes implementation of inflation within local gauge theories much more accessible. An example based on spontaneously broken local U(1)_B-L is discussed. Leptogenesis is naturally realized in both cases.
