Shaft Inflation

摘要:

引入并研究了一类新的通货膨胀模型。该模型的特点是由一个标量的潜力,远离原点,近似于一个通货膨胀的高原,而接近原点成为单项,在混乱的通货膨胀。该模型得到的背景下,全球超对称性开始的超势,从一个广义单项式的O'Raifearteagh形式的小到大的值的暴胀子场分别插值。结果表明,所获得的观测量,如标量谱指数和张量标量比,是在最新的观测结果非常一致。一些讨论的初始条件和永恒的通货膨胀。

英文摘要:

A new family of inflation models is introduced and studied. The models are characterised by a scalar potential which, far from the origin, approximates an inflationary plateau, while near the origin becomes monomial, as in chaotic inflation. The models are obtained in the context of global supersymmetry starting with a superpotential, which interpolates from a generalised monomial to an O'Raifearteagh form for small to large values of the inflaton field respectively. It is demonstrated that the observables obtained, such as the scalar spectral index and the tensor to scalar ratio, are in excellent agreement with the latest observations. Some discussion of initial conditions and eternal inflation is included.
