超对称混合充气参数及预热过程

Parameters of SUSY-Hybrid Inflation and the Process of Preheating

Arindam Mazumdar

摘要:

超对称混合暴胀模型的预热过程一般用参数共振和快子预热两种不同的方法来分析。在一个共同的框架下,我们研究了均匀暴胀子场和非均匀瀑布场的衰减和增长过程。我们发现,在超对称混合F项暴胀中,这两个过程并不是参数无关的,而是一个过程比另一个过程更可取,这取决于瀑布场的参数和傅立叶模的值.暴胀势的参数是由观测到的CMB数据约束的,这些约束有助于我们确定负责这个模型的预热过程。

英文摘要:

Process of preheating for supersymmetric hybrid model of inflation is generally analyzed in two different ways known as parametric resonance and tachyonic preheating. In a common frame-work, we study both the processes from the decay or growth of homogeneous inflaton field and inhomogeneous waterfall field. We find that these two processes in SUSY hybrid F-term inflation are not parameter independent; rather one process will be more preferable than the other depending on the values of parameters and Fourier mode of the waterfall field. Parameters of the inflationary potential are constrained from the observed CMB data and these constrains help us to identify the process of preheating responsible for this model.
