论文摘要
在本文中，我们考虑了远程平行性对原始黑洞（PBH）产生的可能影响以及重力波（GWS）。我们研究了慢速滚动，电子折叠数和触电参数之间的关系。我们表明，在电触电参数$δ= 3 $的情况下，e-folds数字达到$ 50 $和60美元的$ 50 $和60美元的一致性，与$（r，n_ {s}）$的轮廓图一致，普朗克数据以$1σ$和$2σ$ c.l的方式获得了$1σ$和2σ$ c.l的平面。生产PBH。我们发现，对于在某些狭窄的参数共振下，可以满足PBH过量生产的特定值。此外，要解释通过观察结果预期的GWS，预热的持续时间应以较小或等于$ 2 $的值来限制。该界限与张量比比率的值和受Planck数据约束的光谱指数一致。
In this paper, we consider the possible effect of the teleparallel gravity on the production of the primordial black holes (PBH) and on the gravitational waves (GWs). We investigate the relationship between the slow roll, the e-folds number and the teleparallel parameters. We show that in the case of the teleparallel parameter $δ=3$, the e-folds number reaches the values $50$ and $60$ in consistency with the contour plot of the $(r,n_{s})$ plane obtained by Planck data at $1σ$ and $2σ$ C.L.. Furthermore, we use the fraction of the energy density and the variance of the density perturbations approach to study the abundance of the production PBH. We find that the PBH overproduction can be satisfied for specific values of parameters of the non-adiabatic curvature power spectrum at some narrow parametric resonance. Moreover, to explain the GWs expected by observations, the duration of preheating should be bounded by values less or equal to $2$. This bound is in agreement with values of the tensor-to-scalar ratio and the spectral index constrained by Planck data.
