Slow roll inflation and BB mode angular power spectrum of CMB
N. Malsawmtluangi, P. K. Suresh
TL;DR
This paper calculates the BB-mode angular power spectrum of the CMB considering primordial gravitational waves in a squeezed vacuum state across various inflationary models, comparing results with observational data to constrain inflation models.
Contribution
It introduces the analysis of the BB-mode spectrum using a squeezed vacuum state for primordial gravitational waves across multiple inflationary models.
Findings
Results are consistent with observational data from BICEP2/Keck and Planck.
Certain inflationary models are constrained or favored based on the spectrum analysis.
The approach provides a new way to test inflationary theories against CMB polarization data.
Abstract
The BB-mode angular correlation power spectrum of CMB is obtained by considering the primordial gravitational waves in the squeezed vacuum state for various inflationary models and results are compared with the joint analysis of the BICEP2/Keck Array and Planck 353 GHz data. The present results may constrain several models of inflation.
