Inflaton phenomenology via reheating in light of primordial gravitational waves and the latest BICEP/$Keck$ data

Understand

We are in the era of precision cosmology which offers us a unique opportunity to investigate beyond standard model physics.

• Toward this endeavor, inflaton is assumed to be a perfect new physics candidate.
• In this submission, we explore the phenomenological impact of the latest observation of PLANCK and BICEP/$Keck$ data on the physics of inflation.
• We particularly study three different models of inflation, namely $\alpha$-attractor E, T, and the minimal plateau model.
