Dynamics of Rolling Massive Scalar Field Cosmology

TL;DR

This paper investigates how a rolling massive scalar field influences inflationary cosmology within braneworld models, highlighting the need for warp factor tuning and demonstrating attractor behavior in different scenarios.

Contribution

It provides new insights into the inflationary dynamics of massive scalar fields in braneworld cosmology, including conditions for observational consistency and attractor properties.

Findings

Warp factor must be less than 10^{-3} for observational fit

Demonstrates inflationary attractor behavior in both standard and braneworld scenarios

Analyzes scalar field dynamics with warped metric in cosmology

Abstract

We study the inflationary consequences of the rolling massive scalar field in the braneworld scenario with a warped metric. We find that in order to fit observational constraints the warp factor must be tuned to be $< 10^{-3}$. We also demonstrate the inflationary attractor behavior of the massive scalar field dynamics both in the standard FRW case as well as in braneworld scenario.
