Cosmic Background Radiation Mini-Review

TL;DR

This mini-review summarizes the state of Cosmic Microwave Background (CMB) anisotropy research and its implications for cosmology and particle physics as of 2003, highlighting key data, interpretations, and future prospects.

Contribution

It provides a comprehensive, updated overview of CMB anisotropy results, their interpretation, and implications for cosmological and particle physics models as of 2003.

Findings

Assessment of CMB anisotropy results up to 2003

Implications for cosmological parameters and models

Discussion of future research directions

Abstract

This is a complete re-write of the mini-review for the Review of Particle Physics (a.k.a the Partcicle Data Book), which includes an assessment of the CMB anisotropy results and their interpretation up until the end of 2003. It forms a compact overview of the field at this time. Sections headings are: Introduction; Description of CMB Anisotropies; Cosmological Parameters; Physics of Anisotropies; Current Anisotropy Data; CMB Polarization; Complications; Constraints on Cosmologies; Particle Physics Constraints; Fundamental Lessons; and Future Directions.
