Black-Body Anomaly: Analysis of Temperature Offsets

TL;DR

This paper predicts temperature offsets in black-body spectra due to a hypothesized photon propagation governed by a broken SU(2) gauge symmetry, suggesting potential explanations for CMB anomalies and emphasizing the need for experimental verification.

Contribution

It introduces a novel theoretical framework linking photon propagation to a broken SU(2) gauge symmetry, predicting measurable temperature offsets in black-body spectra.

Findings

Predicted temperature offsets are within experimental error margins of FIRAS data.

Results suggest a possible dynamical component in the CMB dipole.

Indicates the need for dedicated low-temperature black-body experiments.

Abstract

Based on the postulate that photon propagation is governed by a dynamically broken SU(2) gauge symmetry (scale $\sim 10^{-4} $eV) we make predictions for temperature offsets due to a low-temperature (a few times the present CMB temperature) spectral anomaly at low frequencies. Temperature offsets are extracted from least-square fits of the anomalous black-body spectra to their conventional counterparts. We discuss statistical errors, compare our results with those obtained from calibration data of the FIRAS instrument, and point out that our predicted offsets are screened by experimental errors given the frequency range used by FIRAS to perform their spectral fits. We also make contact with the WMAP observation by blueshifting their frequency bands. Although our results hint towards a strong dynamical component in the CMB dipole and an explanation of low-$l$ suppression it is important in view of its particle-physics implications that the above postulate be verified/falsified by an independent low-temperature black-body precision experiment.
