TL;DR

This paper proposes a method to detect new physics beyond the standard model by analyzing photon polarization in radiative B meson decays, applicable in SUSY GUT and left-right symmetric models, with potential for TeV-scale discoveries.

Contribution

It introduces a discriminant analysis technique for photon polarization detection in B decays, comparing its effectiveness with CP asymmetry methods across different new physics models.

Findings

Photon polarization detection can reveal new physics at TeV energy scales.

The method distinguishes between SUSY GUT and left-right symmetric models.

Photon polarization offers a complementary approach to CP asymmetry in new physics searches.

Abstract

We suggest a discriminant analysis of new physics beyond the standard model through a detection of photon polarization in a radiative B meson decay. This analysis is investigated in SUSY SU(5) GUT with right-handed neutrino and left-right symmetric models. New physics search via CP asymmetry in the same process are also evaluated in each model for comparison. We show that new physics can be found via detecting the photon polarization in a parameter space of TeV energy scale.
