Inclusive $\eta'$ production in B decays and the Enhancement due to charged technipions

TL;DR

This paper estimates how charged technipions can significantly enhance the inclusive decay rate of B mesons to X_s eta prime, potentially explaining experimental observations.

Contribution

It introduces a new physics contribution from charged technipions to B decay processes, quantifying their impact on the branching ratio.

Findings

Technipions can increase the branching ratio to about 7x10^{-4}.

The effect is significant when considering QCD gluon anomaly.

Results help interpret CLEO experimental data.

Abstract

The new contributions to the charmless B decay $B \to X_{s}\eta^{\prime}$ from the unit-charged technipions $P^{\pm}$ and $P^{\pm}_{8}$ are estimated. The technipions can provide a large enhancement to the inclusive branching ratio: $Br(B \to X_{s}\eta^{\prime}) \sim 7\times 10^{-4}$ for $m_{p1}=100GeV$ and $m_{p8}=250 \sim 350 GeV$ when the effect of QCD gluon anomaly is also taken into account. The new physics effect is essential to interpret the CLEO data.
