5th Force and Quark Mixing

TL;DR

This paper tests a novel 5th fundamental force theory predicting quark mixing and CP violation, finding it aligns well with recent experimental data, unlike the traditional CKM theory.

Contribution

It introduces a 5th force-based model that predicts quark mixing and CP violation, providing a better fit to experimental data than the CKM theory.

Findings

The 5th force model accurately predicts quark mixing parameters.

The CKM theory shows poor agreement with recent data.

The 5th force theory withstands tests in both accuracy and precision.

Abstract

In a recent article, this author proposed a program for physics beyond the Standard Model, solely based on modifying the twin pillars of fundamental physics by replacing Lorentz structure with Euclidean Jordan algebra while keeping quantum theory. This program predicts not only quarks and leptons but also a short-range 5th fundamental force accompanying gravity. This 5th force predicts quark mixing and the related CP violation, which in fact was a phenomena observed in labs about fifty years ago. Thus, there are two conflicting theories as of now, the one based on the 5th force which {\em predicts} this phenomena and the established Cabibbo-Kobayashi-Maskawa (CKM) theory which was invented to {\em explain} this phenomena. In this article a test of these two theories against the recent experimental data is presented. It is found in this test that the CKM theory fares poorly, whereas the one based on the 5th force withstands the test well, in both accuracy and precision. For example, for the CKM matrix entry $V_{cd}$, we have $$|V_{cb}^{\tiny \mbox{experiment}}|=0.0409 \pm 0.0011, \quad |V_{cb}^{\tiny \mbox{CKM}}|= 2.37\pm 1.82,\quad |V_{cb}^{\tiny \mbox{5th force}}|=0.0408 \pm 0.0028. $$
