TL;DR

This paper investigates how the forward-backward asymmetries in specific B-meson decays are affected by the Standard Model and Two Higgs Doublet Model, highlighting their potential to reveal new physics in future experiments.

Contribution

It provides a comparative analysis of polarized and unpolarized asymmetries in B-meson decays within SM and 2HDM, including event number estimates for experimental detection.

Findings

Asymmetries differ significantly between models.

Minimum event numbers for detection are estimated.

Asymmetry studies can help identify new physics.

Abstract

In this paper we shall focus on the effects of concrete models such as SM and Model III of 2HDM on the polarized and unpolarized forward-backward asymmetries of $\overline{B}\rightarrow \overline{K}_0^{*}(1430) \ell^+\ell^-$ and $\overline{B}\rightarrow \overline{K} \ell^+\ell^-$ decays. The obtained results of these decay modes are compared to each other. Also, we obtain the minimum required number of events for detecting each asymmetry and compare them with the number of produced $B\bar{B}$ pairs at the LHC or supposed to be produced at the Super-LHC. At the end, we conclude that the study of these asymmetries for $\overline{B}\rightarrow \overline{K}_0^*(1430) \ell^+\ell^-$ and $\overline{B}\rightarrow \overline{K} \ell^+\ell^-$ processes are very effective tools for establishing new physics in the future B-physics experiments.
