Saurabh D. Rindani, Rui Santos, Pankaj Sharma
TL;DR
This paper explores how top-quark polarization and azimuthal asymmetry measurements at the LHC can determine or differentiate the charged Higgs boson mass and models beyond the Standard Model.
Contribution
It introduces a method using top-quark observables to measure the charged Higgs mass and distinguish between different theoretical models.
Findings
Top-quark polarization and azimuthal asymmetry are effective in constraining the charged Higgs mass.
The proposed observables can differentiate between various extensions of the Standard Model.
The study provides a framework for experimental analysis at the LHC.
Abstract
We study the process of single-top production in association with a charged Higgs boson at the LHC and discuss how top-quark polarization and an azimuthal asymmetry of the charged lepton from top decay can be used in some extensions of the Standard Model to determine or constrain the charged Higgs boson mass. We also discuss some scenarios where these variables can be used to distinguish between different models.
