TL;DR
This paper investigates the production and detection of string-derived $Z'$ bosons at the LHC, analyzing how kinetic mixing affects observable distributions to distinguish these models.
Contribution
It provides a detailed analysis of $Z'$ signatures in heterotic string models, including the impact of kinetic mixing on LHC observables at NNLO QCD accuracy.
Findings
Kinetic mixing significantly influences forward-backward asymmetry.
Differential distributions can help distinguish string-derived $Z'$ models.
NNLO QCD calculations improve the precision of $Z'$ phenomenology.
Abstract
We consider s in heterotic string derived models and study resonant production at the TeV scale at the Large Hadron Collider (LHC). We use various kinematic differential distributions for the Drell-Yan process at NNLO in QCD to explore the parameter space of such models and investigate couplings. In particular, we study the impact of - kinetic-mixing interactions on forward-backward asymmetry () and other distributions at the LHC.
