A hybrid 4$^{\textrm{th}}$ generation: Technicolor with top-seesaw

TL;DR

This paper proposes a hybrid model combining technicolor and top quark condensation, predicting a new fourth generation of leptons and quarks, and analyzes its viability against experimental constraints and LHC data.

Contribution

It introduces a novel fourth generation within a technicolor-top seesaw framework using Minimal Walking Technicolor, and evaluates its experimental viability.

Findings

Model is consistent with current precision measurements.

Predicted fourth generation leptons and quarks are viable.

Contrasts with LHC data and discusses future detection prospects.

Abstract

We consider a model combining technicolor with the top quark condensation. As a concrete model for Technicolor we use the Minimal Walking Technicolor, and this will result in the appearance of a novel fourth generation whose leptons constitute a usual weak doublet while the QCD quarks are vectorlike singlets under the weak interactions. We carry out an analysis of the mass spectra and precision measurement constraints, and find the model viable. We contrast the model with present LHC data and discuss the future prospects.
