Top quark forward-backward asymmetry and charge asymmetry in the left-right twin Higgs model
Top quark forward-backward asymmetry and charge asymmetry in the left-right twin Higgs model
In order to explain the Tevatron anomaly of the top quark forward-backward asymmetry ${A}_{\mathrm{FB}}^{t}$ in the left-right twin Higgs model, we choose to give up the lightest neutral particle of $\stackrel{^}{h}$ field as a stable dark matter candidate. Then a new Yukawa interaction for $\stackrel{^}{h}$ is allowed, which can be …
