Renormalization in a Lorentz-violating model and higher-order operators
Abstract The renormalization in a Lorentz-breaking scalar-spinor higher-derivative model involving $$\phi ^4$$ ϕ4 self-interaction and the Yukawa-like coupling is studied. We explicitly de-monstrate that the convergence is improved in comparison with the usual scalar-spinor model, so, the theory is...
