Analysis shows equivalence of scattering amplitudes in biadjoint scalar theory and nonlinear sigma model, suggesting a common framework for understanding.
Key Points
Scattering amplitudes in biadjoint scalar theory and nonlinear sigma model can be viewed as equivalent.
All amplitudes arise from evaluating the KLT kernel at different kinematic points, supporting universality.
The alpha prime shift complements the previously proposed delta shift, linking distinct quantum field theories.
This framework demonstrates the inherent equivalence of amplitudes across different theories through string theory.
