    • New factorization relations for nonlinear sigma model amplitudes 

      Bjerrum-Bohr, Niels Emil Jannik; Gomez, Humberto; Helset, Andreas (American Physical Society, 2019-02-15)
      We obtain novel factorization identities for nonlinear sigma model amplitudes using a new integrand in the Cachazo-He-Yuan double-cover prescription. We find that it is possible to write very compact relations using only ...
    • New factorization relations for Yang-Mills amplitudes 

      Bjerrum-Bohr, Niels Emil Jannik; Damgaard, Poul Henrik; Gomez, Humberto (American Physical Society, 2019-01-15)
      A double-cover extension of the scattering equation formalism of Cachazo, He, and Yuan leads us to conjecture covariant factorization formulas of n-particle scattering amplitudes in Yang-Mills theories. Evidence is given ...
