1. Polarized Scattering Equations for 6D Superamplitudes / Geyer, Yvonne ; Mason, Lionel
We introduce a spinorial version of the scattering equations, the polarized scattering equations, that incorporates spinor polarization data. [...]

2. Two-loop scattering amplitudes from ambitwistor strings: from genus two to the nodal Riemann sphere / Geyer, Yvonne ; Monteiro, Ricardo
We derive from ambitwistor strings new formulae for two-loop scattering amplitudes in supergravity and super-Yang-Mills theory, with any number of particles. [...]

3. Gluons and gravitons at one loop from ambitwistor strings / Geyer, Yvonne ; Monteiro, Ricardo
We present new and explicit formulae for the one-loop integrands of scattering amplitudes in non-supersymmetric gauge theory and gravity, valid for any number of particles. [...]

4. One-loop amplitudes on the Riemann sphere / Geyer, Yvonne ; Mason, Lionel ; Monteiro, Ricardo ; Tourkine, Piotr
The scattering equations provide a powerful framework for the study of scattering amplitudes in a variety of theories. [...]

5. New ambitwistor string theories / Casali, Eduardo ; Geyer, Yvonne ; Mason, Lionel ; Monteiro, Ricardo ; et al
We describe new ambitwistor string theories that give rise to the recent amplitude formulae for Einstein-Yang-Mills, (Dirac)-Born-Infeld, Galileons and others introduced by Cachazo, He and Yuan. [...]
