Scattering Amplitudes For All Masses and Spins
Nima Arkani-Hamed, Tzu-Chen Huang, Yu-tin Huang
We introduce a formalism for describing four-dimensional scattering amplitudes for particles of any mass and spin. This naturally extends the familiar spinor-helicity formalism for…
On the exactness of soft theorems
Andrea L. Guerrieri, Yu-tin Huang, Zhi-Zhong Li +1
Soft behaviours of S-matrix for massless theories reflect the underlying symmetry principle that enforces its masslessness. As an expansion in soft momenta, sub-leading soft theore…
S-matrix singularities and CFT correlation functions
Carlos Cardona, Yu-tin Huang
In this note, we explore the correspondence between four-dimensional flat space S-matrix and two-dimensional CFT proposed by Pasterski et al. We demonstrate that the factorization…
