Scattering amplitudes in affine gravity [PDF]
Physical Review D, 2021 Affine gravity is a connection-based formulation of gravity that does not involve a metric. After a review of basic properties of affine gravity, we compute the tree-level scattering amplitude of scalar particles interacting gravitationally via the connection in a curved spacetime.

Determination of the scattering amplitude [PDF]
Communications in Mathematical Physics, 1984 The problem to determine the elastic scattering amplitude from the differential cross-section by the unitarity equation is reexamined. We prove that the solution is unique and can be determined by a convergent iteration if the parameter λ=sin μ of Newton and Martin is bounded by ...

Dual Identities inside the Gluon and the Graviton Scattering Amplitudes [PDF]
, 2010 Recently, Bern, Carrasco and Johansson conjectured dual identities inside the gluon tree scattering amplitudes. In this paper, we use the properties of the heterotic string and open string tree scattering amplitudes to refine and derive these dual ...

Three-loop helicity amplitudes for four-quark scattering in massless QCD
Journal of High Energy Physics, 2021 We compute the three-loop corrections to the helicity amplitudes for q q ¯ $$ \overline{q} $$ → Q Q ¯ $$ \overline{Q} $$ scattering in massless QCD. In the Lorentz decomposition of the scattering amplitude we avoid evanescent Lorentz structures and map ...

Protostring scattering amplitudes [PDF]
Physical Review D, 2016 We calculate some tree level scattering amplitudes for a generalization of the protostring, which is a novel string model implied by the simplest string bit models. These bit models produce a lightcone worldsheet which supports $s$ integer moded Grassmann fields.
