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 ...

ANALYTIC SCATTERING AMPLITUDES FOR QCD [PDF]
Proceedings of the Conference in Honor of C N Yang's 85th Birthday, 2008 By analytically continuing QCD scattering amplitudes through specific complexified momenta, one can study and learn about the nature and the consequences of factorization and unitarity. In some cases, when coupled with the largest time equation and gauge invariance requirement, this approach leads to recursion relations, which greatly simplify the ...

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.

Likelihood equations and scattering amplitudes [PDF]
Algebraic Statistics, 2020 We relate scattering amplitudes in particle physics to maximum likelihood estimation for discrete models in algebraic statistics. The scattering potential plays the role of the log-likelihood function, and its critical points are solutions to rational ...

MHV gluon scattering amplitudes from celestial current algebras [PDF]
Journal of High Energy Physics, 2020 We show that the Mellin transform of an n-point tree level MHV gluon scattering amplitude, also known as the celestial amplitude in pure Yang-Mills theory, satisfies a system of (n−2) linear first order partial differential equations corresponding to (n ...

Full one-loop amplitudes from tree amplitudes [PDF]
, 2008 We establish an efficient polynomial-complexity algorithm for one-loop calculations, based on generalized $D$-dimensional unitarity. It allows automated computations of both cut-constructible {\it and} rational parts of one-loop scattering amplitudes ...

, 2011 We review two novel techniques used to calculate tree-level scattering amplitudes efficiently: MHV diagrams, and on-shell recursion relations. For the MHV diagrams, we consider applications to tree-level amplitudes and focus in particular on the N=4 ...

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.
