A bstract We consider tree-level off-shell currents of two massive particles and n massless bosons in the classical limit, which can be fused into the classical limit of n+ 2 scattering …

A bstract We present a map between the tree-level Standard Model Effective Theory (SMEFT) in the Warsaw basis and massive on-shell amplitudes. As a first step, we focus on …

A bstract The novel massive spinor-helicity formalism of Arkani-Hamed, Huang and Huang provides an elegant way to calculate scattering amplitudes in quantum chromodynamics for …
A bstract We explore the on-shell recursion for tree-level scattering amplitudes with massive spinning particles. Based on the factorization structure encoded in the same way by two …
Inspired by recent progress on classical limits of scattering amplitudes, we show that hard thermal loops can be obtained from classical limits of off-shell currents. The classicality of …

A bstract The standard argument why gravity is not renormalisable relies on direct powercounting of Feynman graphs to estimate the degree of UV divergence. In several …
We present SpinorsExtras package implementing massive spinor-helicity formalism in Mathematica on top of S@ M package. Package defines new objects for Mathematica …

BCFW deformation has served as an extremely useful tool in providing a recursive approach in studying color-ordered gauge amplitudes. This procedure has also been generalized to …
Abstract The Standard Model (SM) is an effective description of Nature and experimental evidences indicates that beyond SM physics ought to exist. The series of the LHC null …
