Primary Decompositions in Lorentz-Covariant Rings
Giuseppe De Laurentis, David Tai
An effective strategy for constructing compact representations of integral coefficients in scattering amplitudes is to make their singularity structure manifest. This is naturally…
Lips: p-adic and singular phase space
Giuseppe De Laurentis
I present new features of the open-source Python package lips, which leverages the newly developed pyadic and syngular libraries. These developments enable the generation and manip…
Constructing Compact Ansätze for Scattering Amplitudes
Giuseppe De Laurentis, Ben Page
In these proceedings, we discuss the recent approach of Ref. [1] for the construction of compact Ansätze for scattering amplitudes. The method builds powerful constraints on the an…
Ansätze for Scattering Amplitudes from -adic Numbers and Algebraic Geometry
Giuseppe De Laurentis, Ben Page
Rational coefficients of special functions in scattering amplitudes are known to simplify on singular surfaces, often diverging less strongly than the naïve expectation. To systema…
