Wilson loops in SYM $N = 4$ do not parametrize an orientable space

Susama Agarwala, Cameron Marcott

In this paper we explore the geometric space parametrized by (tree level) Wilson loops in SYM $N = 4$ . We show that, this space can be seen as a vector bundle over a totally non-nega…

An algorithm to construct the Le diagram associated to a Grassmann necklace

Susama Agarwala, Sian Fryer

Le diagrams and Grassmann necklaces both index the collection of positroids in the nonnegative Grassmannian $G r_{\geq 0} (k, n)$ , but they excel at very different tasks: for example,…

A study in $G_{R, \geq 0}$ : from the geometric case book of Wilson loop diagrams and SYM $N = 4$

Susama Agarwala, Sian Fryer

We study the geometry underlying the Wilson loop diagram approach to calculating scattering amplitudes in the gauge theory of Supersymmetric Yang Mills (SYM) $N = 4$ . By applying the…
