Collinear Superspace

Understand

This letter provides a superfield based approach to constructing a collinear slice of $\mathcal{N}$ = 1 superspace.

• The strategy is analogous to integrating out anti-collinear fermionic degrees-of-freedom as was developed in the context of soft-collinear effective theory.
• The resulting Lagrangian can be understood as an integral over collinear superspace, where half the supercoordinates have been integrated out.
• The application to $\mathcal{N}$ = 1 super Yang-Mills is presented.
