# Fracture Functions from $\Lambda^0$ Leptoproduction for Target Remnant Description

## Speakers

• Sereres JOHNSTON

## Content

Fracture functions describe the production of hadrons in the target remnant region. Similar to both fragmentation and structure functions, these non-perturbative objects are measurable, universal functions that can be extracted from experiment in one kinematic regime and used to compute reactions at different scales, factorizing and evolving in a predictable way. The Jefferson Lab CLAS EG2 data-set, which measured high statistics 5-GeV electron-scattering data binned in variables such as $Q^2$, $x_B$ and $\nu$, offers a rich opportunity to extract fracture functions using electron triggered processes. This talk will describe the ongoing work to extract fracture functions from the $\Lambda^0$ yields identified in binned EG2 data.
