Study of Forward and Backward Fragmentation Processes in Λ⁰ Leptoproduction

Fracture functions are akin to fragmentation functions but describe hadron production in the target remnant rather than current fragmentation region, factorizing and evolving in a predictable way. Like structure functions, fracture functions extracted from an experiment in one kinematic regime can be used to compute reactions at different scales. Recent theoretical predictions have acknowledged the leptoproduction of Λ⁰ hyperon as the best probe to study the fracture functions in semi-inclusive deep-inelastic scattering. Λ⁰ production off deuterium in datasets which can be finely binned in variables such as Q², x_B and ν provide valuable experimental input for the first extraction of fracture functions using electron triggered processes. This talk will describe the ongoing Λ⁰ analysis from 6 GeV CLAS EG2 data-sets with a discussion of both forward and backward fragmentation processes.
