Description
The suppression of the structure functions of bound nucleons in nuclei com- pared to those of free nucleons, observed in deep inelastic scattering experiments, is known as the EMC effect. Its origin is an open question and there is no general explanation for it.
The deuteron is a great system to study the EMC effect. It is a bound system, thus the nucleon structure functions are expected to be modified compared by their free nucleon counterpart. On the other side, we can measure the recoil spectator nucleon (tagging) which was not part in the deep inelastic scattering reaction off the deuteron. This allows to determine the initial state of the scattered nucleon.
The Large Angle Detector experiment at Jefferson Lab (LAD) plans to mea- sure the structure function of the neutron on deuteron involving high momentum nucleons, through the spectator tagging method in the DIS process, measuring the recoil proton at large angles. Such as configuration, will reduce final state interactions and result in a clean signal of the DIS measurement and therefore, the structure function.
In this talk, I will present the set-up and the status of the LAD experiment to be run in Fall 2024.
