Abstract:
In July 2025 the Large Hadron Collider collided ^{16}O^{16}O and ^{20}Ne^{20}Ne isotopes in a quest to understand the physics of ultrarelativistic light ion collisions. One of the key motivations for this run was to discover partonic energy loss in systems with a small quark-gluon plasma. In this Letter we combine a Baier-Dokshitzer-Mueller-Peigné-Schiff and Zakharov based model, a weighted path based energy loss prescription, and jewel together with two realistic geometries of the ^{16}O and ^{20}Ne isotopes. The different sizes of the ions affect the energy loss in characteristically different ways depending on the model.
