Results from Fixed-Target Collisions at LHCb

The LHCb spectrometer has the unique capability to function as a fixed-target experiment by injecting gas into the LHC beam pipe near the LHCb interaction point while proton or ion beams are circulating. The resulting fixed-target collisions cover an unexplored energy range, intermediate to previous fixed-target experiments and the top RHIC energy for AA collisions, and allow systems of different size to be studied. In this talk, recent results on quarkonia and open charm production in pNe and PbNe fixed-target collisions will be presented and compared with various theoretical models of quarkonia production, charm hadronization, and transport through the nucleus. The status and physics prospects of LHCb’s fixed-target upgrade for Run 3, SMOG2, will also be discussed.
