Very forward jets in CMS with CASTOR

The Cherenkov sampling calorimeter, CASTOR, is designed to measure the production of secondary particles at very forward rapidity. Due to its unprecedented rapidity acceptance, very forward jet studies in high energetic collisions provide a unique sensitivity to low-$x$ as well as nonlinear evolution effects. Jets in the CASTOR acceptance are reconstructed with the anti-$k_{t}$ jet clustering algorithm. In this talk, the jet measurements performed with the CASTOR detector during the LHC Run2 era are presented.
