Strangeness studies in LHCb fixed-target collisions

Leveraging on the injection of noble gases into the LHC accelerator beam-pipe, LHCb has been collecting since 2015 proton- and lead-gas collisions, which give access to the poorly explored high-x and moderate Q2 kinematic region. In particular, studies of strangeness production provides information on hadronization and serve as important inputs to models of particle production in cosmic rays. In this contribution, recent results on strangeness production in fixed-target collisions at LHCb will be presented, including studies for hyperon production and polarization.
