Abstract
The FASER{\nu} experiment has detected the first neutrino events coming from LHC. Near future high-statistic neutrino samples will allow us to search for new physics within the neutrino sector. Motivated by the forthcoming promising FASER{\nu} neutrino data, and its succesor, FASER{\nu}2, we study its potential for testing the unitarity of the neutrino lepton mixing matrix. Although it would be challenging for FASER{\nu} and FASER{\nu}2 to have strong constraints on this kind of new physics, we discuss its role in contributing to a future improved global analysis.
