Abstract

Spin rotation of $\Omega^{\pm}$ baryons channeling in a bent crystal at the LHC in addition to EDM measurement open possibility to study $\Omega^{\pm}$ baryons electric quadrupole moment. Equations for spin and tensor polarization rotation are presented along with the estimations study for values of the effects under discussion.
