Electromagnetic dipole and quadrupole moment interaction of ${\mathrm{\Omega }}^{\pm }$ baryons with bent crystals at the LHC

Spin rotation of ${\mathrm{\Omega }}^{\pm }$ baryons channeling in a bent crystal at the LHC in addition to EDM measurement open possibility to study ${\mathrm{\Omega }}^{\pm }$ 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.
