The electric (EDM) and magnetic (MDM) dipole moments of particles are powerful tools to explore fundamental laws of physics. EDM,strongly suppressed in the standard model, offers a perfect “smoking gun”sign of new physics. Baryons’ MDM provides insight of QCD models and might probe quark substructure. Study of EDM and MDM is usually carried out analyzing spin precession in a magnetic dipole, but such scheme excludes fast-decaying particles travelling only very short distances (i.e.,few cm). Such is the case for $\Lambda_C$ and $\Xi_C$ charmed baryons, whose EDM and MDM has still not been directly measured. A chance for this measure is granted by bent crystals. Indeed,spin precession equivalent to hundreds of Tesla dipole may occur for particle crossing a bent crystal in planar channeling state.The crystal-assisted setup exploiting LHCb detectors proposed by SELDOM will be presented, with focus in the design and production of bent crystal suitable for such experiment and compatible with operation in LHC.
