We study CP violation (CPV) in the sneutrino sector within B-L extension of Minimal Supersymmetric Standard Model (BLSSM), wherein an inverse seesaw mechanism has been implemented. CPV arises from new superpotential couplings (s)neutrino sector, which can be complex and mixing CP-eigenstates induced by those couplings. leads to asymmetries so called T-odd observables, but we argue that such also lead a wider distribution observables. look at final state where decays lepton, two jets missing transverse momentum Future Circular Collider operating hadron-hadron mode $100$ TeV with luminosity 3~ab$^{-1}$. In order exclude conserving scenario need improve traditional analysis introducing boosted decision trees using both standard kinematic variables observables $Z^{\prime}$ boson not too much above current bounds as portal produce sneutrinos efficiently.
