We study <a:math xmlns:a="http://www.w3.org/1998/Math/MathML" display="inline"><a:mi>C</a:mi><a:mi>P</a:mi></a:math> violation (CPV) in the sneutrino sector within B-L extension of minimal supersymmetric Standard Model, wherein an inverse seesaw mechanism has been implemented. CPV arises from new superpotential couplings (s)neutrino sector, which can be complex and mixing <c:math xmlns:c="http://www.w3.org/1998/Math/MathML" display="inline"><c:mi>C</c:mi><c:mi>P</c:mi></c:math> 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 <e:math xmlns:e="http://www.w3.org/1998/Math/MathML" display="inline"><e:mrow><e:mn>3</e:mn><e:mtext> </e:mtext><e:mtext> </e:mtext><e:msup><e:mrow><e:mi>ab</e:mi></e:mrow><e:mrow><e:mo>−</e:mo><e:mn>1</e:mn></e:mrow></e:msup></e:mrow></e:math>.
