A bstract Heavy Neutral Leptons (HNLs) are hypothetical particles predicted by many extensions of the Standard Model. These can, among other things, explain origin neutrino masses, generate observed matter-antimatter asymmetry in Universe and provide a dark matter candidate. The SHiP experiment will be able to search for HNLs produced decays heavy mesons travelling distances ranging between $$ \mathcal{O} <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mi>O</mml:mi>...
