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>...

Dark photons are hypothetical massive vector particles that could mix with ordinary photons. The simplest theoretical model is fully characterised by only two parameters: the mass of dark photon m$_{\gamma^{\mathrm{D}}}$ and its mixing parameter photon, $\varepsilon$. sensitivity SHiP detector reviewed for in range between 0.002 10 GeV. Different production mechanisms simulated, decaying to pairs visible fermions, including both leptons quarks. Exclusion contours presented compared those...
In the framework of Future Circular Collider Study a new septum magnet concept ("SuShi") has been developed, and prototype was built at Wigner RCP, tested FREIA facility Uppsala University.

Following a successful commissioning period, the multiturn extraction (MTE) at CERN Proton Synchrotron (PS) has been applied for fixed-target physics programme Super (SPS) since September 2015.
