Cern SPS'te ship deneyinin saklı parçacıklara hassasiyeti

New Physics (NP) can be explored by connecting the Hidden Sector to the Standard Model (SM) through new (hidden) particles, which are very feebly interacting and have masses below the Fermi scale. The SHiP (Searching for Hidden Particles) experiment aims to search for hidden particles produced by transferring SPS proton beams into the Beam Dump Facility (BDF)'s fixed-target. In this thesis, the SHiP's sensitivity to two hidden particles, Dark Photon (DP) and Axion-Like-Particle (ALP), is studied. In order to achieve this goal, a chain of physics implementation - MC grid production - sensitivity analysis is composed, which is used to exclude a phase-space contour with a 90% confidence level. The results show that SHiP promises unique sensitivity regions which have not been investigated or considered previously.
