The role of the Surround Background Tagger for the SHiP experiment — Maximilian Ehlert, Sandra Gerlach, Ievgen Korol, Heiko Lacker, Paul Rosenau, and •Plamenna Venkova — Humboldt University, Berlin, Germany
SHiP, a new general-purpose fixed-target facility is proposed to be constructed at the CERN SPS accelerator complex. The goal is to dump 2 × 1020 protons of 400 GeV momentum on a molybdenum-tungsten target over a time of five years and to search for very weakly interacting long-lived particles with masses below O(10 GeV), such as Heavy Neutral Leptons (HNLs). After stopping hadrons and filtering out muons, the HNLs can decay inside a 50 m long decay vessel, which is enclosed by a surround background tagger (SBT). The decay products of the HNLs are detected in a subsequent spectrometer. The talk discusses the role of the SBT to suppress background in the offline analysis.
