The tracking spectrometer consists of three tracking stations, and the IFT is an identical tracking station. Each tracking station consists of three double-layers of single-sided silicon microstrip detectors. A tracking layer is made up of eight silicon strip modules which are spares from the ATLAS experiment's SCT barrel detector [36], giving a total of 96 modules used in FASER. A module is shown in Fig. 3.2 (left) and is approximately6×12cm2, and they are arranged in two columns of four modules to give a24×24cm 2 active detector area, called a tracking layer, which covers the full aperture of the FASER magnets. A photo of a tracking layer is shown in Fig. 3.2 (right). The modules are operated with a bias voltage of 150 V, providing a hit efficiency"},{"citing_arxiv_id":"2604.17564","ref_index":82,"ref_count":1,"confidence":0.88,"is_internal_anchor":true,"paper_title":"Search for the single production of vector-like quarks decaying into a W boson and a b quark using single-lepton final states in proton-proton collisions at $\\sqrt{s}$ = 13 TeV","primary_cat":"hep-ex","submitted_at":"2026-04-19T18:10:43+00:00","verdict":"ACCEPT","verdict_confidence":"LOW","novelty_score":4.0,"formal_verification":"none","one_line_summary":"No significant excess observed in search for vector-like quark single production to Wb, setting 95% CL upper limits on κ_W as low as 0.086 near 1.4 TeV mass and excluding masses below 2.4 TeV at κ_W=0.2.","context_count":1,"top_context_role":"method","top_context_polarity":"use_method","context_text":"1007/s41781-024-00121-4, arXiv:2404.06614.
