DT trigger primitive efficiency study for Phase 2 upgrade

In view of the High-Luminosity LHC upgrade, the new Analytical Method (AM) algorithm optimizes Trigger Primitive generation in the CMS Drift Tubes (DT). This study evaluates the reconstruction efficiency of the AM algorithm across DT chambers, comparing it directly with offline segment performance. Using simulated events under realistic pile-up conditions at 14 TeV, the results demonstrate that the AM algorithm maintains extremely high efficiency and achieves performance fully compatible with offline reconstruction, validating its readiness for the Phase 2 upgrade.
