Description
The HH searches are fundamentally constrained by statistical limitations. Enhancing the sensitivity to the HH → bbττ decay channel, the most sensitive process for Higgs pair production in ATLAS, necessitates innovative trigger strategies. Conventional trigger approaches adopted for the HH → bbττ channel in Run 2, focusing solely on di-τ triggers have faced challenges in capturing the full spectrum of events. The ATLAS collaboration is considering for the Run 3 analysis the usage of di-b-jet triggers in addition to improved di-τ triggers and implemented also a new b+tau trigger at the start of 2024 for increasing the trigger selection efficiency for the HH → bbττ signal. By this point, the ATLAS experiment has already recorded a remarkable integrated luminosity of 180 fb⁻¹ of Run 3 data, larger than the total Run 2 luminosity, with an additional 1.5 years of data collection remaining. This advancement is a crucial step toward overcoming current limitations and improving the efficiency of the HH → bbττ analysis.
