This AP is designed for MC tuples generation with J/psi \rightarrow \Lambda \overline{\Lambda} sample.
It consists of 3 steps: HLT1 -> HLT2 -> DV
Two HLT1 sequences are used: hlt1_pp_matching_no_ut_1000KHz and hlt1_pp_matching_and_downstream.
hlt1_pp_matching_no_ut_1000KHz
hlt1_pp_matching_and_downstream
