B2OC: fixes for the 2024 high mu runs

Alessandro Bertolin requested to merge b2oc_upgrade into 2024-patches
  • fix to reduce the rate of the exclusive spruce line BdToDstpKKPi_DstpToD0Pi_D0ToHHHH
  • fix to the Bs2DsK LTU exclusive spruce line (the fix itself is in the basic builders)

the function make_kaons defined here has some additional arguments, **decay_arguments, that are passed to filter_particles in line 77, this the correct behaviour

instead by mistake the function make_tight_kaons as defined here https://gitlab.cern.ch/lhcb/Moore/-/blob/2024-patches/Hlt/Hlt2Conf/python/Hlt2Conf/lines/b_to_open_charm/builders/basic_builder.py#L142-152 is not passing the **decay_arguments to filter_particles in line 148 but just p_min=p_min, pt_min=pt_min

as a consequence without this fix the LTU line is being run with the default cut F.MINIPCHI2 > 4 instead of the required > 0 needed to select also prompt tracks
