SLB Nov24 Hackathon: Tune BToXuTauNu lines (Hadronic and Muonic Tau)

Tune Hlt2 lines and TURN OFF spruce lines.

Kaon cuts applied on make_bstoktaunu_muonic, make_bstoktaunu_muonic_fakemu, make_bstoktaunu_muonic_fakek, make_bstoktaunu_hadronic:

   with make_candidate.bind(track_chisq_ndof_max=2.5, 
                             track_ghostprob_max=0.03):
      kaons = make_kaons_from_b(
        pid=F.require_all(F.PID_K > 10, F.PID_K - F.PID_P > 5, F.PID_K - F.PID_MU > 10,
        p_min=12000 * MeV,
        pt_min=1200 * MeV,
        mipchi2_min=60.)

Pion cuts applied on make_b0topitaunu_hadronic:

Same kinematic cuts as kaon but tighten PID

       pid=F.require_all(F.PID_K < -10,
                          F.PID_K - F.PID_P < -5,
                          F.PID_K - F.PID_MU < -10),, ...

Proton cuts applied on make_lbtoptaunu_tautopipipinu:

                 pid=F.require_all(F.PID_P > 12., 
                          (F.PID_P - F.PID_K) > 12.,
                          (F.PID_P - F.PID_MU) > 12.,...

Mother cuts on make_bstoktaunu_muonic, make_bstoktaunu_muonic_fakemu, make_bstoktaunu_muonic_fakek, but with:

    comb_m_min = 1000 * MeV
    comb_m_max = 5000 * MeV
    mcorr_min = 2500 * MeV
    mcorr_max = 6500 * MeV
    vchi2pdof_max = 2.5
    bpvdira_min = 0.999
    bpvfdchi2_min = 180.
    comb_doca_max = 0.07 * mm

Mother cuts applied on make_bstoktaunu_hadronic:

Same cuts as make_bstoktaunu_hadronic as above but with

    comb_doca_max = 0.035 * mm

Mother cuts applied on make_b0topitaunu_hadronic:

Same cuts as make_b0topitaunu_hadronic as above but with

    comb_doca_max = 0.035 * mm

Mother cuts applied on make_lbtoptaunu_tautopipipinu:

    comb_m_max = 6000. * MeV
    comb_doca_max = 0.055 * mm

Plots used to decide these for block 8 data are here. Note there is no MC sample for these (so the blue that you see in the data are Lb -> p mu nu and Bs -> K mu nu.
