Add charmed-baryon lines with T-track

The following lines are added to the hyperonsTT.py.

• $\Lambda_c^+\to\Lambda\pi^-\pi^+\pi^+$
• $\Xi_c^+\to\Lambda K^-\pi^+\pi^+$
• $\Xi_c^0\to\Xi^-\pi^-\pi^+\pi^+$

Seven lines are added with different combination cases of

$\Xi^-$

and bachelor

$\pi$

and

$K$

.

The rate for additional processes are estimated by hlt1_filtered 2024 minbias samples as

• $\Lambda_c^+\to\Lambda\pi^-\pi^+\pi^+$

rate_LcpToL0PimPipPip_TT_LLL #= 1110033.0 Sum= 74.0 | rate = ( 66.6 +/- 7.7 ) Hz
rate_LcpToL0PimPipPip_TT_DDD #= 1110033.0 Sum= 0.0  | rate = ( 0.0 +/- 0.0 ) Hz

• $\Xi_c^+\to\Lambda K^-\pi^+\pi^+$

rate_XicpToL0KmPipPip_TT_LLL #= 1110033.0 Sum= 8.0 | rate = ( 7.2 +/- 2.5 ) Hz
rate_XicpToL0KmPipPip_TT_DDD #= 1110033.0 Sum= 0.0 | rate = ( 0.0 +/- 0.0 ) Hz

• $\Xi_c^0\to\Xi^-\pi^-\pi^+\pi^+$

rate_Xic0ToXimPimPipPip_TTL_LLL #= 1110033.0 Sum= 9.0  | rate = ( 8.1 +/- 2.7 ) Hz
rate_Xic0ToXimPimPipPip_TTD_LLL #= 1110033.0 Sum= 10.0 | rate = ( 9.0 +/- 2.8 ) Hz
rate_Xic0ToXimPimPipPip_TTD_DDD #= 1110033.0 Sum= 0.0  | rate = ( 0.0 +/- 0.0 ) Hz

Here, the 0 rate is due to the low efficiency of the decay process itself. A study based on signal MC sample is performed to make sure there are some outputs.

Since some selection criteria are updated according to the 2024-condition signal MC samples, we re-estimated the rates of all the remaining lines.

rate_Xic0ToL0KmPip_TT_LL #= 1110033.0 Sum= 100.0 | rate = ( 90.0 +/- 9.0 ) Hz
rate_Xic0ToL0KmPip_TT_DD #= 1110033.0 Sum= 63.0  | rate = ( 56.7 +/- 7.1 ) Hz

rate_Xic0ToXimPip_TTL_L #= 1076544.0 Sum= 84.0 | rate = ( 78.0 +/- 8.5 ) Hz
rate_Xic0ToXimPip_TTD_L #= 1110033.0 Sum= 27.0 | rate = ( 24.3 +/- 4.6 ) Hz
rate_Xic0ToXimPip_TTD_D #= 1110033.0 Sum= 59.0 | rate = ( 53.1 +/- 6.9 ) Hz

rate_XicpToXimPipPip_TTL_LL #= 1110033.0 Sum= 61.0 | rate = ( 54.9 +/- 7.0 ) Hz
rate_XicpToXimPipPip_TTD_LL #= 1110033.0 Sum= 39.0 | rate = ( 35.1 +/- 5.6 ) Hz
rate_XicpToXimPipPip_TTD_DD #= 1110033.0 Sum= 6.0  | rate = ( 5.4 +/- 2.2 ) Hz

TODO:

• The estimation of the rate is ongoing.
• Import the Lambda builder from standard_particles.py when !2645 (merged) is ready.
