Draft: High-multiplicity charm production
The full and sprucing lines is used for charm hadron femtoscopy correlation function study. To extract the source function, we need high-multiplicity events. The femtoscopy study include D(D*,D+,..)+p/K/pi. An important physical background on the correlation function of D-h comes from the decay of other charm mesons. For example, to study the correlation function of D0-K, we need to study that of X-K for every kind of particle X that can decay to D0. That's why, we keep as much as charm production lines, adding a very high multiplicity threshold to it (PVNTRACKS of BestPV > 190, less than 1% data left), and let them be unprescaled. These lines include:
- D(s)p->K- K+ pi+
- D0 --> K- pi+ pi+ pi+
- D0 --> K- pi+
- D0 --> KS0(DD) K+ K-
- D0 --> KS0(LL) K+ K-
- D0 --> KS0(DD) pi+ pi-
- D0 --> KS0(LL) pi+ pi-
- Double charm of opposite sign
- Double charm of same sign
- D+ -->K- Pi+ Pi+
- D*+ --> D0 pi+, D0 --> K- pi- pi+ pi+
- D*+ --> D0 pi+, D0 --> K- pi+
- D*+ --> D0 pi+; D0 --> KS0(DD) K+ K-
- D*+ --> D0 pi+; D0 --> KS0(LL) K+ K-
- D*+ --> D0 pi+; D0 --> KS0(DD) pi+ pi-
- D*+ --> D0 pi+; D0 --> KS0(LL) pi+ pi-
- Lc+ --> p+ K- pi+
- Xic0 --> p+ K- K- pi+
- Xic+ --> p+ K- pi+
Most of the lines have 0 Mb/s data flow. And most of the non-zero rate are far below 1Mb/s, two lines exceed the 1Mb/s, one 1.8 and the other 1.3Mb/s. The output for rate test is in the directory.
