Request TypeSimulated background embedding (generator with real data as background for noise / pile-up studies)
DescriptionEmbedding of D0 and anti-D0 with flat pt into zerobias events + Hijing for B->D studies

Basically extending request no. 20182101 to higher pt

Based on authors request: https://drupal.star.bnl.gov/STAR/system/files/EmbedRequest_BtoD.pdf

Particle:
D0, anti-D0 Embedd into zerobias events + HIJING
decay channel: D0->π+K-, anti-D0->π-K+
Library: SL16d
Production chain: Official P16id production chain + simulators

event:
VzTpc :(-6, 6) cm.
|Vz_TPC-Vz_VPD|<3cm

D0/anti-D0  distribution:
Phi : (0, 2pi) flat
Rapidity: (-1.1, 1.1) flat
pT:(1.8, 10) GeV/c , flat
 

number of events(for each particle species) vs Hijing centrality classes:

Centrality     HIJING b(fm)  #Events  #La_c(aLa_c)/Event

70-80%         12.86               1M             1

60-70%         11.95               500k             2

50-60%     11.05-11.08         340K            3

40-50%     10.11-10.16         170K            6

30-40%          9.0-9.2              112K            9

20-30%          7.8-8.2              85K          12

10-20%          4.5-7.8              63K          16

0-10%               0-4.5              50K          20

2.3M events  for  D0 a and the same  for anti-D0 =>together 4.6M
