Dear Conveners,

We would also like to request the embedding data for Au+Au 3.9 GeV again:

-----------------------------------------------------------

1) Lambda->p+pi-

 -----------------------------------------------------------   

2) H4L->4He+pi-   

   *lifetime: 218 ps   

-----------------------------------------------------------

3) H3L->3He+pi-

 *H3L lifetime: 221 ps   

-----------------------------------------------------------    

4) H3L->d+p+pi- (free 3body) *H3L mass: 2991MeV/c2 

*H3L lifetime: 221 ps   

-----------------------------------------------------------   

5) H3L -> d + "Λ" (100% branch ratio), "Λ"-> p + pi- (100% branch ratio) 

*H3L mass: 2991 MeV/c2 

*H3L lifetime: 221 ps   

*”Λ” mass: 1115.28 MeV/c2   

*”Λ” mean lifetime: 10^{-20} s

*d mass/lifetime: 1875.613 MeV/stable

*p,π-: Normal particles 

-----------------------------------------------------------   

 

Each above decay channel has the same settings as following: 

-----------------------------------------------------

TriggerSetup: production_7p3GeV_fixedTarget_2020  

Production: P23ie    

Library: SL23e  

Trigger: 730000  

Event cuts: -198cm < Vz < 202 cm and (Vx+0.20)^2+(Vy+2.00)^2 ≤ 4 cm   

Centrality: 0-80%    

Events: 2.5M   

Uniform in Rapidity (CMS): [-1.5, 0.8]  

Uniform in pT: [0.0, 5.0]

Uniform in phi: [0, 2π]

List of bad runs: {21035006, 21035025, 21035031, 21035011, 21036012}  

Embedding fraction: 5% of multiplicity  

-----------------------------------------------------    

   

if there are any other information needed, please let us know.   

 

Thank you for your attention.  

  

Best regards,

Subject:  [Star-fcv-l] Embedding request Lambda, H3L and H4L for FXT Au+Au 3.5 GeV

 

Dear Conveners,

For correcting detection efficiency and acceptance of Lambda, $^3_{\Lambda}H$ (H3L) and $^4_{\Lambda}H$ (H4L) in collective flows analysis, 
we would like to request embedding data for following decay channels of above particles for Au+Au 3.5 GeV data again:
-----------------------------------------------------------
1) Lambda-&gt;p+pi-
 -----------------------------------------------------------  
2) H4L-&gt;4He+pi-  
   *lifetime: 218 ps  
-----------------------------------------------------------
3) H3L-&gt;3He+pi-
 *H3L lifetime: 221 ps  
-----------------------------------------------------------   
4) H3L-&gt;d+p+pi- (free 3body) *H3L mass: 2991MeV/c2
*H3L lifetime: 221 ps  
-----------------------------------------------------------  
5) H3L -&gt; d + "Λ" (100% branch ratio), "Λ"-&gt; p + pi- (100% branch ratio)
*H3L mass: 2991 MeV/c2
*H3L lifetime: 221 ps  
*”Λ” mass: 1115.28 MeV/c2  
*”Λ” mean lifetime: 10^{-20} s
*d mass/lifetime: 1875.613 MeV/stable
*p,π-: Normal particles
-----------------------------------------------------------  

Each above decay channel has the same settings as following:
-----------------------------------------------------
TriggerSetup: production_5p75GeV_fixedTarget_2020 
Production: P23ie   
Library: SL23e 
Trigger: 720000 
Event cuts: -198 cm &lt; Vz &lt; 202 cm and (Vx+0.36)^2+(Vy+2.00)^2 ≤ 4 cm  
Centrality: 0-80%   
Events: 2.5M  
Uniform in Rapidity (CMS): [-1.5, 0.8] 
Uniform in pT: [0.0, 5.0]
Uniform in phi: [0, 2π]
List of bad runs: {20355020, 20355021, 21044023, 21045024, 21045025, 21044027, 21044035, 21045004}
