Tencent meeting room: https://meeting.tencent.com/dm/NXVVKc7PPZSs

Meeting number: 695-8098-7502

    • 16:00 → 16:05
      Introduction 5m

      General items.

      Speaker: Prof. Kun LIU (Tsung-Dao Lee Institute & Shanghai Jiao Tong University)
    • 16:05 → 16:15
      ATLAS ttWML and ttHML analyses status 10m
      Speaker: Nihal BRAHIMI (Tsung-Dao Lee Institute & Shanghai Jiao Tong University)

      ttWML analysis status:

      • Latest version of the INT note (v07) was posted on Monday incorporating the final unblinded results (inclusive and differential fits) and paper draft (v06) will be released today
      • We will have the analysis closure meeting on Friday at a special Top plenary. Following the closure, we will start circulation within ATLAS and hopefully go public for Moriond EW (CONF conversion)!

      ttHML analysis status:

      • Decision made to adopt the 3D MVA setup for defining the SR discriminant in the 2lSS channel. Working with Jialin to check the MC modeling of all the input training variables to rule out any with poor modeling.
      • Need to decide on the DNN vs BDT architectures for the 3D MVAs after retraining based on the latest group production v0801. The performance in a realistic fit setup will need to be assessed to guide the choice.
      • The option to adopt a looser b-tagging WP for the events selection is being considered as it was shown to result in enhanced MVAs performance. Currently preparing to test the impact of adopting this WP on the template fit fakes estimation.
    • 16:15 → 16:25

      H->Zy: sensitivity improvement in the coming Run 3.

      (new resonance search: similar strategy, probing possible excess in high mass region)

       

      Reproduce the Run 2 result & perspective study of Run 3.

    • 17:00 → 17:10
      DarkSHINE tracker study 10m
      Speaker: Junhua Zhang

      Finished:

      study the map of delta_x and recoil_p in a small p reigon.

      study the map of deflection angle and recoil_p in a full p reigon.

       

      Next to do:

      1. Check the code of theta_1's definition. Since the bad resolution in the figure.

    • 17:10 → 17:20
