VBS Wgamma: paper circulation

DarkShine: Rare process validation debug done, making validation plots

 

 

17:00 → 17:10 Status

Speaker: Qibin LIU (TDLI, SJTU)

Last week:

Dark photon comb: derive the results of mH up to 2TeV, correlated/decorrelated/stat-only resuts.

Fast calosim: first version of paper draft. will discuss tonight on the following todos.

 

Next week:

Dark photon comb: check single channel stat-only results with reference. 

Fast calosim: revise results plots. revise introduction part. fill references.

Sbb: setup theory syst framework. re-calculate scale syst for signal samples and check with previous results. derive truth distribution and check with reco to validate the framework.

Self-learning jet tagging: finish the masked model and call for a meeting

Dark Photon Combination

• VBF-recast: rerun the VBF-channel VBF-signal-only limits for high Higgs mass points (2, 2.5 and 3 TeV) with the new PDF uncertainties computed using the averaging procedure ---> resolve the abnormally large spikes in the 2sigma band in high-mass region; the reproduced limits (for 2 TeV) are now better matched with the published limits.
• Add ggF H->yyd signal contribution.
  • Problem in PDF uncertainties of ggF H-2.5-TeV signal: the sample derivations do not store the PDF4LHC weight values ---> cannot compute the PDF variations ---> take the PDF uncertainties of ggF H-3-TeV signal as a conservative method.
• VBF - monophotonRECAST combination: Qibin has performed the stat. combination (with different syst. correlation schemes) for up to 2 TeV mass using the available workspaces. Sensitivity is still driven by the combination; combination for 2.5 and 3 TeV will be performed when their VBF-channel workspaces are available.

GW-collider inverse problem:

• discuss with VQ how to construct the likelihood for GW signal measurement from LISA ---> then how to stat. combine with the collider measurement to obtain the exact overlapped region in the model parameter space.
• discuss 2 papers: https://arxiv.org/pdf/2106.05984.pdf and https://arxiv.org/pdf/2209.13551.pdf

HCAL simulation： Finalize paper for NST. besides of the modification from JINST comments, we add the veto in_eff for muon,so as the related explanation.

HCAL  hardware : (1) N.P.E test: has been done for 1 cm pieces (5_1_2& 5_1_3), 2 cm pieces are under testing (2) noise test: define the method for setting the cut (one N.P.E)
