### plan for TGC measurement

Zhijun Liang

• Calculate A_W(pTΥ) , C_W(pTγ) as a function of photon pT for SM/ATGC sample

• Binning (45,55), (55,65),(65,75),(75,85),(85,105),(105,120),(>120)GeV.

• Compare C_W(pTγ) in SM sample with C_W(pTΥ) in ATGC sample, check if the discrepancy is within 5%.

• C(W)[pT] term in SM/ATGC samples agree within 5%

• use C_W(pTγ) in SM sample and quote the discrepancy between ATGC samples and SM samples as systematic of C_W(pTγ).

• A(W) [pT] vary with different ATGC setting

• Generate 50X50 grid in “λ/Δκ “, “h3/h4” phase space

calculate A_W[pTg] (λ;Δκ), k factor[pTg] (λ;Δκ) and

σ[pTg] (λ;Δκ) in these 2500 points.

• Wgamma :

• Δκ [-1.25,1.25] (∧=3TeV,n=2), scan in steps of 0.05

• λ[-0.25,0.25] (∧=3TeV,n=2), scan in steps of 0.01

• Zgamma,,

• h3[-0.05,0.05](∧=2TeV,n=3), scan in steps of 2e-3

• H4[-0.000125, 0.000125] (∧=2TeV,n=4)

in steps of 5e-6
