1 Study of u-channel contribution at TDA region [1] Numerical analysis due to small amount of data after applying kinematical cuts for TDA : No EVENT = ~22k [2] Acceptance recalculation [3] Apply the constant FRAD correction [4] Kinematical range Q2 = 1.75, 2.05, 2.35, 2.65, 2.95, 3.35, 3.85, 4.35 GeV2 -t = -6.6, -5.8, -5.0, -4.2, -3.4GeV2 : Δt = 0.8GeV2 -u = -1.8, -1.4, -1.0, -0.6, -0.2GeV2 : Δu =0.4GeV2
