γγ->HH Study Report Nozomi Maeda Hiroshima Univ.
Previous meeting choose Signal(Background) reaction. Cut with some parameter.
today ’ s topic ・ About Cut condition and result
choose solution solutions are... (H1, H2) = (j1+j2, j3+j4), (H1, H2) = (j1+j3, j2+j4), (H1, H2) = (j1+j4, j2+j3), (H1, H2) = (j3+j4, j1+j2), (H1, H2) = (j2+j4, j1+j3), (H1, H2) = (j2+j3, j1+j4) one solution that has smallest(largest) parameter will be choosen.
Cut parameter Number of tracks Reconstructed particle mass(choosen solution) Cos j1-j2(choosen solution) χ 2 (assume Higgs, assume W-boson)
Cut condition and result Ntrack > 100 Signal : > 340 Background : > 10 Mass > 90 Signal : > 90 Background : > < CosTheta < 0 Signal : > 69 Background : > 0
χ 2 2D Plot
Cut condition and result x :χ 2 (assume Higgs) y :χ 2 (assume W-boson) condition : y + (250/75)x < 250 Signal : > 833 Background : > 83
