Higgs CAT

Higgs Computed Axial Tomography, an excerpt. The Higgs boson lineshape (. . . and the devil hath power to assume a pleasing shape, Hamlet, Act II, scene 2) is analyzed for the gg ZZ process, with special emphasis on the off-shell tail which shows up for large values of the Higgs virtuality. The effect of including background and interference is also discussed. The main focus of this work is on residual theoretical uncertainties, discussing how much-improved constraint on the Higgs intrinsic width can be revealed by an improved approach to analysis.
