Unformatted text preview: b . The main background is Wb b production, where the b s were produced through a gluon, photon or a Z . On the same plot, show the b b invariant mass distribution M b b for the Wh signal and the Wb b background. Notice that because of the very small Higgs width h , the signal will peak very sharply at M b b = m h . In reality, however, the energy of the b-jets is not perfectly measured, which results in an uncertainty in M b b of order 10%. An easy way to account for the poor mass resolution and thus make our plot more realistic, is to simply inate the Higgs width h to 0 . 1 m h 12 GeV. Hint: You may need to use the option regularization to constrain M b b near the s-channel gluon, photon, Z or H resonances. Problem 3. Higgs production at the LHC. Repeat Exercise 1, but for the case of Higgs production in vector-boson fusion at the LHC ( pp collider, E CM = 7 TeV). 1...
