Identifying the Higgs Spin and Parity in Decays to Z Pairs

Higgs decays to Z boson pairs may be exploited to determine spin and parity of the Higgs boson, a method complementary to spin–parity measurements in Higgsstrahlung. For a Higgs mass above the on-shell ZZ decay threshold, a modelindependent analysis can be performed, but only by making use of additional angular correlation effects in gluon-gluon fusion at… CONTINUE READING
