Signatures of Higgs Bosons in the Top Quark Decay Channel at Hadron Colliders
read the original abstract
We analyze some signatures of neutral Higgs bosons, produced in high energy proton (anti)proton collisions, which decay primarily to top quarks. This channel is clouded by a large irreducible $t\bar t$ background. We investigate the $t\bar t$ invariant-mass distribution in the lepton+jets decay mode of $t\bar t$ and a $t\bar t$ spin-spin correlation in the dilepton decay mode. At the LHC such Higgs bosons can be detected in the $t\bar t$ invariant-mass spectrum, and the spin-spin correlation studied by us is also sensitive to a Higgs boson if this particle has a sizeable pseudoscalar component.

Polarization, Maximal Concurrence, and Pure States in High-Energy Collisions
Local spin polarization imposes an upper bound on concurrence in two-qubit systems that is saturated by pure states, and this bound lowers maximal entanglement in the polarized e+e- to Z to qqbar process relative to t...

Polarization, Maximal Concurrence, and Pure States in High-Energy Collisions
An upper bound on concurrence is derived for fixed local polarizations in two-qubit systems, saturated by pure states in some cases, and applied to show reduced maximal entanglement in polarized q qbar pairs from pari...
