Helicity Density Matrix Formalism and Polarized Processes in QCD
In this thesis, we shall first present helicity density matrix formalism to deal with the polarized processes in quantum chromodynamics(QCD), in which the calculations of the desired cross sections (or asymmetries in many cases) are simplified to take traces of products of helicity density matrices in the underlying particles' (partons, hadrons, etc.) helicity spaces. The parton distribution an...
متن کاملHelicity amplitudes and crossing relations for antiproton proton reactions
Antiproton proton annihilation reactions allow unique access to the moduli and phases of nucleon electromagnetic form factors in the time like region. We present the helicity amplitudes for the unequal mass single photon reaction p p̄ → l+ l− in the s channel including the lepton mass. The relative signs of these amplitudes are determined using simple invariance properties. Helicity amplitudes f...
متن کاملHelicity Amplitudes for Single-Top Production
Single top quark production at hadron colliders allows a direct measurement of the top quark charged current coupling. We present the complete tree-level helicity amplitudes for four processes involving the production and semileptonic decay of a single top quark: W -gluon fusion, flavor excitation, s-channel production and W associated production. For the first three processes we study the qual...
متن کاملHelicity Decomposition for Inclusive J/ψ Production
We present a general method for calculating inclusive cross sections for the production of heavy quarkonium states with definite polarization within the NRQCD factorization approach. Cross sections for polarized production can involve additional matrix elements that do not contribute to cross sections for unpolarized production. They can also include interference terms between parton processes ...
متن کاملQuark Fragmentation and Off-diagonal Helicity Density Matrix Elements for Vector Meson Production
As confirmed by some recent LEP data on φ, K∗ and D∗ production, final state interactions in quark fragmentation may give origin to non-zero values of the offdiagonal element ρ1,−1 of the helicity density matrix of vector mesons produced in ee annihilations: we give estimates for ρ1,−1 of vector mesons with a large xE and collinear with the parent jet, relating its size and sign to the associat...
