THE ROLE OF QUARK POLARIZATION IN HEAVY QUARK FRAGMENTATION

Authors: not saved

Abstract:

We calculate the exact fragmentation functions for c and b quark fragmentation taking into account the spin orientation of the initial heavy quark in the form of analytical and rather simple expressions. Our calculations show that spin orientation may have an important effect on the fragmentation spectrum. This effect is more striking in the cases of c ?D, D*; c? ? , ? , and ?B , B *.

Heavy quark fragmentation functions in the heavy quark effective theory.

We calculate fragmentation functions for a b-quark to fragment into color-singlet P-wave bound states c̄b in the Heavy Quark Effective Theory with the exact account of O(1/mb) corrections. We demonstrate an agreement of the obtained results with the corresponding calculations carried out in quantum chromodynamics. Introduction. The study of heavy quarkonia properties is a subject of much current...

Heavy-Quark Fragmentation

We study perturbative and non-perturbative aspects of heavy-quark fragmentation into hadrons, emphasizing the large-x region, where x is the energy fraction of the detected hadron. We first prove that when the moment index N and the quark mass m get large simultaneously with the ratio NΛ/m fixed, the fragmentation function depends on this ratio alone. This opens up the way to formulate the non-...

Heavy-quark Production in the Target Fragmentation Region Heavy-quark Production in the Target Fragmentation Region

Fixed-target experiments permit the study of hadron production in the target fragmentation region. It is expected that the tagging of speci c particles in the target fragments can be employed to introduce a bias in the hard scattering process towards a speci c avour content. The case of hadrons containing a heavy quark is particularly attractive because of the clear experimental signatures and ...

Heavy Quark Fragmentation into Baryons in a Quark-diquark Model

In the framework of the nonrelativistic QCD and a quark-diquark model of baryons we have obtained the fragmentation functions for heavy quark to split into spin-1/2 and spin-3/2 double heavy baryons. It was predicted the production rates as well as the shape of the energy spectra for the cc− and bc−baryons in the region of Zo peak at LEP collider.

Heavy Quark Fragmentation in Deep Inelastic Scattering

We perform an analysis of semi-inclusive production of charm (D-mesons) in neutral current (NC) and charged current (CC) deep inelastic scattering (DIS) at full O(α s). Our calculation is based on the heavy quark scheme developed by Aivazis, Collins, Olness and Tung (ACOT) where we include anO(α s) calculation of quark scattering contributions for general masses and couplings. We review the rel...
