Qualitative Aspects of Polarization Distributions In Excited Heavy Hadron Productions
نویسنده
چکیده
Within the context of flux tube models, heavy quark fragmentation takes place through the breaking of flux tubes with the production of a (di)quarkanti(di)quark pair. It is found that the (di)quark produced are more likely to be found in an Lz = 0 state. This naturally leads to an supression of the polarization distribution parameters w3/2 and w̃1 for (D1,D ∗ 2) and (Λc1,Λ ∗ c1) production respectively. The corresponding parameter w1 for (Σc,Σ ∗ c) production, however, is not suppressed, in agreement with the CLEO results but not the DELPHI one. Implications on the measurements of ΛQ polarizations

How to probe the spin – dependent gluon distributions †
Two–spin asymmetries A π 0 LL are calculated for various types of spin–dependent gluon distributions. It is concluded that the E581/704 data on A π 0 LL do not necessarily rule out the large gluon polarization but restrict severely the x dependence of its distribution. Moreover, A J/ψ LL are calculated for the forthcoming test of spin–dependent gluon distributions. The advent of so–called " the...
متن کاملProbing Polarized Gluon Distributions through Charmed Hadron Production in Polarized pp Collisions at BNL–RHIC Energy
In order to extract information about behavior of polarized gluons in the nucleon, charmed hadron productions, i.e. D meson and Λ+c baryon productions, are studied in polarized pp reactions at BNL-RHIC energy. For these processes, the spin correlation asymmetry ALL between the target proton and the produced charmed hadron, and its statistical sensitivity δALL are calculated as functions of tran...
متن کاملExcited charmed baryon decays and their implications for fragmentation parameters.
The production of the excited charmed baryon doublet Lc * via fragmentation is studied. An analysis of the subsequent hadronic decays of the doublet within the framework of heavy hadron chiral perturbation theory produces expressions for both the angular distribution of the decay products and the polarization of the final state heavy baryon in terms of various nonperturbative fragmentation para...
متن کاملProduction, decay, and polarization of excited heavy hadrons.
We discuss the production via fragmentation of excited heavy mesons and baryons, and their subsequent decay. In particular, we consider the question of whether a net polarization of the initial heavy quark may be detected, either in a polarization of the final ground state or in anisotropies in the decay products of the excited hadron. The result hinges in part on a nonperturbative parameter wh...
متن کاملAnalysis of weak-interaction effects in high energy hadron-hadron collisions.
Parity-violating (pv) effects in inclusive hadron and jet productions in high energy hadronhadron collisions are analyzed. Such effects arise from the interference between strong and weak amplitudes. This interference gives rise to a nonzero value of the pv parameters AL and PL, where AL measures the difference in the inclusive cross sections of, for example, p + p → jet +X (X=anything), with o...
