Charmed Hadron Production in Polarized pp Collisions†
To extract information about polarized gluons in the proton, production of charmed hadrons, in particular, Λc baryon in pp collisions was studied. We calculated the transverse momentum distribution and the pseudo-rapidity distribution of the spin correlation asymmetry ALL between the initial proton and the produced Λc . Those statistical sensitivities were also calculated under the condition of...
متن کاملPerspectives in Polarized Leptoproduction ∗
We discuss specific observables that can be measured in deep inelastic leptoproduc-tion in the case of 1-particle inclusive measurements, namely azimuthal asymmetries and power-suppressed (higher twist) corrections. These quantities contain information on the intrinsic transverse momentum of partons, with close connection to the gluon dynamics in hadrons. The use of polarization in leptoproduct...
متن کاملCharmed Hadron Production in Polarized pp Reactions as a Probe of Polarized Gluons in the Proton†
To probe the behavior of polarized gluons in the proton, we propose the charmed hadron, such as Λ+c and D ∗, production in the forthcoming RHIC experiments. We found that the spin correlation between the target proton and the produced Λ+c baryon might be a good signal for testing models of the polarized gluon distribution in the proton. † Talk presented by K. Ohkuma at the XVI Particle and Nucl...
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 کاملCharmed Hadron Interactions
We compute the scattering lengths of charmed mesons and charmonia scattering with light hadrons in full QCD. We use Fermilab formulation for the charm quark and domain-wall fermions for the light quarks and staggered sea quarks. Four different light-quark masses are used to extrapolate to the physical point. The charmed baryon spectrum is also presented.
