A QCD Analysis of Polarised Parton Densities
We present the results of a QCD fit to global data on deep-inelastic polarised lepton-hadron scattering. We find that it is possible to fit the data with strongly broken SU(2) flavour for the polarised sea densities. This can easily be tested in W production at polarised RHIC. The data fails to pin down polarised singlet sea quark and gluon densities. We explore the uncertainties in detail and ...
متن کاملThe Λ b → plν̄ decay in perturbative QCD
We develop perturbative QCD factorization theorems for the exclusive semileptonic heavy baryon decay Λb → plν̄, in which the relevant hadronic form factor is expressed as the convolution of a hard subamplitude with the Λb baryon wave function and the proton wave function. The specific evolution scale for the proton wave function, determined from the best fit to the data of the proton form factor...
متن کاملThe possible Σ-Λ mixing in QCD Sum Rule
We calculate the on-shell Σ-Λ mixing parameter θ with the method of QCD sum rule. Our result is θ(m Σ ) = (−)(0.5 ± 0.1) MeV. The electromagnetic interaction is not included.
متن کاملSemileptonic Λ b decay to excited Λ c baryons at order Λ QCD
Exclusive semileptonic Λb decays to excited charmed Λc baryons are investigated at order ΛQCD/mQ in the heavy quark effective theory. The differential decay rates are analyzed for the Jπ = 1/2− Λc(2593) and the J π = 3/2− Λc(2625). They receive 1/mc,b corrections at zero recoil that are determined by mass splittings and the leading order Isgur-Wise function. With some assumptions, we find that ...
متن کاملQCD Sum Rule for Λ ( 1405 )
Motivated by the recently constructed interpolation field for S11(1535), we propose a new interpolating field for Λ(1405). Using this current, we calculate the mass of Λ(1405) based on the conventional QCD sum rule analysis. By calculating the Wilson coefficients up to dimension 8 operators and taking into account the mass corrections from s-quark, we find the calculated mass of Λ(1405) to be v...
