The Strange Quark Polarisation from Charged Kaon Production on Deuterons
ثبت نشده
چکیده
The strange quark helicity distribution ∆s(x) is derived at LO from the semi-inclusive and inclusive spin asymmetries measured by the COMPASS experiment at CERN. The significance of the results is found to depend critically on the ratio of the s and u quark fragmentation functions into kaons ∫ DK+ s (z)dz/ ∫ DK+ u (z)dz.

Kaon-Nucleus Drell-Yan Processes and Kaon Structure Functions
We investigate the information which could be obtained from Drell-Yan processes with sufficiently intense beams of charged kaons on isoscalar targets. It is found that combinations of K and K− Drell-Yan measurements on isoscalar nuclear targets would allow one to extract the kaon sea quark distributions. These cross sections are also sensitive to the strange valence quark distribution in the ka...
متن کاملRecent Results on Strangeness Production from Cern
New results from NA49 on the production of strangeness in elementary and nuclear reactions are presented. New measurements of charged kaon and pion production have been obtained from 40 AGeV Pb+Pb collisions. The evolution of strange meson yields in nucleus-nucleus interactions is studied as a function of collision energy and system size. Cascade baryon yields are presented for a wide range of ...
متن کاملStranger Still: Kaon Loops and Strange Quark Matrix Elements of the Nucleon*
Intrinsic strangeness contributions to low-energy strange quark matrix elements of the nucleon are modelled using kaon loops and meson-nucleon vertex functions taken from nucleon-nucleon and nucleon-hyperon scattering. A comparison with pion loop contributions to the nucleon electromagnetic (EM) form factors indicates the presence of significant SU(3)-breaking in the mean-square charge radii. A...
متن کاملThe Kaon B-parameter from Two-flavour Dynamical Domain Wall Fermions
We report on the calculation of the kaon B-parameter using two dynamical flavours of domain wall fermions. Our analysis is based on three ensembles of configurations, each consisting of about 5,000 HMC trajectories, with a lattice spacing of approximately 1.7 GeV for 16 3 ×32 lattices; dynamical quark masses range from approximately the strange quark mass to half of that. Both degenerate and no...
متن کاملPolarised Quark Distributions from Deep Inelastic Scattering
Polarised quark distributions are extracted from semi-inclusive deep inelastic scattering data, which include the additional detection of a leading hadron to providestatisticaìàvour-tagging'. Results are combined from both proton and`neutron' targets to isolate the contributions to the nucleon spin of the individual quark avours, including the sea quarks. Spin asymmetries in the semi-inclusive ...
