A DETERMINATION OF THE FRAGMENTATION FUNCTIONS OF u QUARKS INTO CHARGED PIONS

The European Muon collaboration Aubert, J.J. ; Bassompierre, G. ; Becks, K.H. ; et al.
Phys.Lett.B 160 (1985) 417-420, 1985.
Inspire Record 213987 DOI 10.17182/hepdata.49627

The fragmentation functions of u-quarks into positive and negative pions are determined from an analysis of identified pions produced in deep inelastic muon-deuterium scattering. The method adopted is not sensitive to the knowledge of the primary quark distribution functions. The fragmentation of u quarks to positive pions is found to fall less steeply in z than that to negative pions as expected in the quark parton model.

$D^{*\pm}$ Production in Jets at the {CERN} {SPS} Collider

The UA1 collaboration Arnison, G. ; Allkofer, O.C. ; Astbury, A. ; et al.
Phys.Lett.B 147 (1984) 222-226, 1984.

We report evidence for the production of the charged D ∗ mesons in pp̄ collisions at s = 540 GeV . The search was confined to the charged particle fragments of hadronic jets, which are expected to be predominantly gluon jets in this experiment. The fragmentation function and production rate for D ∗ in jets of average transverse momentum of 28 GeV/ c are given.

THE D*'S ARE CONSIDERED AS ARISING ONLY FROM FRAGMENTATION OF HADRONIC JETS ('GLUON' JETS). HERE THE <PT> OF THE JET IS AROUND 28 GEV THE DEFINITION OF Z IS P(D*).P(JET)/(P(JET))**2.


FRAGMENTATION IN NEUTRINO AND ANTI-NEUTRINOS CHARGED CURRENT INTERACTIONS ON PROTON AND NEUTRON

The AMSTERDAM-BERGEN-BOLOGNA-PADUA-PISA-SACLAY-TURIN collaboration Allasia, D. ; Angelini, C. ; Baldini, A. ; et al.
Z.Phys.C 24 (1984) 119-131, 1984.
Inspire Record 207322 DOI 10.17182/hepdata.16217

Some experimental properties of the charged hadronic fragments are compared for νp, νn,\(\bar vp\) and\(\bar vn\) interactions: multiplicities of forward and backward going particles,xF distributions for pions, fragmentation functions and theirQ2 andW2 dependence. The results are compared with the predictions of the Lund fragmentation model.
