  • 1983
  • Ingår i: Physical Review Letters. - 0031-9007 .- 1079-7114. ; 51:24, s. 2179-2182

    • The possible importance of diquarks in high-energy physics is discussed and it is suggested that this nonperturbative phenomenon can explain the trends in high-energy data that are usually attributed to gluon processes as described by perturbative QCD. Several experimental tests are suggested for discriminating between gluon and diquark phenomena.

  • Clusters and tubes in multiparticle production from nuclear targets
  • 1980
  • Ingår i: Physical Review Letters. - 0031-9007 .- 1079-7114. ; 45:17, s. 1371-1374
  • Tidskriftsartikel (refereegranskat)abstract
    • Recent data on backward pion production in 0.8-4.89-GeV proton-nucleus collisions are analyzed within the scope of models where target nucleons react collectively. It is shown that the nuclear-size dependence in data is a sensitive probe of the effective target mass. The experimental results hint at a synthesis of the cluster ("fluctuon") model and the collective tube model.

  • Nuclear structure functions and the size of diquarks in nucleons
  • 1984
  • Ingår i: Physical Review Letters. - 0031-9007 .- 1079-7114. ; 52:9, s. 724-726
  • Tidskriftsartikel (refereegranskat)abstract
    • It is suggested that the observed difference between deep-inelastic structure functions from iron and deuterium targets comes about because two of the quarks in a nucleon are tightly bound in a diquark. It suffices for reproducing the data to assume that the diquark radius is enhanced by 10%-45% in a dense nucleus because of the disturbance from the surrounding nucleons. It is suggested how such a change of the diquark scale could be distinguished from the recently proposed change in the scale of the whole nucleon.

  • The diquark deuteron
  • 1982
  • Ingår i: Physical Review Letters. - 0031-9007 .- 1079-7114. ; 48:1, s. 14-16
  • Tidskriftsartikel (refereegranskat)abstract
    • It is speculated that an almost stable state of hadronic and nuclear matter can be built from diquarks. It is suggested that this alternative form of matter has already revealed itself in existing experimental data in the form of a diquark "deuteron" with JP=0- and with several other anomalous properties.

  • Time-resolved laser spectroscopy on high-lying states in neutral oxygen
  • 1985
  • Ingår i: Physical Review Letters. - 1079-7114. ; 55:3, s. 284-287
  • Tidskriftsartikel (refereegranskat)abstract
    • Radiative lifetimes have been measured for five triplet states of atomic oxygen. The oxygen atoms were generated by photodissociation of NO2 and the investigated states were populated through a two-step process involving a two-photon excitation to the lowest excited triplet state of even parity, 2p33p 3P, followed by a one-photon excitation to the investigated state. A similar scheme is applicable to the study of excited states in many light atoms.
