标题： Search for supersymmetric particles in light gravitino scenarios and sleptons NLSP

摘要： 在轻超对称粒子是引力子的场景中，对sleptons、neutralinos、charginos、sgoldstinos和重稳定带电sleptons的搜索结果如下。 在2000年期间，使用DELPHI探测器在质心能量从204到208 GeV的数据被分析，并与1995年至1999年在较低能量下收集的所有数据相结合。 未发现sleptons、neutralinos和charginos产生的证据，因此设定了这些超对称粒子的质量以及模型参数空间的新限制。 对重稳定带电sleptons的搜索也更新了稳定sleptons的质量限制。 未发现sgoldstino产生的证据，从而设定了其质量以及超对称破缺尺度的限制。 显示英文摘要

摘要： A search for sleptons, neutralinos, charginos, sgoldstinos and heavy stable charged sleptons in the context of scenarios where the lightest supersymmetric particle is the gravitino, is presented. Data collected during 2000 with the DELPHI detector at centre-of-mass energies from 204 to 208 GeV were analysed and combined with all the data collected from 1995 to 1999 at lower energies. No evidence for the production of sleptons, neutralinos and charginos has been found, therefore new limits on the mass of these supersymmetric particles and on the model parameter space are set. The search for heavy stable charged sleptons also updates the stable sleptons mass limit. The absence of evidence for sgoldstino production allows limits to be set on its mass and on the scale of supersymmetry breaking.
