| Version | The Q2 evolution of F2 for three active flavours compared to the asymptotic solution and the QPM prediction. |
| PhysRep | The original figure. |
| 05/10/00 | The new published OPAL measurements from CERN-EP/2000-082 as well as a new preliminary OPAL measurement at 709 GeV2 have been included. The numbers from CERN-EP/2000-082 partly replace older OPAL results. In addition, the layout of the figure has been slightly changed. |
| 08/11/00 | The preliminary DELPHI measurements from TabD12 have been replaced by the recent preliminary numbers presented by I. Tiapkin at the PHOTON2001 conference. In addition, the preliminary OPAL measurement at Q2 = 706 GeV2 has been replaced by the recent preliminary numbers at Q2 = 767 GeV2 from the OPAL Physics Note 489. Also a bug in the calculation of the QPM prediction has been removed. |
| 09/07/03 |
The old preliminary measurements from ALEPH at Q2 = 13.7 and 56.5 GeV2 have been replaced by the recent results from CERN-EP-2003-033 given at Q2 = 17.3 and 67.2 GeV2. The old preliminary DELPHI measurements have been removed. New DELPHI results are included. They are taken from CERN-EP-2003-018 abailable from the Delphi Publication page. Only the numbers obtained using LEP1 data and quoted at Q2 = 5.2, 12.7 and 28.5 GeV2 have been incuded. The results obtained using LEP2 data are not included. This is because the most significant error, stemming from the model dependence when using different MC models to obtain the structure function are not included in the quoted result. If so, then in many cases they would dominate the error, and therefore I refrained from adding this error myself. The preliminary OPAL measurement at Q2 = 767 GeV2 has been replaced by the published result at Q2 = 780 GeV2 from CERN-EP-2002-014. In addition, to better identify the version of the plot, the date of production has been added. |
