This conference is the focal point of all our field since more than fifty years and is the reference event where all important results in particle physics cosmology and astroparticles are presented and discussed. This alone sufficed to make this event very important. But in 2010, a coincidence of exceptional events made this conference even more attractive! What is then so special about ICHEP 2010 conference? It was the first ICHEP conference where physics results obtained at the LHC were presented! New results about the elusive Higgs boson, or signals of physics beyond the standard model were therefore expected at this conference! Major discoveries in other domains such as gravitational waves, neutrino telescopes, neutrino oscillations, dark matter or in the flavour sector were also possible, just to name a few.</p> <p><font face="Verdana, Arial, Helvetica, sans-serif" size="-2">In addition , 2010 is an important date to shape up the future of our field. Several major projects presented the status of their Conceptual or Engineering Design Reports during the conference. The International Linear Collider (ILC) Global Design Effort team presented the report corresponding to the end of their Technical Design Phase 1. The Compact Linear Collider (CLIC) also reported on its Conceptual Design Report. Other major projects such as Super B factories were also presented. These reports together with LHC physics results will form the basis for key political decisions needed to be taken in the years to come.</font></p> <p><font face="Verdana, Arial, Helvetica, sans-serif" size="-2">In summary, there can be no doubt that Paris was the place to be in summer 2010 for anyone interested in High Energy Physics and we made every effort to make your stay as interesting and enjoyable as possible.</font></p> <p>The next ICHEP conference, <a href="http://www.ichep2012.com.au/">ICHEP2012</a>, will take place in Australia.</p></td> </tr> </tbody></table> False Palais des Congrès de Paris

Salle 251 2010-07-22T14:00:00 2010-07-22T14:13:00 00:13 We report the experiment on a precise comparison of (e+ p) and (e- p) scattering cross sections, which gives a direct experimental evidence for the two-photon exchange (TPE) contribution in this reaction. Such data are in demand now, because they, most likely, may explain the dramatic disagreement of proton electromagnetic form factors measurements in the polarization transfer (PT) experiments at Jefferson Lab with previous unpolarized measurements using a Rosenbluth separation (RS) technique. Common practice of the analysis of RS experiments was in approximate taking into account of TPE contribution, believing this contribution to be small. Currently there are no accurate calculations of the TPE contribution, what is related to difficulties in accounting of the intermediate states of proton. But recent calculations, which takes particular account of proton structure, shows importance of TPE contribution for RS analysis. As far as the experimental situation, only old (in 1960th) measurements exist, where the TPE contribution were found with low precision and limited kinematics coverage. Reported experiment was performed recently at VEPP-3 storage ring at the energy of positron/electron beams 1.6 GeV and three regions of electron/positron scattering angle - around 10, 18 and 64 degrees. The smallest angle region was used for luminosity monitoring. Electron and positron beams were replaced each other regularly, one cycle with two beams required 1.5 hours. Internal hydrogen gas target had a thickness 5*10^14 at/cm2. Experiment duration was 1500 hours with a mean luminosity of 5*10^31 1/(s cm2). The preliminary results on (e+ p)/(e- p) cross sections ratio will be presented. slides doc http://indico.cern.ch/images/word.png word file ppt http://indico.cern.ch/images/powerpoint.png powerpoint file pdf http://indico.cern.ch/images/pdf_small.png pdf file odt http://indico.cern.ch/images/writer.png writer file odp http://indico.cern.ch/images/impress.png presentation file ods http://indico.cern.ch/images/calc.png spreadsheet file other http://indico.cern.ch/images/file_small.png unknown type file link http://indico.cern.ch/images/link.png link minutes doc http://indico.cern.ch/images/word.png word file ppt http://indico.cern.ch/images/powerpoint.png powerpoint file pdf http://indico.cern.ch/images/pdf_small.png pdf file odt http://indico.cern.ch/images/writer.png writer file odp http://indico.cern.ch/images/impress.png presentation file ods http://indico.cern.ch/images/calc.png spreadsheet file other http://indico.cern.ch/images/file_small.png unknown type file link http://indico.cern.ch/images/link.png link paper doc http://indico.cern.ch/images/word.png word file ppt http://indico.cern.ch/images/powerpoint.png powerpoint file pdf http://indico.cern.ch/images/pdf_small.png pdf file odt http://indico.cern.ch/images/writer.png writer file odp http://indico.cern.ch/images/impress.png presentation file ods http://indico.cern.ch/images/calc.png spreadsheet file other http://indico.cern.ch/images/file_small.png unknown type file link http://indico.cern.ch/images/link.png link yes poster doc http://indico.cern.ch/images/word.png word file ppt http://indico.cern.ch/images/powerpoint.png powerpoint file pdf http://indico.cern.ch/images/pdf_small.png pdf file odt http://indico.cern.ch/images/writer.png writer file odp http://indico.cern.ch/images/impress.png presentation file ods http://indico.cern.ch/images/calc.png spreadsheet file other http://indico.cern.ch/images/file_small.png unknown type file link http://indico.cern.ch/images/link.png link slides doc http://indico.cern.ch/images/word.png word file ppt http://indico.cern.ch/images/powerpoint.png powerpoint file pdf http://indico.cern.ch/images/pdf_small.png pdf file odt http://indico.cern.ch/images/writer.png writer file odp http://indico.cern.ch/images/impress.png presentation file ods http://indico.cern.ch/images/calc.png spreadsheet file other http://indico.cern.ch/images/file_small.png unknown type file link http://indico.cern.ch/images/link.png link 2013-05-25 2013-05-26
