LP99
XIX International Symposium on Lepton and Photon Interactions at High Energies: Stanford University August 9-14, 1999

Results for the Symposium

• LP99 asks that papers submitted to the symposium reside in the hep-ex preprint server. It is not the policy of the H1 experiment to submit results to this server until they are about to be submitted for journal publication. Therefore H1 papers of importance for LP99 are available through links on this WWW page, and are not available on hep-ex unless they have been submitted for journal publication.
• Results included here have become available either as journal publications, preprints, or contributed conference papers since LP97 (July 1997). Therefore this page includes published results and preliminary results. The latter are documented in submissions to EPS99, to ICHEP98, or to EPS97. No preliminary result is submitted to more than one year of international summer conferences.

For the purpose of conference talks and proceedings you can also find H1 results using the H1 Physics Navigator.

You can also jump straight to H1 publications.
