RECENT MEASUREMENTS OF TWO PHOTON MUON PAIR PROCESS FROM MARK J

  • The recent results from Mark J on two photon muon pair production with √S from 14 to 46.78GeV are presented, and compared with the complete α4 QED calculation in a large range of √S and four momentum transfer, including untagged, single and double tagged events. The forward-backward charge asymmetry of muons produced in the two photon process in also compared to the QED prediction.

Abstract: The recent results from Mark J on two photon muon pair production with √S from 14 to 46.78GeV are presented, and compared with the complete α4 QED calculation in a large range of √S and four momentum transfer, including untagged, single and double tagged events. The forward-backward charge asymmetry of muons produced in the two photon process in also compared to the QED prediction.
