Testing theSU(3)L ×U(1) X model from muonium → antimuonium conversion

  • Pyungwon Ko
Note Brevi


Dilepton gauge bosons (Y) in theSU(3)L×U(1) X model can generate muonium → antimuonium conversion. Since theSU(3)L×U(1) X model requiresMY<350 GeV, it predicts the conversion probability to beP\(\bar M\)>5.3·10−8. Thus, this model can be easily tested by improving the current upper limit on the muonium → antimuonium conversion probability by an order of magnitude.
