Mass bounds on heavy-quark partners frommLmS of the K0-mesons

  • E. H. Lemke
Note Brevi


The mass differencemLmS constrains heavy-quark masses. The bounds are extended into the region abovemW½. We find a lowermU bound of 7 TeV for the scenariomCmU. Effects that could change this result are examined. Values ofmU smaller thanmW½ seem to be excluded. The applied methods and obtained results should help to shed more light on the issue of indirectCP violation.
