摘要
We show that in the CMSSM with the non-holomorphic soft SUSY breaking terms, the Yukawa coupling unification of the third family fermions at the GUT scale, called t - b - tau Yukawa unification (YU), is possible under the recent collider and Dark Matter results. The YU parameter can also be found R-tb tau approximate to 1, called perfect unification. We find that the squark masses exceed 3 TeV while the stau can be considerably lighter. In the case of YU, the tan beta is in the interval [46,55]. We obtain bino-like dark matter (DM) of mass in the range of 0.6 TeV less than or similar to m chi 10 less than or similar to 1.3 TeV where the recent Dark Matter direct detection limits are also satisfied. We also identify A-resonance solutions which reduce the relic abundance of LSP neutralino down to the ranges compatible with the current Planck measurements.
