Abstract

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 tbτ t-b-\tau Yukawa unification (YU), is possible under the recent collider and Dark Matter results. The YU parameter can also be found Rtbτ1 R_{tb\tau} \approx 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 tanβ \tan\beta is in the interval [46,55] [46,55] . We obtain bino-like dark matter (DM) of mass in the range of 0.6 0.6 TeV mχ101.3 \lesssim m_{\chi_{1}^{0}} \lesssim 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.
