摘要
We propose and analyse a GUT-inspired version of the MSSM featuring non universal sfermion masses boundary conditions and asymptotic b-tau Yukawa coupling unification. The particle spectrum of the model gives rise to extended coannihilation processes, involving the lightest sbottom and the tau sneutrino. We study the allowed parameter space, subject to cosmo-phenomenological requirements, and the details of the new coannihilation modes. Implications for direct and indirect neutralino searches, as well as for collider physics, are also briefly summarized.
