Phenomenological implications of light stop and higgsinos

We examine the phenomenological implications of light \tilde{t}_R and higgsinos in the Minimal Supersymmetric Standard Model, assuming \tan^2 \beta < m_t / m_b and heavy \tilde{t}_L and gauginos. In this simplified setting, we study the contributions to \Delta m_{B_d}, \epsilon_K, BR(b \rightarro...

description We examine the phenomenological implications of light \tilde{t}_R and higgsinos in the Minimal Supersymmetric Standard Model, assuming \tan^2 \beta < m_t / m_b and heavy \tilde{t}_L and gauginos. In this simplified setting, we study the contributions to \Delta m_{B_d}, \epsilon_K, BR(b \rightarrow s \gamma), R_b \equiv \Gamma (Z \rightarrow b \overline{b}) / \Gamma ( Z \to {\rm hadrons}), BR(t \to b W), and their interplay.
