Supersymmetry Breaking in the Minimal Supersymmetric Standard Model and Impact of Neutralino Dark Matter on µ Bound, Ph.D. Dissertation Sharif University of Technology ; Arfaei, Hesamaddin (Supervisor) ; Torabian, Mahdi (Supervisor)
Abstract
Supersymmetry breaking mechanism is an unanswered question. Which is not allowed to break at tree-level in MSSM due to supertrace restrictions. Most theories suppose it’s broken in a dark section, much higher energies than electro-weak and its impacts as soft SUSY breaking terms emerged in Lagrangian. Here, in a different approach, an extension of MSSM with a U(1) and Stueckelberg superfield along with nonlinear gauge transformation, provides an additional condition to present a tree-level SUSY breaking mechanism. Mass mixing term in Stueckelberg’s Lagrangian or kinetic mixing are two methods of such an extension. The particles mass terms, solving the Higgsino mass parameter problem µ,...
