Detecting Fourth Generation Quarks at Hadron Colliders
David Atwood, Sudhir Kumar Gupta, Amarjit Soni
We consider the phenomenology of the fourth generation heavy quarks which would be pair produced at the LHC. We show that if such a quark with a mass in the phenomenologically inte…
Generalized Froggatt-Nielsen Mechanism
Fei Wang
In this paper, we propose a Generalized Froggatt-Nielsen mechanism in which non-renormalizable operators involving a GUT group and non-singlet Higgs field are introduced.…
Supersymmetry Breaking Scalar Masses and Trilinear Soft Terms From High-Dimensional Operators in E_6 SUSY GUT
Fei Wang
In the GmSUGRA scenario with the high-dimensional operators containing the GUT Higgs fields, we systematically studied the supersymmetry breaking scalar masses, SM fermion Yukawa c…
Realistic Standard Model Fermion Mass Relations in Generalized Minimal Supergravity (GmSUGRA)
Csaba Balazs, Tianjun Li, Dimitri V. Nanopoulos +1
Grand Unified Theories (GUTs) usually predict wrong Standard Model (SM) fermion mass relation m_e/m_μ = m_d/m_s toward low energies. To solve this problem, we consider the Generali…
