Canonical Gauge Coupling Unification in the Standard Model with High-Scale Supersymmetry Breaking

Yun-Jie Huo, Tianjun Li, Dimitri V. Nanopoulos

Inspired by the string landscape and the unified gauge coupling relation in the F-theory Grand Unified Theories (GUTs) and GUTs with suitable high-dimensional operators, we study t…

Super No-Scale F-SU(5): A Dynamic Determination of M_{1/2} and tan beta

Tianjun Li, James A. Maxin, Dimitri V. Nanopoulos +1

We study the Higgs potential in No-Scale F-SU(5), a model built on the tripodal foundations of the Flipped SU(5) x U(1)_X Grand Unified Theory, extra F-theory derived TeV scale vec…

The Golden Strip of Correlated Top Quark, Gaugino, and Vectorlike Mass In No-Scale, No-Parameter F-SU(5)

Tianjun Li, James A. Maxin, Dimitri V. Nanopoulos +1

We systematically establish the hyper-surface within the tan(beta), top quark mass m_t, universal gaugino mass M_1/2, and vectorlike mass M_V parameter volume which is compatible w…

Supersymmetry Breaking Scalar Masses and Trilinear Soft Terms in Generalized Minimal Supergravity

Csaba Balazs, Tianjun Li, Dimitri V. Nanopoulos +1

In the generalized minimal supergravity (GmSUGRA) scenario, we systematically study the supersymmetry breaking scalar masses, Standard Model fermion Yukawa coupling terms, and tril…

General Gauge and Anomaly Mediated Supersymmetry Breaking in Grand Unified Theories with Vector-Like Particles

Tianjun Li, Dimitri V. Nanopoulos

In Grand Unified Theories (GUTs) from orbifold and various string constructions the generic vector-like particles do not need to form complete SU(5) or SO(10) representations. To r…

Dark Matter, Proton Decay and Other Phenomenological Constraints in -SU(5)

Tianjun Li, James A. Maxin, Dimitri V. Nanopoulos +1

We study gravity mediated supersymmetry breaking in -SU(5) and its low-energy supersymmetric phenomenology. The gaugino masses are not unified at the traditional grand un…

Elements of F-ast Proton Decay

Tianjun Li, Dimitri V. Nanopoulos, Joel W. Walker

Gauge coupling unification in the Minimal Supersymmetric Standard Model (MSSM) strongly suggests the existence of a Grand Unified Theory (GUT), which could be probed by the observa…

Generalizing Minimal Supergravity

Tianjun Li, Dimitri V. Nanopoulos

In Grand Unified Theories (GUTs), the Standard Model (SM) gauge couplings need not be unified at the GUT scale due to the high-dimensional operators. Considering gravity mediated s…

F-Theory Grand Unification at the Colliders

Tianjun Li, James A. Maxin, Dimitri V. Nanopoulos

We predict the exact gaugino mass relation near the electroweak scale at one loop for gravity mediated supersymmetry breaking in F-theory SU(5) and SO(10) models with U(1)_Y and U(…
