Supersymmetry Breaking and Dilaton Stabilization in String Gas Cosmology

open access: yes, 2011
In this Note we study supersymmetry breaking via gaugino condensation in string gas cosmology. We show that the same gaugino condensate which is introduced to stabilize the dilaton breaks supersymmetry.

Notes on Characterizations of 2d Rational SCFTs: Algebraicity, Mirror Symmetry, and Complex Multiplication

open access: yesFortschritte der Physik, Volume 73, Issue 1-2, February 2025.
Abstract S. Gukov and C. Vafa proposed a characterization of rational N=(1,1)$N=(1,1)$ superconformal field theories (SCFTs) in 1+1$1+1$ dimensions with Ricci‐flat Kähler target spaces in terms of the Hodge structure of the target space, extending an earlier observation by G. Moore.

Stealth supersymmetry [PDF]

open access: yesJournal of High Energy Physics, 2011
We present a broad class of supersymmetric models that preserve R-parity but lack missing energy signatures. These models have new light particles with weak-scale supersymmetric masses that feel SUSY breaking only through couplings to the MSSM. This small SUSY breaking leads to nearly degenerate fermion/boson pairs, with small mass splittings and hence

T‐Symmetry in String Geometry Theory

open access: yesAdvances in High Energy Physics, Volume 2025, Issue 1, 2025.
String geometry theory is one of the candidates of nonperturbative formulation of string theory. In this paper, we have shown that dimensionally reduced string geometry theories have what we call T‐symmetry. In the case of the dimensional reduction in space‐like directions, the T‐symmetry transformation gives the T‐dual transformation between the Type ...

Constraining supersymmetry [PDF]

open access: yesNew Journal of Physics, 2002
We review constraints on the minimal supersymmetric extension of the Standard Model (MSSM) coming from direct searches at accelerators such as LEP, indirect measurements such as b -> s gamma decay and the anomalous magnetic moment of the muon. The recently corrected sign of pole light-by-light scattering contributions to the latter is taken into ...

Supersymmetric Extension of Non-Hermitian su(2) Hamiltonian and Supercoherent States

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2010
A new class of non-Hermitian Hamiltonians with real spectrum, which are written as a real linear combination of su(2) generators in the form H=ωJ_3+αJ_−+βJ_+, α≠β, is analyzed.

Adinkras for Mathematicians [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2013
$\textit{Adinkras}$ are graphical tools created for the study of supersymmetry representations. Besides having inherent interest for physicists, the study of adinkras has already shown connections with coding theory and Clifford algebras.

IS (Low Energy) SUSY STILL ALIVE?

open access: yes, 2012
Supersymmetry, a new symmetry that relates bosons and fermions in particle physics, still escapes observation. Search for supersymmetry is one of the main aims of the Large Hadron Collider.

(O)Mega Split [PDF]

open access: yes, 2015
We study two realisations of the Fake Split Supersymmetry Model (FSSM), the simplest model that can easily reproduce the experimental value of the Higgs mass for an arbitrarily high supersymmetry scale, as a consequence of swapping higgsinos for ...

Supersymmetric unification without low energy supersymmetry and signatures for fine-tuning at the LHC [PDF]

open access: yes, 2004
The cosmological constant problem is a failure of naturalness and suggests that a fine-tuning mechanism is at work, which may also address the hierarchy problem. An example — supported by Weinberg's successful prediction of the cosmological constant — is
