A natural MSSM from a novel SO(10), Yukawa unification, light sparticles, and SUSY implications at LHC

Journal of High Energy Physics
The SO(10) model with a heavy Higgs spectrum consisting of 560 + 560 ¯ $$ \overline{560} $$ and a light Higgs spectrum consisting of 2 10 + 320 plet representations of SO(10) is unique among SO(10) models.

Organoids in pediatric cancer research

FEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

FEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Fermion masses and mixings in supersymmetric SO(10) with third-generation quasi-Yukawa unification

Journal of High Energy Physics
We discuss the charged and neutral fermion masses and mixings in a supersymmetric SO(10) model with a minimal Higgs sector consisting of the multiplets 10 H , 45 H , and $${16}_{H}+{\overline{16} }_{H}$$ .

Probing grand unification with quantum sensors

Physics Letters B
We discuss how grand unification can be probed with experiments at low energies using quantum sensors. Specifically, we show that scalar multiplets coupled to the gauge sector of a grand unified theory provide a mechanism for a time-varying unified ...

Asymmetric orbifolds and grand unification [PDF]

Physical Review D, 1996
We generalize the rules for the free fermionic string construction to include other asymmetric orbifolds with world-sheet bosons. We use these rules to construct various grand unified string models that involve level-3 current algebras. We present the explicit construction of three classes of 3-chiral-family grand unified models in the heterotic string

Nilpotent symmetries as a mechanism for Grand Unification

Journal of High Energy Physics, 2021
In the classic Coleman-Mandula no-go theorem which prohibits the unification of internal and spacetime symmetries, the assumption of the existence of a positive definite invariant scalar product on the Lie algebra of the internal group is essential.

Weinberg angle without grand unification [PDF]

Physical Review D, 1993
We assume that strong and electroweak interactions become strong at very high energies. With this assumption, we compute the low-energy gauge coupling constants $ _i (m_Z)$ as a function of the cutoff scale, taking the supersymmetric standard model with $3+2n$ families of quark and lepton multiplets.

Seeing higher-dimensional grand unification in primordial non-gaussianities

Journal of High Energy Physics, 2019
The observed low-energy values of the SU(3) × SU(2) × U(1) gauge couplings, extrapolated via the minimal Standard Model Renormalization Group evolution, hint at the exciting possibility of a Grand Unified Theory (GUT) at M U ∼ 1014 GeV — a scale, however,
