Group-Theoretic Evidence for SO(10) Grand Unification [PDF]

, 1997
The hypercharges of the fermions are not uniquely determined in SO(10) grand unification, but rather depend upon which linear combination of the two U(1) subgroups of SO(10) > SU(3) X SU(2) X U(1) X U(1) remains unbroken.

Fermion hierarchies in SU(5) grand unification from Γ 6 ′ $$ {\Gamma}_6^{\prime } $$ modular flavor symmetry

Journal of High Energy Physics, 2023
We construct an SU(5) grand unified model in which the hierarchies of the quark and lepton masses and mixing are explained by the Γ 6 ′ $$ {\Gamma}_6^{\prime } $$ modular flavor symmetry.

Flavor unification, dark matter, proton decay and other observable predictions with low-scale $S_4$ symmetry

, 2011
We show how gauge coupling unification is successfully implemented through non-supersymmetric grand unified theory, $SO(10)\times G_f (~G_f=S_4, SO(3)_f, SU(3)_f)$, using low-scale flavor symmetric model of the type $SU(2)_L\times U(1)_Y$ $ \times SU(3 ...

Gauge unification in noncommutative geometry

, 2007
Gauge unification is widely considered to be a desirable feature for extensions of the standard model. Unfortunately the standard model itself does not exhibit a unification of its running gauge couplings but it is required by grand unified theories as ...

Grand unification in RS1 [PDF]

Annals of Physics, 2003
We study unification in the Randall-Sundrum scenario for solving the hierarchy problem, with gauge fields and fermions in the bulk. We calculate the one-loop corrected low-energy effective gauge couplings in a unified theory, broken at the scale M_GUT in the bulk.

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

FEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

The unification in an su ̂ 8 k U = 1 $$ \hat{su}{(8)}_{k_U=1} $$ affine Lie algebra

Journal of High Energy Physics
A flavor-unified theory based on the simple Lie algebra of su $$ \mathfrak{su} $$ (8) was previously proposed to generate the observed three-generational Standard Model quark/lepton mass hierarchies and the Cabibbo-Kobayashi-Maskawa mixing pattern due to

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.

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.
