The complete tables of Clebsch–Gordan (CG) coefficients for a wide class of SO(10) SUSY grand unified theories (GUTs) are given. Explicit expressions of states of all corresponding multiplets under…

Abstract.We give an explicit formula for the proton decay rate in the minimal renormalizable supersymmetric (SUSY) SO(10) model. In this model, the Higgs fields consist of the 10 and…
New realizations of Lie algebra kappa-deformed Euclidean space
- S. Meljanac, M. Stojić
- Mathematics
- 13 May 2006
We study Lie algebra κ-deformed Euclidean space with undeformed rotation algebra SOa(n) and commuting vectorlike derivatives. Infinitely many realizations in terms of commuting coordinates are…
κ-Minkowski spacetime and the star product realizations

- Mathematics
- 17 May 2007
We investigate a Lie algebra-type κ-deformed Minkowski spacetime with undeformed Lorentz algebra and mutually commutative vector-like Dirac derivatives. There are infinitely many realizations of…

Representations of non-commutative quantum mechanics and symmetries
- L. Jonke, S. Meljanac
- Physics, Mathematics
- 4 October 2002
Abstract.We present a unified approach to representations of quantum mechanics on non-commutative spaces with general constant commutators of the phase-space variables. We find two phases and duality…
Scalar field theory on noncommutative Snyder spacetime
- M. Battisti, S. Meljanac
- Mathematics
- 10 March 2010
We construct a scalar field theory on the Snyder noncommutative space-time. The symmetry underlying the Snyder geometry is deformed at the co-algebraic level only, while its Poincare algebra is…
Covariant realizations of kappa-deformed space
- S. Meljanac, S. Krešić–Jurić, M. Stojić
- Mathematics
- 27 February 2007
We study a Lie algebra type κ-deformed space with an undeformed rotation algebra and commutative vector-like Dirac derivatives in a covariant way. The space deformation depends on an arbitrary…
Modification of Heisenberg uncertainty relations in noncommutative Snyder space-time geometry
- M. Battisti, S. Meljanac
- Mathematics
- 19 December 2008
We show that the Euclidean Snyder noncommutative space implies infinitely many different physical predictions. The distinct frameworks are specified by generalized uncertainty relations underlying…
Harmonic oscillator with minimal length uncertainty relations and ladder operators
- I. Dadic, L. Jonke, S. Meljanac
- Physics
- 28 October 2002
We construct creation and annihilation operators for harmonic oscillators with minimal length uncertainty relations. We discuss a possible generalization to a large class of deformations of…
