TL;DR: The superstring flipped SU (5) model remains intact after the inclusion in the superpotential of the low-energy effective theory of all relevant string-induced non-renormalizable terms as discussed by the authors.

TL;DR: In this paper, a basic theorem on the decomposition of SO(2 N ) vertices is used to obtain a complete analytic determination of all SO(10)-invariant cubic superpotential couplings involving 16 ± semispinors of SO (10) chirality ± and tensor representations.

TL;DR: In this paper, the intersecting brane configuration of type IIA string theory corresponding to the meta-stable nonsupersymmetric vacua in four-dimensional supersymmetric SU(Nc) gauge theory with an antisymmetric flavor, a conjugate symmetric flavour, eight fundamental flavours, mf fundamental flavours and mf antifundamental flavors was described.
Abstract: We describe the intersecting brane configuration of type IIA string theory corresponding to the meta-stable nonsupersymmetric vacua in four-dimensional supersymmetric SU(Nc) gauge theory with an antisymmetric flavour, a conjugate symmetric flavour, eight fundamental flavours, mf fundamental flavours and mf antifundamental flavours. This is done by analysing the supersymmetric SU(2mf − Nc + 4) magnetic gauge theory with dual matters and the corresponding dual superpotential.

TL;DR: In this article, a supersymmetric Yang-Mills theory in four dimensions with gauge group SU(3N) was studied, where the gauge group is spontaneously broken further to the low-energy gauge groups SU(4)×SU(2)× SU(2), SU( 4)3 and SU( 3)3.
Abstract: Starting with a $ \mathcal{N} = 4 $
supersymmetric Yang-Mills theory in four dimensions with gauge group SU(3N) we perform an orbifold projection leading to a $ \mathcal{N} = 1 $
supersymmetric SU(N)3 Yang-Mills theory with matter supermultiplets in bifundamental representations of the gauge group, which is chiral and anomaly free. Subsequently, we search for vacua of the projected theory which can be interpreted as spontaneously generated twisted fuzzy spheres. We show that by adding the appropriate soft supersymmetry breaking terms we can indeed reveal such vacua. Three cases are studied, where the gauge group is spontaneously broken further to the low-energy gauge groups SU(4)×SU(2)×SU(2), SU(4)3 and SU(3)3. Such models behave in intermediate scales as higher-dimensional theories with a finite Kaluza-Klein tower, while their low-energy physics is governed by the corresponding zero-modes and exhibit chirality in the fermionic sector. The most interesting case from the phenomenological point of view turns out to be the SU(3)3 unified theory, which has several interesting features such as (i) it can be promoted to a finite theory, (ii) it breaks further spontaneously first to the MSSM and then to SU(3)×U(1)

due to its own scalar sector, i.e. without the need of additional superfields and (iii) the corresponding vacua lead to spontaneously generated fuzzy spheres.
