Abstract

We present a Z{sub 6} orbifold compactification of the E{sub 8}xE{sub 8} heterotic string which leads to the (supersymmetric) standard model gauge group and matter content. The quarks and leptons appear as three 16-plets of SO(10), whereas the Higgs fields do not form complete SO(10) multiplets. The model has large vacuum degeneracy. For generic vacua, no exotic states appear at low energies and the model is consistent with gauge coupling unification. The top quark Yukawa coupling arises from gauge interactions and is of the order of the gauge couplings, whereas the other Yukawa couplings are suppressed.

Gauge-Higgs Unification from the Heterotic String

Journal Article Schmidt, Jonas - AIP Conference Proceedings

We present a 6D orbifold model on T{sup 2}/Z{sub 2} which emerges as intermediate step in the compactification of the heterotic string to the supersymmetric standard model in four dimensions. It has SU(6) gauge symmetry in the bulk and two pairs of inequivalent fixed points with unbroken SU(5) and SU(2)xSU(4) symmetry, respectively. All anomalies are cancelled by the Green-Schwarz mechanism. Two quark-lepton generations are located at the SU(5) branes, the third family is composed of split bulk hypermultiplets. The model has vacua with partial or full gauge-Higgs unification and non-vanishing Yukawa couplings which generically avoid the unsuccessful SU(5) mass relations.

Seesaw Neutrinos from the Heterotic String

Journal Article Buchmueller, Wilfried ; Hamaguchi, Koichi ; Lebedev, Oleg ; ... - Physical Review Letters

We study the possibility of realizing the neutrino seesaw mechanism in the E{sub 8}xE{sub 8} heterotic string. In particular, we consider its Z{sub 6} orbifold compactifications leading to the supersymmetric standard model gauge group and matter content. We find that these models possess all the necessary ingredients for the seesaw mechanism, including the required Dirac Yukawa couplings and large Majorana mass terms. We argue that this situation is quite common in heterotic orbifolds. In contrast with the conventional seesaw of grand unified theories (GUTs), no large GUT representations are needed to generate the Majorana mass terms. The total number ofmore »« less

Statistics on the heterotic landscape: Gauge groups and cosmological constants of four-dimensional heterotic strings

Journal Article Dienes, Keith R - Physical Review. D, Particles Fields

Recent developments in string theory have reinforced the notion that the space of stable supersymmetric and nonsupersymmetric string vacua fills out a landscape whose features are largely unknown. It is then hoped that progress in extracting phenomenological predictions from string theory--such as correlations between gauge groups, matter representations, potential values of the cosmological constant, and so forth--can be achieved through statistical studies of these vacua. To date, most of the efforts in these directions have focused on type I vacua. In this note, we present the first results of a statistical study of the heterotic landscape, focusing on more thanmore »« less

Gauge coupling unification in heterotic string models with gauge mediated supersymmetry breaking

Journal Article Anandakrishnan, Archana ; Raby, Stuart - Physical Review. D, Particles Fields

We calculate the weak scale minimal supersymmetric standard model spectrum starting from a heterotic string theory compactified on an anisotropic orbifold. Supersymmetry breaking is mediated by vectorlike exotics that arise naturally in heterotic string theories. The messengers that mediate supersymmetry breaking come in incomplete grand unified theory (GUT) multiplets and give rise to nonuniversal gaugino masses at the GUT scale. Models with nonuniversal gaugino masses at the GUT scale have the attractive feature of allowing for precision gauge coupling unification at the GUT scale with negligible contributions from threshold corrections near the unification scale. The unique features of this minimallymore »« less

Minimal SUSY SO(10) and Yukawa unification

Journal Article Okada, Nobuchika - AIP Conference Proceedings

The minimal supersymmetric (SUSY) SO(10) model, where only two Higgs multiplets {l_brace}10 Circled-Plus 126-bar{r_brace} are utilized for Yukawa couplings with matter fields, can nicely fit the neutrino oscillation parameters as well as charged fermion masses and mixing angles. In the fitting of the fermion mass matrix data, the largest element in the Yukawa coupling with the 126-bar -plet Higgs (Y{sup 126}) is found to be of order one, so that the right see-saw scale should be provided by Higgs vacuum expectation values (VEVs) of {beta}(10{sup 14}GeV). This fact causes a serious problem, namely, the gauge coupling unification is spoiled becausemore »« less
