“…While E 6 and exceptional Jordan algebras are found in these models, these seem to differ from various approaches, such as E 6 GUT [32,33,140] and recent attempts to connect J 3,O to the standard model [137][138][139][177][178][179]. Instead, we find the Peirce decomposition to give bosons and fermions, rather than only fermions 3 .…”

6D spacetime with SO(3, 3) symmetry is utilized to efficiently encode three generations of matter. A graviGUT model is generalized to a class of models that all contain three generations and Higgs boson candidates. Pati-Salam, SU (5), and SO(10) grand unified theories are found when a single generation is isolated. For example, a SO(4, 2) spacetime group may be used for conformal symmetry, AdS5 → dS4, or simply broken to SO(3, 1) of Minkowski space. Another class of models finds SO(2, 2) and can give AdS3.

“…The flipped SO(10) GUT uses the algebra so 10 ⊕ u 1 [135,136]. The flipped so 10 GUT uses the entire 27 for describing fermions, which is similar to other work in this manner [137][138][139][140]. We rule out the possibility with e 8(−24) , as only 16 of the 27 degrees of freedom are fermionic, which will become more clear below.…”

“…Since it can provide Dynkin indices of irreps it is useful in obtaining renormalization group equations [20,21,22]. In model building it has been used for extensions of the Standard Model in the way of BSM models [23,24,25,26,27,28,29], grand unified models [30,31,32,33,34,35,36,37,38,39,40,41,42,43], and other applications including SUSY models [44,45,46], supergravity models [47] and general particle physics models [48,49]. In UV completions of particle physics models, LieART has found uses in string theory [50,51], holography [52,53,54], (super-)conformal field theory [55,56,57,58,59,60,61,62,63], M-theory [64,65] and F-theory [66,…”

We present LieART 2.0 which contains substantial extensions to the Mathematica application LieART (Lie Algebras and Representation Theory) for computations frequently encountered in Lie algebras and representation theory, such as tensor product decomposition and subalgebra branching of irreducible representations. The basic procedure is unchanged-it computes root systems of Lie algebras, weight systems and several other properties of irreducible representations, but new features and procedures have been included to allow the extensions to be seamless. The new version of LieART continues to be user friendly. New extended tables of properties, tensor products and branching rules of irreducible representations are included in the appendix for use without Mathematica software. LieART 2.0 now includes the branching rules to special subalgebras for all classical and exceptional Lie algebras up to and including rank 15.

“…The anomaly cancellation can be highly non-trivial and for this reason it is theoretically interesting to consider gauge groups that are generation-independent such as the U (1) d−u group that arises after spontaneous symmetry breaking in some E 6 constructions [63]. The E 6 symmetry is theoretically motivated because it offers a hospital environment for unification of forces and incorporates interesting features of SU (5) or SO (10) groups concerning the generation of fermion masses and flavor symmetries [68][69][70][71][72][73][74], super heavy dark matter [75], and collider physics [72].…”

XENON1T takes a razor to a dark E6-inspired model

2018

View full text Add to dashboard Cite

Motivated by the recent result of XENON1T collaboration with full exposure, 279 life days, that sets the most stringent limit on the spin-independent dark matter-nucleon scattering cross section we discuss a dark E6-inspired model that features the presence of a U (1) d−u gauge symmetry. The dark matter candidate is a Dirac fermion that interacts with Standard Model fermions via a massive Z that preserves the quantum number assignments of this symmetry. We compute the spin-independent scattering cross section off xenon nucleus and compare with the XENON1T limit; find the LHC bound on the Z mass as well as the projection sensitivity of high-energy and luminosity LHC; and derive the Fermi-LAT bounds on the dark matter annihilation cross section based on the observation of gamma-rays in the direction of Dwarf Spheroidal galaxies. We exploit the complementarity between these datasets to conclude that the new bound from XENON1T severely constrain the model, which combined with the LHC upgrade sensitivity rules out this WIMP realization setup below 5 TeV.
