Exceptional field theories, superparticles in an enlarged 11D superspace and higher spin theories

Abstract: Recently proposed exceptional field theories (EFTs) making manifest the duality E n(n) symmetry, first observed as nonlinearly realized symmetries of the maximal d = 3, 4, ..., 9 supergravity (n = 11 − d) and containing 11D and type IIB supergravity as sectors, were formulated in enlarged spacetimes. In the case of E 7(7) EFT such an enlarged spacetime can be identified with the bosonic body of the d = 4 central charge superspace Σ (60|32) , the N = 8 d = 4 superspace completed by 56 additional bosonic coordin… Show more

“…This similarity can be relevant for higher-spin extensions of these theories, provided the section conditions can be properly relaxed (see e.g., [133,134] for a discussion of this point). It would be interesting to further elaborate on this issue, as a connection to the E 11 framework [18].…”

“…By using the obtained η-symbols, the section condition η IJ; I ∂ I ⊗ ∂ J = 0 can be expressed as follows (see [22] for a quite similar section condition and also [25] for a section condition in the "underlying EFT"):…”

“…Under the section condition, all fields can depend on at most d coordinates (see [24] for a proof in the E 7(7) EFT).In the above conventional formulation, the Y -tensor and the section condition strongly depend on the dimension d, and when we consider applications of the E d(d) EFT, we need to specify the dimension d explicitly. A hypothetical "underlying EFT" (or 11D EFT), which reproduces all E d(d) EFTs (d ≤ 8) from simple truncations, has been proposed in [25], but the program has not been completed yet. In this paper, we investigate such uniform formulations from a different approach.…”

“…The Kaluza-Klein (KK) compactifications of 11d supergravity on n-tori have a rich space of scalar moduli fields invariant under ever larger exceptional Lie groups as n increases [CJ79], reflecting just the expected duality symmetries acting on the corresponding string theories [HT95]. This led to the proposal [Hul07] (see also [KNS00][We03][PW08][We11] [Ba17]) that M-theory is an enhancement of D = 11 supergravity to a theory of "exceptional geometry" with a "generalized tangent bundle" of the form T ex X n exceptional tangent bundle := T X n ⊕ ∧ 2 X T * X n M2 wrapping modes ⊕ ∧ 5 X T * X n M5 wrapping modes ⊕ · · · (1) locally encoding wrapping modes of the M2-and the M5-brane already before KK-compactification.…”
