Automatic Enhancement in 6D Supergravity and F-theory Models

Nikhil Raghuram,
Washington Taylor,
Andrew P. Turner

Abstract: We observe that in many F-theory models, tuning a specific gauge group G and matter content M under certain circumstances leads to an automatic enhancement to a larger gauge group G ⊃ G and matter content M ⊃ M . We propose that this is true for any theory G, M whenever there exists a containing theory G , M that cannot be Higgsed down to G, M . We give a number of examples including non-Higgsable gauge factors, nonabelian gauge factors, abelian gauge factors, and exotic matter. In each of these cases, tuning … Show more

“…• The models involving u(1) factors in [28], including the su(18) ⊕ u(1) and su(19) ⊕ u(1) models. While these models were not analyzed using resolutions, the matter spectra given there, which can be recovered with the techniques presented here, agree with the anomaly cancellation conditions and the expectations from Higgsing related nonabelian models.…”

“…[12]) gives many insights into these theories, but at this time there are still substantial classes of apparently consistent 6D supergravity theories without an F-theory realization; for example, there is an infinite class of theories with no tensor multiplets, a single U(1) gauge factor, and matter fields with arbitrarily large U(1) charges that cannot be realized in F-theory but that satisfy anomaly cancellation and all other known quantum consistency conditions on low-energy 6D field theories coupled to gravity [13]. Other aspects of the 6D supergravity swampland have been explored in a variety of papers, including [5,10,[14][15][16][17][18][19].…”

“…In [30] related aspects of the global structure of the gauge group for 8D F-theory models have been investigated. In [18], a general characterization is given of a large set of 6D supergravity models that appear to be compatible with known quantum consistency conditions but lack an F-theory realization. Such models violate an automatic enhancement condition that seems to hold for all theories that come from F-theory.…”
