    • General F-theory models with tuned (SU(3) × SU(2) × U(1))/ℤ6 symmetry 

      Raghuram, Nikhil; Taylor, Washington; Turner, Andrew P. (2020-04-01)
      We construct a general form for an F-theory Weierstrass model over a general base giving a 6D or 4D supergravity theory with gauge group (SU(3) × SU(2) × U(1))/ℤ6 and generic associated matter, which includes the matter ...
    • Large U(1) charges in F-theory 

      Raghuram, Nikhil; Taylor, Washington (Springer, 2018-10-29)
      We show that massless fields with large abelian charges (up to at least q = 21) can be constructed in 6D F-theory models with a U(1) gauge group. To show this, we explicitly construct F-theory Weierstrass models with ...
    • Matter in transition 

      Anderson, Lara B.; Gray, James; Raghuram, Nikhil; Taylor, Washington (Springer, 2016-04-13)
      We explore a novel type of transition in certain 6D and 4D quantum field theories, in which the matter content of the theory changes while the gauge group and other parts of the spectrum remain invariant. Such transitions ...
