Kac-Moody Spectrum of (Half-)Maximal Supergravities
Eric Bergshoeff, Joaquim Gomis, Teake Nutma +1
We establish the correspondence between, on one side, the possible gaugings and massive deformations of half-maximal supergravity coupled to vector multiplets and, on the other sid…
Stringy cosmic strings in matter coupled N=2, d=4 supergravity
Eric A. Bergshoeff, Jelle Hartong, Mechthild Hübscher +1
We extend the system of ungauged N=2, d=4 supergravity coupled to vector multiplets and hypermultiplets with 2-form potentials. The maximal number of 2-form potentials that one may…
Q7-branes and their coupling to IIB supergravity
Eric Bergshoeff, Jelle Hartong, Dmitri Sorokin
We show how, by making use of a new basis of the IIB supergravity axion-dilaton coset, SL(2,R)/SO(2), 7-branes that belong to different conjugacy classes of the duality group SL(2,…
