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…
