Long strings and chiral primaries in the hybrid formalism
Lorenz Eberhardt, Kevin Ferreira
We revisit two related phenomena in string theory backgrounds. At pure NS-NS flux, the spectrum contains a continuum of long strings which can escape to the bounda…
The plane-wave spectrum from the worldsheet
Lorenz Eberhardt, Kevin Ferreira
We study string theory on backgrounds with mixed flux using the hybrid formalism of Berkovits, Vafa and Witten. We solve the worldsheet description of the theory c…
Higher spins on AdS from the worldsheet
Kevin Ferreira, Matthias R. Gaberdiel, Juan I. Jottar
It was recently shown that the CFT dual of string theory on , the symmetric orbifold of , contains a closed higher spin subsector. Via…
Even spin holography
Kevin Ferreira
A two-dimensional Sp() vector model with small superconformal symmetry is formulated, and its chiral algebra is shown to be generated by superprimary fields of…
The -Kazama-Suzuki Models at Large Level
Kevin Ferreira, Matthias R. Gaberdiel
The large level limit of the Kazama-Suzuki coset models is argued to be equivalent to the orbifold of free fermions and bosons by the Lie group…
