A consistent light-cone-gauge superstring field theory
Yuji Ando, Ryota Fujii, Hiroshi Kunitomo +1
Extending a recent development in the bosonic string field theory, we construct a map from the Witten-type gauge-invariant superstring field theory based on an structu…

A Comment on the Higher-Spin Gauge Models
Ryota Fujii, Makoto Sakaguchi
We examine the higher-spin gauge models which are free on-shell and whose cubic vertex is BRST-exact. We show that these are free off-shell as well as on-shell. The key equation fo…

Supersymmetric Non-abelian DBI Equations from Open Pure Spinor Superstring
Ryota Fujii, Sota Hanazawa, Hiraki Kanehisa +1
The BRST invariance of the open pure spinor superstring is examined in the presence of background superfields on a Dp-brane. We note that the background superfields introduced in t…
