Superspin chains from superstring theory
Published 2022-10-01“…The latter configurations embed the superspin chains into superstring theory. We also provide a string theory derivation of a similar correspondence, proposed by Nekrasov, for rational gl(m|n) spin chains with spins valued in finite-dimensional representations.…”

More about picture-changed vertices in superstring theory
Published 1991“…We construct explicitly the lowest picture-changed vertex operators in superstring theory. We show, in particular, that the terms with (b, c) ghost number q=1 are of the form c(z) V(z) as the vertex operators in the bosonic string case.…”

Modular forms and SL(2, ℤ)-covariance of type IIB superstring theory
Published 2019-06-01“…Abstract The local higher-derivative interactions that enter into the low-energy expansion of the effective action of type IIB superstring theory with constant complex modulus generally violate the U(1) R-symmetry of IIB supergravity by q U units. …”

Modular invariance in superstring theory from N $$ \mathcal{N} $$ = 4 super-Yang-Mills
Published 2020-11-01“…Abstract We study the four-point function of the lowest-lying half-BPS operators in the N $$ \mathcal{N} $$ = 4 SU(N) super-Yang-Mills theory and its relation to the flat-space four-graviton amplitude in type IIB superstring theory. We work in a large-N expansion in which the complexified Yang-Mills coupling τ is fixed. …”
