D-instanton Effects on a D3-brane
Jaroslav Scheinpflug, Yuchen Wang, Xi Yin
It has been proposed by Sen that the D-instanton effects in string theory can be systematically determined through the framework of open-closed string field theory. We apply the la…
On the Flux Sectors of Matrix String Theory
Minjae Cho, Barak Gabai, Jaroslav Scheinpflug +1
We analyze the gapped flux vacua of 2D (8,8) SU(N) super-Yang-Mills theory. Based on the matrix string theory duality, we conjecture the spectrum of massive resonances in the gauge…
On the Solution of Superstring Field Theory
Minjae Cho, João Gomide, Jaroslav Scheinpflug +1
We determine the solution of type IIB superstring field theory (SFT) to the third order in the expansion with respect to Ramond-Ramond (RR) flux, demonstrate its…
Scaffolding Residues in Yang-Mills-Scalar à la CHY
Zurab Jashi, Jaroslav Scheinpflug, Yale Yauk
Motivated by recent work by Arkani-Hamed et al. arXiv:2401.00041, we compute the ''scaffolding'' residue of -scalar Yang-Mills-Scalar amplitudes to obtain pure -gluon amplit…
The semi-chiral ring of supersymmetric theory as a representation
Jaroslav Scheinpflug
In this short note, we study the infinite-dimensional symmetry algebras which appear in holomorphic twists of 4d supersymmetric quantum field theories. In particula…
