Correlation Functions Involving Dirac Fields from Homotopy Algebras I: The Free Theory
Keisuke Konosu, Yuji Okawa
We extend the formula for correlation functions of scalar field theories in terms of quantum algebras, presented in arXiv:2203.05366, to incorporate Dirac fields. We u…
Closed string field theory without the level-matching condition
Yuji Okawa, Ryosuke Sakaguchi
In formulating covariant closed string field theories, we have always used closed string fields with the level-matching condition. Recently, open superstring field theories includi…
Correlation functions of scalar field theories from homotopy algebras
Yuji Okawa
We present expressions for correlation functions of scalar field theories in perturbation theory using quantum algebras. Our expressions are highly explicit and can be u…
Gauge-invariant operators of open bosonic string field theory in the low-energy limit
Daiki Koyama, Yuji Okawa, Nanami Suzuki
In the AdS/CFT correspondence we consider correlation functions of gauge-invariant operators on the gauge theory side, which we obtain in the low-energy limit of the open string se…
Nonperturbative definition of closed string theory via open string field theory
Yuji Okawa
In typical examples of the AdS/CFT correspondence, the world-sheet theory with holes in the presence of D-branes is assumed to be equivalent in a low-energy limit to a world-sheet…
Open superstring field theory based on the supermoduli space
Kantaro Ohmori, Yuji Okawa
We present a new approach to formulating open superstring field theory based on the covering of the supermoduli space of super-Riemann surfaces and explicitly construct a gauge-inv…
