Serre Relation and Higher Grade Generators of the AdS/CFT Yangian Symmetry
Takuya Matsumoto, Sanefumi Moriyama
It was shown that the spin chain model coming from AdS/CFT correspondence satisfies the Yangian symmetry if we assume evaluation representation, though so far there is no explicit…
Instanton Calculus and Loop Operator in Supersymmetric Gauge Theory
Hiroaki Kanno, Sanefumi Moriyama
We compute one-point function of the glueball loop operator in the maximally confining phase of supersymmetric gauge theory using instanton calculus. In the maximally confining pha…
A Secret Symmetry of the AdS/CFT S-matrix
Takuya Matsumoto, Sanefumi Moriyama, Alessandro Torrielli
We find a new quantum Yangian symmetry of the AdS/CFT S-matrix, which complements the original su(2|2) symmetry to gl(2|2) and does not have a Lie algebra analog. Our finding is mo…
A Yangian Double for the AdS/CFT Classical r-matrix
Sanefumi Moriyama, Alessandro Torrielli
We express the classical r-matrix of AdS/CFT in terms of tensor products involving an infinite family of generators, which takes a form suggestive of the universal expression obtai…
Twist Field as Three String Interaction Vertex in Light Cone String Field Theory
Isao Kishimoto, Sanefumi Moriyama, Shunsuke Teraguchi
It has been suggested that matrix string theory and light-cone string field theory are closely related. In this paper, we investigate the relation between the twist field, which re…
Boundary and Midpoint Behaviors of Lump Solutions in Vacuum String Field Theory
Hiroyuki Hata, Sanefumi Moriyama
We discuss various issues concerning the behaviors near the boundary (σ=0,π) and the midpoint (σ=π/2) of the open string coordinate X(σ) and its conjugate momentum P(σ)=-iδ/δX(σ) a…
