Entanglement in Elastic and Inelastic Two-particle Scatterings at High Energy
Robi Peschanski, Shigenori Seki
We study the entanglement produced in transverse momentum by two-particle scattering at high energy. Employing the S-matrix framework for the derivation of reduced density matrices…
The Veneziano Amplitude via Mostly BRST Exact Operator
Isao Kishimoto, Tomoko Sasaki, Shigenori Seki +1
The Veneziano amplitude is derived from fixing one degree of freedom of symmetry by the insertion of a mostly BRST exact operator. Evaluating the five-point fun…
Reduction of Open String Amplitudes by Mostly BRST Exact Operators
Shigenori Seki, Tomohiko Takahashi
We study two and three-point tree-level amplitudes of open strings. These amplitudes are reduced from higher-point correlation functions by using mostly BRST exact operators for ga…
Two-point String Amplitudes Revisited by Operator Formalism
Shigenori Seki, Tomohiko Takahashi
So far we have considered that a two-point string amplitude vanishes due to the infinite volume of residual gauge symmetry. However recently Erbin-Maldacena-Skliros have suggested…
Evaluation of Entanglement Entropy in High Energy Elastic Scattering
Robi Peschanski, Shigenori Seki
Entanglement of the two scattered particles is expected to occur in elastic collisions, even at high energy where they are in competition with inelastic ones. We study how to evalu…
Entanglement Entropy of Scattering Particles
Robi Peschanski, Shigenori Seki
We study the entanglement entropy between the two outgoing particles in an elastic scattering process. It is formulated within an S-matrix formalism using the partial wave expansio…
