On Conformal Block, Crossing Kernel and Multi-variable Hypergeometric Functions
Heng-Yu Chen, Hideki Kyono
In this note, we present an alternative representation of the conformal block with external scalars in general spacetime dimensions in terms of a finite summation over Appell fourt…
Towards Spinning Mellin Amplitudes
Heng-Yu Chen, En-Jui Kuo, Hideki Kyono
We construct the Mellin representation of four point conformal correlation function with external primary operators with arbitrary integer spacetime spins, and obtain a natural pro…
Comments on 2D dilaton gravity system with a hyperbolic dilaton potential
Hideki Kyono, Suguru Okumura, Kentaroh Yoshida
We proceed to study a (1+1)-dimensional dilaton gravity system with a hyperbolic dilaton potential. Introducing a couple of new variables leads to two copies of Liouville equations…
Anatomy of Geodesic Witten Diagrams
Heng-Yu Chen, En-Jui Kuo, Hideki Kyono
We revisit the so-called "Geodesic Witten Diagrams" (GWDs) \cite{ScalarGWD}, proposed to be the holographic dual configuration of scalar conformal partial waves, from the perspecti…
Deformations of the Almheiri-Polchinski model
Hideki Kyono, Suguru Okumura, Kentaroh Yoshida
We study deformations of the Almheiri-Polchinski (AP) model by employing the Yang-Baxter deformation technique. The general deformed AdS metric becomes a solution of a deformed…
Melnikov's method in String Theory
Yuhma Asano, Hideki Kyono, Kentaroh Yoshida
Melnikov's method is an analytical way to show the existence of classical chaos generated by a Smale horseshoe. It is a powerful technique, though its applicability is somewhat lim…
