Conformal transformations and strings for an accelerating quark-antiquark pair in AdS 3

Abstract

From a simple moving open string solution dual to a moving heavy quark with constant velocity in the Poincare AdS 3 spacetime, we construct an accerlerating open string solution dual to a heavy quark-antiquark pair accelerated in opposite directions by performing the three mappings such as the SL(2, R) L × SL(2, R) R isometry transformation, the special conformal transformation and the conformal SO(2,2) transformation. Using the string sigma model action we construct two open string solutions staying in two different regions whose dividing line is associated with the event horizon appeared on the string worldsheet and obtain the accelerating open string solution by gluing two such solutions.
