Explore the extension of Kawai-Lewellen-Tye (KLT) relations from flat space to Anti-de Sitter (AdS) spacetime in this high-energy physics seminar. Learn how the fundamental building blocks of tree-level open- and closed-string amplitudes function in AdS geometry and discover their interconnections through an AdS version of the KLT relations. Examine how string theory reveals hidden structures connecting different theoretical frameworks, from the original closed-string amplitudes expressed as quadratic combinations of open-string amplitudes to the celebrated double-copy relationship between gluons and gravitons in field theory limits. Understand how this elegant mathematical structure persists when transitioning from flat spacetime to curved AdS backgrounds, and investigate how these relationships not only simplify explicit calculations but also point toward deeper algebraic and geometric structures awaiting further exploration in theoretical physics.
