Key Words: Confinement in Gauge Theories, AdS/CFT, Conformal Bootstrap
Abstract: I will discuss the confinement problem for gauge theories in rigid AdS background, and its formulation in terms of boundary conditions, focussing on pure Yang-Mills theory and QCD with fundamental matter. In this formulation an important role is played by the conformal correlators at the boundary of AdS. The Dirichlet boundary condition for the gauge field is conjectured to disappear via merger and annihilation, as signaled by the lightest scalar singlet operator approaching marginality as the coupling increases. I will explain how to test this and similar scenarios (higgsing and decoupling) using both perturbative calculations and non-perturbative constraints from the numerical conformal bootstrap.

Key Words: Effective Field Theories, Scattering Amplitudes, S-matrix Bootstrap
Abstract: In these lectures I will give an overview of the non-perturbative S-matrix bootstrap program. First I will focus on gapped systems, discussing basic concepts, such as dispersion relations and unitarity constraints, and explaining what we can learn by asking bootstrap questions. Then I will consider gapless scattering, such as goldstones and gravitons, and explain how unitarity constraints relax into positivity bounds and how the two are connected to each other. As a part of these lectures I will review what news we have learned about experimental data, and strongly coupled theories, from Analyticity, Crossing, and Unitarity.
