Maths HEP Lunchtime Seminars: Identifying physical reflection factors using the exact g-function

Presented by Anna Lishman (Durham),

13 January 2006 13:00 in CM221

"There are two ways to approach an integrable boundary QFT, namely from the UV and IR. From the UV point of view we have a perturbation of a boundary CFT, whereas in the IR there is a particle description in terms of boundary scattering matrices (reflection factors). The question is, what is the relationship between these two descriptions? I aim to show how the exact -function can be used to identify which reflection factors are physical, and give a strong indication of the boundary conditions to which they correspond. I will also describe how this method can be used to find flows between conformal boundary conditions."
