[NT / RIKEN seminar] Measuring color memory in a color glass condensate -- Attention:TIME AND DATE CHANGED, FEB 28th, 4pm

In the past couple of years it was shown that the low energy dynamics of gravity and gauge theories are governed by a triangular equivalence between asymptotic symmetries, soft theorems and memory effects. The conservation laws associated with the infinite-dimensional symmetries lead to soft theorems which in turn can be shown to compute transitions among an infinite number of degenerate vacua and are measured by the memory effect. 

In this talk I will introduce the color memory effect, the non-abelian gauge theory analog of gravitational memory. I will show that the passage of color radiation induces a relative $SU(3)$ color rotation of a pair of nearby quarks and argue that this effect can be measured in the Regge limit of deeply inelastic scattering experiments.
