"Light-Ray Operators and the BMS Algebra" by Clay Cordova (Princeton)

Tuesday, October 23, 2018 - 4:00pm to 5:00pm
TEP Seminar

Abstract:  Light-Ray Operators are non-local operators that are supported along null lines in Minkowski space.  A prominent example is the average null energy operator which has positive matrix elements in any quantum field theory.  I will discuss some basics of these operators and show that, together with light-ray versions of other Poincare generators, they satisfy a universal algebra.  This light-ray algebra contains the generalized BMS algebra which has recently played a prominent role in soft theorems.
