Abstract

Measurements of a weighted energy density average taken in the vacuum state of a conformal field theory in 1+1 dimensions are randomly distributed with vanishing expectation value. The probability distribution is computed in closed form for two infinite families of averaging functions, generalising previously known examples. These examples may be further generalised by restriction to a half-line In all cases the distribution is that of a shifted Gamma distribution.
