Abstract: (Springer)

The average total energy as well as its hadronic and electromagnetic components are measured with the CMS detector at pseudorapidities

-6.6<\eta <-5.2

in proton-proton collisions at a centre-of-mass energy

\sqrt{s}=13\,\text {TeV}

. The results are presented as a function of the charged particle multiplicity in the region

|\eta |<2

. This measurement is sensitive to correlations induced by the underlying event structure over a very wide pseudorapidity region. The predictions of Monte Carlo event generators commonly used in collider experiments and ultra-high energy cosmic ray physics are compared to the data. All generators considered overestimate the fraction of energy going into hadrons.
