Measurement of the average very forward energy as a function of the track multiplicity at central pseudorapidities in proton-proton collisions at √s=13TeV
Abstract
The average total energy as well as its hadronic and electromagnetic components are measured with the CMS detector at pseudorapidities −6.6<η<−5.2 in proton-proton collisions at a centre-of-mass energy s√=13TeV. The results are presented as a function of the charged particle multiplicity in the region |η|<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. Show more
