A measurement of the energy density in proton-proton collisions at a centre-of-mass energy of s√=13s=13 TeVTeV is presented. The data have been recorded with the CMS experiment at the LHC during low luminosity operations in 2015. The energy density is studied as a function of pseudorapidity in the ranges −6.6<η<−5.2−6.6<η<−5.2 and 3.15<|η|<5.203.15<|η|<5.20. The results are compared with the predictions of several models. All the models considered suggest a different shape of the pseudorapidity dependence compared to that observed in the data. A comparison with LHC proton-proton collision data at s√=0.9s=0.9 and 7TeV7TeV confirms the compatibility of the data with the hypothesis of limiting fragmentation.
