Abstract (data abstract)
Measurement of the energy flow, the cross section and the average inelasticity of forward neutrons (+ antineutrons) produced in $\mathrm{\sqrt{s} = 13\,TeV}$ proton-proton collisions. These quantities are derived from the inclusive differential production cross section measured, as a function of energy, in the six pseudorapidity regions corresponding to $\eta > 10.75$, $10.06 < \eta < 10.75$, $9.65 < \eta < 10.06$, $8.99 < \eta < 9.21$, $8.80 < \eta < 8.99$ and $8.65 < \eta < 8.80$. The measurements refer to all neutrons (and antineutrons) directly produced in the collisions or resulting from the decay of short life particles ($\mathrm{c \tau<1\,cm}$).
