Abstract (data abstract)
Inclusive differential production cross section of forward neutrons (and antineutrons) produced in p-p collisions at $\mathrm{\sqrt{s} = 13\,TeV}$. Cross section is expressed as a function of energy in three different pseudorapidity regions, namely $\eta > 10.76$, $8.99 < \eta < 9.22$ and $8.81 < \eta < 8.99$. The measurements refer to all neutrons (and antineutrons) directly produced in the collisions or resulting from the decay of short life particles ($\mathrm{c \tau<1\,cm}$).
