The differential cross-section of prompt inclusive production of long-lived charged particles in proton-proton collisions is measured using a data sample recorded by the LHCb experiment at a centre-of-mass energy of

= 13 TeV. The data sample, collected with an unbiased trigger, corresponds to an integrated luminosity of 5
