 Measurements of longitudinal and transverse momentum distributions for neutral pions in the forward-rapidity region with the LHCf detector / Adriani, O. ; Berti, E. ; Bonechi, L. ; Bongi, M. ; D’Alessandro, R. ; Del Prete, M. ; Haguenauer, M. ; Itow, Y. ; Kasahara, K. ; Kawade, K. et al. /LHCf The transverse and longitudinal momentum distributions for inclusive neutral pions in the very forward rapidity region have been measured with the Large Hadron Collider forward detector in proton–proton collisions at sqrt(s) = 2.76 and 7TeV and in proton–lead collisions at nucleon–nucleon center-of-mass energies of sqrt(s_NN) = 5.02TeV at the LHC. Such momentum distributions in proton–proton collisions are compatible with the hypotheses of limiting fragmentation and Feynman scaling. [...] CERN-PH-EP-2015-201.- Geneva : CERN, 2015 - 26.
