Multiplicity distributions inν¯μpinteractions

Mean charged multiplicities in charged-current neutrino scattering on hydrogen and deuterium

“…The mean charged-hadron multiplicity in the muon neutrino and antineutrino charged-current reactions on hydrogen and deuterium has been measured in the Fermilab experiments E31 [14][15][16][17][18][19][20], E45 [21][22][23][24], and E545 [25][26][27] with the 15 ft bubble chamber and in the CERN experiments WA21 [28][29][30][31][32][33][34] and WA25 [35][36][37][38][39] with the Big European Bubble Chamber (BEBC). The data obtained with the Fermi National Accelerator Laboratory (FNAL) and BNL hydrogen bubble chambers before 1976 are gathered in Ref.…”

“…Table I summarizes the results of Refs. [14][15][16][20][21][22][23][26][27][28][29][30][32][33][34][35][36][37], represented in terms of the intercept and slope coefficients a and b of Eq. (1).…”

“…Also, we cannot utilize the data obtained after imposing the stringent kinematic cuts (e.g., Refs. [14,15,[18][19][20]25,38]) systematically distorting the value of n ch . A representative example is provided by the FNAL E31 experiment (ν μ p).…”

“…A representative example is provided by the FNAL E31 experiment (ν μ p). The data of the E31 experiment for the full phase space [16] are 065501-2 based on about 20% of the final data sample [20], but in the latter analysis, only such events were selected which satisfy the rather hard constraint 0.1 < y < 0.8. Hence we are forced to use the lower-statistics data from Ref.…”
