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).…”

“…The quoted errors for a and b are statistical only, except for the result of Ref. [33], where the statistical and systematic errors are added in quadrature. A misprint in the value of a, reported in Ref.…”

“…[16,22,27,34,39] and acceptable subsamples of data from Refs. [30,33,37]. There are several comments that we would like to make regarding the reasons for this choice.…”

“…[33] for both νp and νp reactions is based on the same data sample as in Ref. [34] and the main part of the results of Ref.…”
