Properties of the hadron multiplicity distributions in 280 GeV/
c μ
+p interactions have been investigated. The c.m. energy dependence in the range from 4 to 20 GeV of the total charged multiplicities are presented. No variation faster than logarithmic is seen in the energy range of this experiment. Comparison with
νp and
ν
p
data at lower energy has been made and shows good agreement between μ
+p and
ν
p
total charged multiplicities. It has been found that the average forward multiplicity (charged hadrons with
x
F > 0) exceeds the average backward multiplicity (charged hadrons with
x
F < 0) in the whole energy range and presents a different energy variation. The average forward multiplicity has been compared to e
+e
− data and shows a similar dependence on energy. Little correlation was observed between the forward and backward multiplicities indicating that the current and target regions fragment almost independently.
