C. Adloff et al., MEASUREMENT OF CHARGED-PARTICLE TRANSVERSE-MOMENTUM SPECTRA IN DEEP-INELASTIC SCATTERING, Nuclear physics. B, 485(1-2), 1997, pp. 3-22
Transverse momentum spectra of charged particles produced in deep inel
astic scattering are measured as a function of the kinematic variables
x and Q(2) using the H1 detector at the ep collider HERA. The data ar
e compared to different parton emission models, either with or without
ordering of the emissions in transverse momentum, The data provide ev
idence for a relatively large amount of parton radiation between the c
urrent and the remnant systems.
