Measurement of charged particle transverse momentum spectra in deep inelastic scattering

Transverse momentum spectra of charged particles produced in deep inelastic scattering are measured as a function of the kinematic variablesx and Q2 using the H1 detector at the epcollider HERA. The data are compared to different parton emission models, either with or without ordering of the emissions in transverse momentum. The data provide evidence for a relatively large amount of parton radiation between the current and the remnant systems.
