Description

As part of the investigation programme of the transverse spin and transverse momentum structure of the nucleon in semi-inclusive DIS processes, COMPASS has measured several transverse momentum distributions of the final state hadrons in DIS of 160 GeV/c muons off unpolarised targets.
Recently transverse momentum distributions were obtained by scattering the muons off an isoscalar target consisting of 6LiD beads immersed in a liquid 3He/4He mixture.
Here we present the first complete set of results for the transverse momentum distributions of hadrons produced in DIS off a liquid hydrogen target. These new results allow for a deeper investigation of the various kinematic dependences.
A novel leading-order analysis of the results, aiming to extract the mean value of the squared intrinsic transverse momentum of the quarks, is also presented.
