Transverse momentum parton distributions inspired by a quark potential model
Abstract
We derive a nonperturbative transverse momentum distribution for partons using a potential model to describe the quarkquark interaction inside the proton. We use this distribution to calculate the diferential crosssection of $\pi^0$production for intermediate values of transverse momentum in $pp$ collisions at high energies. Assuming a variable string tension constant for the quarkquark potential we obtain a very good description of the experimental data at different energies. The corresponding values of the mean transverse momentum of the partons are essentially lower than those obtained using a Gaussian transverse momentum parton distribution.
