    "abstract": "Inclusive cross section for pion production in proton - proton collisions are\ncalculated based on unintegrated parton distribution functions (uPDFs). In\naddition to purely gluonic terms the present approach includes also quark\ndegrees of freedom. Phenomenological fragmentation functions from the\nliterature are used. The new mechanisms are responsible for $\\pi^+$ - $\\pi^-$\nasymmetry. In contrast to standard collinear approach, application of 2 $\\to$ 1\n$k_t$ - factorization approach can be extended towards much lower transverse\nmomenta, both at mid and forward rapidity region. The results of the\ncalculation are compared with SPS and RHIC data.",
