Particle production in proton-nucleus collisions beyond leading order

Claims

• The paper addresses: Particle production in proton-nucleus collisions beyond leading order.
• We describe the origin of, and the solution to, the negativity problem which occurs in the perturbative calculation of the cross-section for single-inclusive particle production in proton-nucleus collisions at next-to-leading-order.

Methods
