Abstract: (APS)

Within the framework of

k_{t}

factorization, we compute the differential cross section for the production of

B

and

D

mesons, using a general-mass variable-flavor-number scheme. Our calculations include all relevant

2 \to 2

processes. We explain how to include the

2 \to 1

process in our calculations but argue this is not (numerically) relevant at moderate transverse momentum due to its cancellation with the subtraction term. We apply this formalism to

p p

collisions and compare our results with ALICE and LHCb data at central and forward rapidity.

Note:
