Understanding Bottom Production ∗


We describe calculations of bb production to next-to-next-to-leading order (NNLO) and next-to-next-to-leading logarithm (NNLL) near threshold in pp interactions. Our calculations are in good agreement with the bb total cross section measured by HERA-B. Factorization assumes it is possible to separate QCD cross sections into universal, non-perturbative… (More)
