B-hadron production in NNLO QCD
We calculate, for the first time, the NNLO QCD corrections to identified
heavy hadron production at hadron colliders. The calculation is based on a
flexible numeric framework which allows the calculation of any distribution of

Feb 13, 2020
The type II restriction endonuclease TseI recognizes the DNA target sequence 5'-G^CWGC-3' (where W = A or T) and cleaves after the first G to produce fragments with three-base 5'-overhangs. We have determined that it is a...
