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

Does the PI3K pathway promote or antagonize regulatory T cell development and function?
Regulatory T cells (Tregs) prevent autoimmunity and inflammation by suppressing the activation of other T cells and antigen presenting cells. The role of phosphoinositide 3-kinase (PI3K) signaling in Treg is controversial. Some...
