The studies on $$Z \rightarrow \Upsilon (1S)+g+g$$ Z→Υ(1S)+g+g at the next-to-leading-order QCD accuracy
Abstract In this paper, we carry out the next-to-leading-order (NLO) studies on $$Z \rightarrow \Upsilon (1S)+g+g$$ Z→Υ(1S)+g+g via the color-singlet (CS) $$b{\bar{b}}$$ bb¯ state. We find the newly calculated NLO QCD corrections to this process can significantly influence its leading-order (LO) res...
