Revisiting $B_c^{(*)}$ production in $Z$-boson decays at NLO in QCD
We study $B_c^{(*)}$ production in $Z$-boson decays at next-to-leading order (NLO) in QCD within the color-singlet nonrelativistic QCD framework. The analysis covers both the $1S$ and $2S$ pseudoscalar and vector states, extending the phenomenological study to radially excited $B_c$ mesons. We calculate direct producti...
